Description
Technical field: the present invention relates to a kind of oil gas well downhole tool, particularly a kind of abrasive water-jet many radiating aperture of down-hole extra-deep hole drilling device.
Background technology: most oil gas wells will be linked up at the oil gas that the oil gas interval carries out between perforating job realization stratum and the pit shaft after finishing the production string well cementation.Common perforating methods has: bullet perforating, cumulative launch the hole, compound cumulative launches hole, hydraulic jet perforation, hydraulic sand blasting slot perforation, abradant jet down-hole deep penetrating perforating, waterpower deep penetrating perforating etc.The most frequently used method has at present: cumulative launches the hole, compound cumulative launches the hole, and perforating depth is generally between 0.4～0.7 meter.
Because most oil gas wells rotate under mud circulation and are drilled to, and in the wellbore stratum, have the nearly well of 0.5-1.5 rice barite contaminated zone, along with the carrying out of recovering the oil and producing, this contaminated zone can enlarge, even reaches several rice, has a strong impact on the oil gas well production.All types of hole technology of launching, a common shortcoming is all arranged: perforating depth is lower, can not effectively pass through nearly well contaminated zone; The compacting perforation tunnel causes secondary pollution etc.
Though hydraulic jet perforation, hydraulic sand blasting slot perforation can increase the oil reservoir bare area and reach the volume increase purpose, general perforating depth has only 0.7～1.0 meter, can not penetrate nearly well contaminated zone fully.And, to launch the hole with the most frequently used compound cumulative and compare, the advantage that perforating depth is big is outstanding, and use cost is higher, uses less.
Chinese patent literature 02270099.4 has been introduced a kind of abradant jet down-hole deep penetrating perforating device, is in a kind of conceptual phase substantially, does not see the report of related application at present.Only from document, there is following shortcoming in this device: the single operating efficiency of playpipe is low, and discharge capacity is little, landwaste is difficult for the row of returning, and playpipe exists unstability and sand card etc.
Waterpower deep penetrating perforating technology is to be invented by American He Man J Shu Ershite, he with this art applications Chinese patent, the patent No. is 86108916, the basic principle of this technology is to drive drift with bigger hydraulic coupling earlier to wash a hole open on sleeve pipe, drive a small hose with fluid power then, pass the aperture on the drift, the small hose front end is equipped with a jetting nozzle, behind the highly pressurised liquid process jetting nozzle, penetrate cuts formation at a high speed.Jet pipe stretches out the degree of depth generally at 1～2 meter.This technology shows that in a small amount of The field that China has carried out practicality is poor.Complex structure, downhole control valve spare are more, higher to water quality requirement except having, puncher frangibility, sebific duct be easily around shortcoming such as bent, that reliability is low, topmost shortcoming is that the be hampered high-pressure rubber pipe of easy bending can't carry out real eyelet deep penetration, the inefficiencies of the broken rock of pure water and powerless for firm hard formation.
Summary of the invention: the objective of the invention is actual needs at oil-gas field development, overcome above-mentioned various perforating technology, particularly the various shortcomings of waterpower deep penetrating perforating technology through studying for a long period of time and testing, provide a kind of many radiating aperture of abrasive water-jet extra-deep hole drilling device of novel practical.Promptly provide a kind of and utilize the high-pressure grinding material water jet technology to bore simultaneously three or more in the down-hole, the degree of depth reaches the drilling equipment in the super dark radial radially duct more than the 2-5 rice.
The objective of the invention is to spray cutting sleeve pipe and the outer cement of pipe and stratum and bore simultaneously that the downhole hardware of a plurality of radial radial passages realizes by developing a kind of high pressure abrasive water.Concrete scheme is as follows:
The present invention mainly is made up of multitube steering gear, work string, driving and spraying system, control system.The multitube steering gear have main body, roller and or slide plate; Work string is composed in series by fluid cylinder, outer tube short circuit, outer tubing string from bottom to up successively; Drive the jet pipe bundle and the flow jet flow drill that have liquid inlet joint, piston, piston packing, single jet pipe composition with spraying system; Roofbolt and guider in control system comprises.
The multitube steering gear is core of the present invention, and it has three or more vertical straight trough on the main body circumferencial direction, be equipped with in each straight trough roller and or slide plate, their constitute a slideway that can pass through for single jet pipe and flow jet flow drill; And aim at each slideway inlet in main body upper inner circumference direction and have three or more guide groove.Driving from top to bottom is connected in series successively with liquid inlet joint, piston, jet pipe bundle and the flow jet flow drill of spraying system, and piston and dress piston packing thereon can move up and down in the fluid cylinder of work string; The jet pipe bundle is made up of the single jet pipes binding of three or many, and a flow jet flow drill respectively is equipped with in each single jet pipe lower end; The intrafascicular single jet pipe number of jet pipe equates with the vertical straight trough number of multitube diverter body; Single jet pipe is metal tube or wire braided hose.The guider of control system enters the orientation that long keyway on the fairlead is realized the jet pipe bundle, i.e. guiding automatically by being fixed on feather key on the guide sub; Interior roofbolt is to connect to drive and rod string or wire rope or the coiled rod of spraying system to ground, can control to drive and the spraying system motion.
The upper end of multitube steering gear and the fluid cylinder of work string join; Drive with the upper end and the control system of spraying system and join, they are positioned at work string and multitube steering gear inside and can seesaw within it, in the time of forward, under the pressure effect of high pressure abrasive water, the flow jet flow drill of jet pipe bundle and its lower end is separately entered downwards gradually by the guide groove in the multitube steering gear from bottom to up and passes through each slideway on the multitube diverter body, make each single jet pipe and flow jet flow drill from vertical direction steering horizontal or radial direction, with radial the stretching out of a plurality of single jet pipes, at this moment, high pressure abrasive water penetrates the cutting sleeve pipe at a high speed through each flow jet flow drill, manage outer cement sheath and stratum, can form three or more super deeply radially duct bigger simultaneously than the diameter of jet pipe own; In the time of backward, can be on ground will drive and reset with spraying system or upwards trip out by control system.
Modern design of the present invention, rational in infrastructure, cost is low, and the efficient height can be realized the multichannel degree of depth perforation of subterranean oil gas-bearing formation and significantly improving of oil and gas production.
