Definitions

  • the invention concerns a threaded element for a tubular threaded joint.
  • the threaded elements provided at the end of a tubular component (tube or coupling) and used in hydrocarbon wells firstly have to be protected from corrosion during transport and storage on the drilling site and for that they are traditionally coated with protective oils or greases on leaving the manufacturing workshop.
  • the makeup operations are carried out vertically under a high axial load, for example under the weight of a tube of several metres in length (typically 10 to 13 metres in length) which is to be assembled by the threaded joint vertically, and that gives rise to risks of galling, in particular of the threadings.
  • That load can also be localised by slight misalignment of the axis of the threaded elements to be assembled because the tube to be assembled is suspended vertically, which increases the risk of galling.
  • FIG. 1 shows the procedure for assembly by means of a threaded joint of two tubes 1 and 2 which are 10 to 13 metres in length on the building site with a misalignment, power tongs 3 being used to make up the male threaded portion 4 of the tube 1 into the female threaded portion 5 of the tube 2 .
  • U.S. Pat. No. 6,933,264 proposes replacing the double coating operation by a single coating operation which is implemented at the workshop where the threaded elements are produced, using a thin layer of a lubricant of waxy consistency (referred to as semi-dry), comprising at least one extreme-pressure additive with a chemical action.
  • semi-dry a thin layer of a lubricant of waxy consistency
  • Such a semi-dry coating suffers from the disadvantage of requiring mechanical protection from pollution by particles of dust or sand during transport and storage.
  • U.S. Pat. No. 6,679,526 B2 and WO 2004/033951 provide for the application of a separate layer of a corrosion-inhibiting material (a metal salt of carboxylic acid for the first document, and epoxy resin containing zinc particles for the second document).
  • a corrosion-inhibiting material a metal salt of carboxylic acid for the first document, and epoxy resin containing zinc particles for the second document.
  • the aim of the invention is to remedy the disadvantages of the known dry or semi-dry coatings and greases and thus to improve the situation as regards tribology and productivity of the application of the coating.
  • the invention aims to improve the situation as regards corrosion of the threaded elements.
  • Makeup under working conditions means makeup operation which is generally carried out in a vertical position, in which (i) a first threaded element is held vertically and fixed, and (ii) a second threaded element which is to be made up onto the first threaded element, disposed at or fixed to the lower end of a tube which may be 13 metres long, is held substantially vertically above the first threaded element by a lifting apparatus, the second threaded element then being made up into the first using a suitable device such as motor-driven power tongs.
  • breakout under building site conditions means breakout of the first and second threaded elements which are disposed vertically and thus supporting the weight of a tube and subject to possible misalignment, the tube which is to be broken out being suspended from a lifting apparatus.
  • the invention concerns in particular a threaded element for a tubular threaded joint which is resistant to galling, comprising a threading covered with a thin coating in the solid state, not sticky to the touch and adhering to the substrate, which comprises a solid matrix and, in said matrix, a dispersion of particles of at least one solid lubricant.
  • the solid matrix is lubricating and presents a rheological behaviour of the plastic or viscoplastic type.
  • the dispersion of particles of at least one solid lubricant comprises particles of lubricant of a single one of classes 1, 2, 3 or 4.
  • the solid matrix comprises at least one thermoplastic polymer and debris re-agglomeration means capable of re-agglomerating the debris formed in the vicinity of the surface of said threaded element by friction.
  • the invention also concerns a tubular threaded joint comprising a male threaded element and a female threaded element characterised in that one at least of said threaded elements is as defined hereinbefore, and a process for finishing a tubular threaded element, wherein there is applied at least to the surface of the threading a solid anti-galling coating in the form of a thin layer as defined hereinbefore after having subjected the surface to be coated to a surface treatment for improving the adhesion of the coating.
  • the process according to the invention may comprise at least some of the following particularities:
  • FIG. 1 diagrammatically shows two tubes ready to be assembled by makeup of their threaded elements in a hydrocarbons well
  • FIG. 2 shows on an enlarged scale a portion of the threading surface of a threaded element, the porosity of which is impregnated with nanomaterials according to the process of the invention
  • FIGS. 3 and 4 diagrammatically show devices which can be used for carrying out the process according to the invention.
  • FIG. 5 diagrammatically shows a device for evaluating the coating of the invention by a makeup and breakout test.
  • the invention concerns a threaded element for a tubular threaded joint which is resistant to galling.
