Definitions

  • FIG. 2 is a cross-sectional view of an embodiment of a plug with a check valve and an adapter mandrel with a secondary ball.
  • Fig. 3E is an external side view of a plug with a split ring assembly with multiple partially split (pre-set) rings, pre-test in pre-set position.
  • Fig. 3E1 is a partial external side view of the plug of Fig. 3E in a set position, also showing the casing.
  • Fig. 3F is an exploded cross-sectional partial illustration of the plug of Fig. 3E, pre-set.
  • the disclosed plug dissolves in conjunction with natural wellbore fluid, or operator added fluid, namely an aluminum dissolving or melting medium.
  • natural wellbore fluids produced from the formation flow through the plug's aluminum mandrel and about its other aluminum parts and, over a predetermined duration of time, dependent on plug composition, fluid composition, temperature, pH and the like, substantially dissolve the plug's mandrel and other aluminum parts. As the mandrel and other parts dissolve, fluid reaches the remainder of the plug and begins to dissolve the remainder of the plug. The plug dissolves substantially completely.
  • inserts 1 19 are provided on the slips 118 as known in the art.
  • Slips 1 18 may be made of aluminum, cast iron, ceramic, composite, tungsten carbide, or any combination thereof.
  • slips 1 18 are comprised dissolvable of aluminum as set forth in more detail below.
  • Inserts 1 19 may be cast iron or other hard suitable material.
  • an acid fluid such as an HC1 solution may be introduced into the well to help the solution of the aluminum elements of the cement retainer.
  • the cement retainer can be set with wire line or coiled tubing and conventional setting tools.
  • the slips may be cast iron in one embodiment (to be milled out) or as set forth in Figs. 4E1 through 4E4, or conventional.
  • An anti-seize compound may be used during tool assembly between the inner surface of the mandrel and the outer surface of the ring to provide more accurate shear points, the pressure differentials at which the pins shear and the pump out ring is released, and to reduce "stiction".
  • One such material is Loctite® Anti-Seize.
  • Such a material may also be used between adjacent rings of the multi-ring split ring assemblies and at surfaces where cones meet the rings of the split ring assemblies to reduce the likelihood of friction interfering with the tool's intended functions when subjected to downhole setting pressures.
  • ball 30/130 is "free” and may be dropped into the casing after the tool is set (and after the pump out ring is pumped out, if one is used). In another embodiment, as seen in Figs. 2, 3, 4A, 9A and 9B, ball 30/130 is run in with the tool.
  • split ring describes the post set configuration of all three of these embodiments as well as the pre-set configuration of embodiments (1) and (2). All may be used in place of a conventional elastomeric seal element or pack off element.
  • split ring assembly typically includes multiple ring elements, but may have a single ring (see Fig. 3D for example).
  • continuous (that is, not split in an unset condition) rings 151/152 have breakable separation grooves 154 as shown in Figs. 7A-7C on upper and/or lower surfaces, or lines of multiple weakening holes (not shown).
  • a ring may have one or more separation grooves 154. There may be more than two rings, such as four (two on each wedge) or six, etc.
  • Separation grooves 154 are shaped and sized so ring or rings 151/152 are continuous and securely held about mandrel (now shown in Figs. 7A-7C) until setting begins, but will preferentially separate along grooves 154 when wedges 122 force rings 151/152 radially outward during setting of the tool.
  • the expandable metal rings are under pressure squeezing them outward and the further degradation and softening of the outer surface of the rings permits them to be forced more closely against the inner casing wall, further sealing the outer surface of the rings to the inner casing wall.
  • the material of the rings such as frusto-conical rings 222 a 1 - d 1 is different from one ring to the adjacent ring.
  • the rings may be made of alternate anodic/cathodic materials. (See Fig. 3F1) Formation or downhole fluids are often electrolytic in nature. Constructing the rings of alternating material with different anodic/cathodic potentials generates electrochemical corrosion.
  • Aluminum may be more active than the iron of the casing and act as a sacrificial anode.
  • the aluminum of the rings may be an alloy more active than other parts of the tool, including other aluminum parts which they contact or are in electrolytic communication.
  • a method of using the disclosed aluminum plug 10/1 10 is to determine the aluminum plug's dissolvablability characteristics, volume of formation fluid flow, fluid temperature and acidity of the formation fluid to determine when the particular aluminum plug being used in the particular well will be sufficiently dissolved after insertion into the well for the subsequent targeted purpose.
  • the subsequent targeted purpose may be further completion work without needing to drill out or remove the plug, production of the well without needing to drill out or remove the plug, or permanently leaving the plug in the well.

Abstract

Selon l'invention, un bouchon de fond de trou à utiliser dans des complétions de puits de pétrole et de gaz constitué d'aluminium se dissout dans les fluides de puits de forage naturels, comporte un joint soluble constitué de bagues fendues en aluminium ou d'un élastomère dégradable, comporte une bague de pompage de secours, et peut être fourni sur le site du puits sous la forme d'un kit à pièces interchangeables pour une adaptation aux besoins du puits, ce qui fournit un bouchon sans intervention dans un puits.
