The horizontal well located sand spraying and perforating device comprises a main body and a perforating direction locating mechanism, wherein the perforating directionlocating mechanism is installed at two ends of the main body. The perforating orientation can be determined by the perforating direction locating mechanism, according to the requirements of layered stress and formation stress, perforating and sand spraying can be selectively carried out, and located and oriented perforating and sand spraying operations can be precisely carried out to perforate casings and rocks to form holes. Casings and formations near wells can be perforated, the generated diameter and depth are larger and deeper than those generated by the conventional perforators, big spindle-shaped holes with a certain diameter are formed, and the horizontal well located sand spraying and perforating device increases the drainage area, reduces the reservoir contamination, improves theeffect of increase in yield, simultaneously has the functions of sand spraying, perforating and fracturing operations, and reduces the process of stringing and fracturing after perforating.
Description
Technical field
The utility model belongs to the downhole operation equipment of petroleum industry, and particularly horizontal well location abrasive perforating device is used for the horizontal well completion job execution of low permeability oil field.
Background technology
At present China nearly 50% verifies the hyposmosis reserves because production capacity is low, of poor benefits being difficult to of exploitation employ.How efficient, the economic hyposmosis reserves of employing are long-term difficult problems of exploring.The horizontal well in segments fracturing technique is the key technology that solves the low permeability oil field horizontal well development, and the hydraulic jet perforation pressure break is technological difficulties wherein.The research of hydraulic jet perforation pressure break project has further promoted the sizable application of horizontal well technology in oilfield prospecting developing.But the hydraulic jet perforation fracturing technique does not also have corresponding kit to satisfy this The Application of Technology at present, as kits such as horizontal well location abrasive perforating devices, thereby has restricted the advantage of horizontal well in LOW PERMEABILITY OILFIELD DEVELOPMENT.The conventional cumulative that uses launches the hole because the abrupt release high-energy can cause perforation tunnel rock texture heavy damage on every side at present, produces damaged area or compaction band, and nearly wellbore formation permeability is caused serious injury, and causes rock porosity and permeability decrease.Because existing conventional cumulative launches the function that the hole does not have same tubing string energy while abrasive perforating and fracturing work, also want the operation of other lower tubular column pressure break behind the perforation in addition, increase working procedure.
Summary of the invention
The purpose of this utility model provides horizontal well location abrasive perforating device, for the hydraulic jet perforation fracturing technique provides the underground work perforation tool.Solve present conventional cumulative and launch the damaged area of hole generation or the problem that compaction band can cause serious injury to nearly wellbore formation permeability.
The present technique solution can reach above-mentioned purpose: horizontal well location abrasive perforating device comprises body and perforation direction locating mechanism, and the perforation direction locating mechanism is installed in the two ends of body, utilizes the perforation direction locating mechanism to determine perforation orientation.
Compared with prior art, the utlity model has following useful effect:
1, the utility model is to utilize hydrodynamics momentum-impulse principle, and solid particle is quickened by water carrier, and high speed impact sleeve pipe and rock are penetrated and worn pipe and near wellbore formation, has avoided the oil reservoir compacting injury of conventional perforation, and there is not compaction band in the eyelet of formation.Nozzle of the present utility model is fixed in the spray-hole of body by nozzle carrier, has powerful jet power, and is bigger than the penetration depth of common perforating gun.Can form larger-diameter eyelet behind the perforation, eyelet rule on the sleeve pipe wall can be follow-up operation good flow channels is provided, thereby improves pressing crack construction efficient and success rate.
2, the utility model can carry out the perforation sandblast selectively according to the requirement of layering and reservoir stress, positions exactly, oriented perforating, sandblast operation.
3, this abrasive perforating device positioning and directing ground perforation sandblast, penetrate sleeve pipe and rock and form hole, can penetrate and wear pipe and near wellbore formation, diameter that produces and all more conventional cumulative bullet of degree of depth perforator bigger, darker, form the spindle macroscopic void of certain diameter, increase drainage area, reduced oil layer pollution, improved effect of increasing production.
4, the utility model has the function of abrasive perforating and fracturing work simultaneously, has reduced the operation of also wanting other lower tubular column pressure break behind the perforation.