  • the threaded element is provided with a threading covered with a thin coating in the solid state, not sticky to the touch and adhering to the substrate, which withstands numerous makeup and breakout operations.
  • the coating of the threaded element comprises a solid matrix and at least one solid lubricant composed of particles which are dispersed in the solid matrix.
  • the invention is based on a study of the tribological behaviour of certain materials and refers to certain notions which are set forth hereinafter.
  • Solid lubricants in a dry-state hydrodynamic lubrication condition when dispersed in a fluid or viscoplastic material, have a tendency to become fixed on the surfaces in a stable fashion, modifying the frictional characteristics thereof. They are transferred and bonded to the surface by chemical bonding, which gives rise to a high level of resistance to wear and an improvement in the frictional properties. Depending on the nature of the solids, this imparts to the surfaces an anti-wear protection, resistance and anti-wear properties at the extreme pressures generated by high surface-load stresses referred to as Hertzian stresses, and a low coefficient of friction over a wide range of loads and frictional speeds. Said properties for generating a transfer film effect or a leafing effect are used for the types of friction where the surfaces are repeatedly subjected to stressing, such as that produced during makeup and breakout of systems of tubular threaded joints.
  • the third frictional body is the substance which is interposed between two surfaces which are in contact during friction.
  • the surfaces in contact under a load stress are elastically deformed, defining a contact zone of a certain area.
  • the load applied divided by that area defines the Hertzian pressure or stress.
  • solid non-plastic materials can undergo internal shearing effects, reducing their service life due to fatigue of the material, while solid plastic materials undergo that shearing effect without structural degradation.
  • This term is used to mean a system which makes it possible to fix or carry an active principle to a given location. It also serves as a cohesion agent for a heterogenous system and can have functions which complete those of the active principles that it bonds or carries.
  • the solid matrix of the invention is in particular lubricating and has a rheological behaviour of the plastic or viscoplastic type.
  • Bodies having base properties can be combined into a complex body with totally different characteristics and behaviour. In the case where such behaviours lead to performances which are superior to the combination of those of the constituents, that is referred to as synergy.
  • the third body generated or present in a frictional situation owes its lubricating or non-lubricating properties to its physical state in accordance with Table 1 hereinafter.
  • the materials used in the matrix according to the invention belong to category 1 in Table 1.
  • the solid matrix of the invention comprises at least one thermoplastic polymer.
  • thermoplastic qualifies a fusible polymer capable of being reversibly softened and then melted by heating respectively to the temperatures T g and T m (glass transition point and melting temperature) and solidified by cooling.
  • Thermoplastic polymers are transformed without chemical reaction.
  • Thermoplastic polymers are used in the invention in order to achieve a viscous flow, under frictional stress, while statically preserving a structure which is solid and dry (non-sticky to the touch) and stable.
  • thermosetting polymers have no or little viscous behaviour under stress.
  • This term embraces soaps of alkali and alkaline-earth metals and other metals. These are fusible compounds having capacities of flow between surfaces (category 1 in Table 1).
  • This term covers fusible substances having lubricating properties, of various origins (mineral, in particular resulting from the distillation of petroleum, vegetable, animal or synthetic), with a more or less pasty or hard consistency and with a melting temperature and dropping point which can vary widely depending on their nature.
  • a solid lubricant is a solid stable body which, being interposed between two surfaces in friction, makes it possible to lower the coefficient of friction and to reduce wear and damage to the surfaces.
  • Class 1 solid bodies owing their lubricating properties to their crystalline structure, for example graphite, boron nitride BN, zinc oxide ZnO.
  • Class 2 solid bodies owing their lubricating properties on the one hand to their crystalline structure and on the other hand to a reactive chemical element of their composition, for example molybdenum disulphide MoS 2 , graphite fluoride, tin sulphides and bismuth sulphides.
  • Class 3 solid bodies owing their lubricating properties to their chemical reactivity, for example certain chemical compounds of thiosulphates type (for example Desilube 88 marketed by Desilube Technology Inc.).
  • Class 4 solid bodies owing their lubricating properties to a plastic or viscoplastic behaviour under frictional stress, for example polytetrafluoroethylene PTFE and polyamides.
  • the invention uses particles of solid lubricants belonging to one of the foregoing classes.
  • the inventors preferably used as solid lubricants compounds of class 2 and in particular compounds which have been little used hitherto such as graphite fluorides and complex tin or bismuth sulphides. According to the inventors those compounds differ from the traditional solid lubricating products such as graphite, molybdenum disulphide or tungsten disulphide because of their greater capacity for bonding to metals and their levels of performance at extreme pressures which are markedly greater.
  • the inventors in particular sought solutions which do not involve graphite which is capable of facilitating the occurrence of corrosion or molybdenum disulphide, that compound being known to be unstable in particular in the presence of moisture and to give off sulphur oxide which is corrosive for steel or hydrogen sulphide which possibly makes steel sensitive to deferred hydrogen-induced stress rupture (sulphide stress cracking or SSC).
  • graphite which is capable of facilitating the occurrence of corrosion or molybdenum disulphide, that compound being known to be unstable in particular in the presence of moisture and to give off sulphur oxide which is corrosive for steel or hydrogen sulphide which possibly makes steel sensitive to deferred hydrogen-induced stress rupture (sulphide stress cracking or SSC).
  • Spherical fullerenes are of a size of some tens of nm in the case of the mono-layer form and greater than about 80 nm in the multi-layer form. They act on surfaces by stably blocking the sites created by the surface roughnesses and blocking deteriorations of flaking type.
  • the invention takes account of the different stresses to which the tubular threaded joints are subjected in operation thereof.
  • the frictional system during makeup and breakout of the threaded joints is made complex by the great variety in frictional speeds which is encountered. In fact the speeds can be relatively high during makeup and nearly zero at the end of makeup or the beginning of breakout.
  • the inventors developed a matrix whose properties involve a plastic characteristic leading to a viscous flow under stress and complying with all the speed situations which are encountered.
  • the use of a plurality of constituents is necessary for the highest-performance systems in order to adapt them to that great variety of shearing effects. That matrix makes it possible to hold the other active elements in place and contribute to the production of stable transfer films or leaves.
  • Thermoplastic resins generally having plastic characteristics have been selected and the inventors gave the preference to polyethylene among all of the existing viscoplastic polymers, in preference to other viscoplastic polymers such as polyamide-6, polyamide-11 and polypropylene which give rise to problems of application because of their high viscosity in the molten state.
  • the choice was for those having melting points of higher than 105° C.
  • the invention further provides debris re-agglomeration means capable of re-agglomerating the debris resulting from frictional phenomena at the level of the contact surface of the threaded elements. Those re-agglomeration means make it possible to re-agglomerate the debris as soon as it is formed.
  • the inventors in particular found by experiment that improvement in the properties in terms of re-agglomeration of debris and plasticity of the matrix is achieved by the addition of re-agglomeration means of metallic soap type, among which soaps of calcium, bismuth and zinc gave excellent results in terms of the number of makeup and breakout operations under the above-described site conditions.
  • re-agglomeration means of metallic soap type among which soaps of calcium, bismuth and zinc gave excellent results in terms of the number of makeup and breakout operations under the above-described site conditions.
  • soaps zinc stearate was selected for its intervention in synergistic relationship with the corrosion inhibitors studied hereinbefore.
  • the inventors prepared a suitable system of additives, comprising a solid lubricant formed by particles dispersed in a solid matrix.
  • the inventors preferred to employ solid lubricants capable of guaranteeing a lubricated operating state even in a quasi-static condition.
  • the inventors in particular used one or more solid lubricants in class 2.
  • corrosion inhibitors into the matrix.
  • derivatives of calcium sulphonates and more particularly those arising out of the association of calcium oxide and calcium sulphonates in a medium formed by waxes, petroleum resins or paraffins such as the product marketed by LUBRIZOL under the name ALOX 606 have shown themselves particularly performing, but other compounds can equally be used such as those of amino, aminoborate, quaternary amine, sulphonate super-alkalinised on polyalfaolefin, strontium phosphosilicate, zinc phosphosilicate and borate carboxylate type.
  • Resistance to corrosion can be further improved by associating the selected corrosion inhibitor with compounds acting in accordance with other mechanisms for blocking corrosion.
  • zinc stearate in particular presents synergistic properties with corrosion inhibitors while greatly contributing to the lubricating behaviour of the matrix.
  • the main test of anti-corrosion protection is the saline mist test carried out in accordance with the standard ISO 9227 and evaluated by the index Re in accordance with ISO EN 2846-3 on a plate treated by phosphatation with manganese (deposit of 8 to 20 g/m 2 of phosphate).
  • the composition of the matrix is provided for blocking the debris resulting from friction on the surface in order to eliminate the possibilities of environmental pollution. Thanks to the appropriate composition of the matrix such debris is re-agglomerated as soon as it is formed.
  • compositions under study an inadequacy of performance in terms of re-agglomeration led to a search for other types of product with a re-agglomerating function.
  • highly viscous polymers such as alkyl polymethacrylates (PAMA), polybutenes, polyisobutenes and polysiloxanes, with excellent results in the debris re-agglomeration test being obtained with a PAMA of a kinematic viscosity of 850 mm 2 /s at 100° C. marketed by ROHMAX under the name VISCOPLEX 6-950.
  • the inventors more especially envisaged the addition of 2% or less of surface-active silicone, preferably polydimethylsiloxane, or DC56 (marketed by DOW CORNING).
  • surface-active silicone preferably polydimethylsiloxane, or DC56 (marketed by DOW CORNING).
  • the invention thus associates two groups of products, with systematic utilisation of the synergistic interactions between them:
  • the process according to the invention comprises a surface preparation of the elements to be lubricated.
  • the object of that impregnation operation is to be block and saturate the sites created by the porosity by a material having a passivating action for protecting the surface from corrosion while preserving good adhesion for the coating.
  • FIG. 2 diagrammatically shows the impregnation of particles 11 into the porosity sites 12 of a metallic substrate 13 .
  • the inventors noted improvements in the level of performance in the saline mist test in accordance with the above-mentioned standards (increase by 20% in the time for corrosion to appear), by inserting particles of zinc oxide of nanometric size (200 nm on average), applied in a simple dispersion in water.
  • one or more anti-oxidants may be added.
  • Polyphenolic compounds, derivatives of naphthylamine and organic phosphites constitute the principal families of anti-oxidants.
  • the inventors more particularly chose a combination of the products IRGANOX® L150 (system of polyphenolic and amino anti-oxidants) and IRGAFOS® 168 (tris(2,4-di-tert-butylphenyl) phosphite) from Ciba-Geigy.
  • the invention also concerns modes of applying the coating, facilitating its industrialization. Different techniques are used for that purpose, those which appear most appropriate being described hereinafter.
  • the technique of spraying in the molten state involves keeping the product at high temperature in the liquid phase and spraying it by means of a thermostatically controlled spray gun.
  • the product is heated at between 10 and 50° C. above its melting temperature and sprayed onto a temperature pre-heated to a temperature higher than the melting temperature in order to achieve good surface covering.
  • the spraying operation is carried out on a threaded element which is not pre-heated (that is to say which is maintained at ambient temperature).
  • the composition of the coating is then adapted by the addition of a small amount of surface-active agent, for example 2% at maximum and preferably 0.6% to 1.0% of surface-active silicone, preferably polydimethylsiloxane or DC56 (marketed by DOW CORNING).
  • FIG. 3 shows an example of an installation for carrying out the process.
  • the product 20 is melted in a vessel 21 stirring using a propeller stirrer 22 and then passed by a controllable-flow pump 24 through a pipe 25 to a spraying head 23 which is also supplied with air by a compressor 26 .
  • the components 21 and 23 to 26 are regulated as regards temperature.
  • Another technique is that of emulsion application in which the product is sprayed in the form of an aqueous emulsion.
  • the emulsion and the substrate can be at ambient temperature, a drying time then being necessary. That drying time can be considerably reduced by pre-heating the product at between 60 and 80° C. and/or the surface at between 50 and 150° C.
  • FIG. 4 illustrates the technique involved in thermal spraying or spraying through a flame.
  • the product 30 in powder form is projected onto the surface to be coated by means of a gun 31 supplied with air 32 and combustible gas 33 .
  • the powder melts on passing through the flame 34 and homogenously covers the target.
  • the examples involve a threaded joint of type VAM TOP HC of a nominal diameter of 177.8 mm (7 in) and of a linear mass of 43.15 kg/m (29 lb/ft) of low alloy steel (grade L80) in accordance with the technical specification edited by the OCTG division of Vallourec & Mannesmann Tubes.
  • the male threaded element Prior to application of the coating the male threaded element was subjected to phosphatation with zinc (weight of the layer was between 4 and 20 g/m 2 ) and the female threaded element was subjected to phosphatation with manganese (the weight of the layer was between 8 and 20 g/m 2 ).
  • the threaded elements are preheated at 130° C. and thermal spraying is used to apply thereto a layer of a thickness of 35 ⁇ m of a product kept in the molten state at 150° C., of the composition by weight of one of Examples Ito VI hereinafter in which
