Abstract
The utility model provides an underground high-pressure water jet injection tool device. The head of a nozzle body is provided with front jet orifices communicated with the inner part of the nozzle body, the side wall of the tail part of the nozzle body is provided with back jet orifices communicated with the inner part of the nozzle body, the inner front end of the nozzle body is provided with a supercharger, a connection buckle is arranged behind the supercharger, and a water distribution wheel is arranged in the connection buckle. In the utility model, the number of the front jet orifices processed at the head of the nozzle body is smaller than the number of the back jet orifices processed at the tail part, and high-speed high-pressure water flow are simultaneously jetted from the front jet orifices and the back jet orifices. Since the head displacement is smaller than the tail displacement, a frontward thrust force is formed, the nozzle body passes through an oil pipe, carries a high pressure hose to conduct stratum perforation, and injects high pressure water flow to the stratum, and the injection distance can reach 100m to 190m; and since the nozzle body carries the high pressure hose to enter the stratum, distant crude oil further than 100m beyond an oil well shaft can be communicated, thereby the single well output of crude oil is increased, and the effects of oil well production increase, gas well production increase and water well injection increase are achieved.
Description
Technical field
The utility model belongs to producing oil, gas, water from well; Solubility maybe can be dissolved the method or the equipment technical field of material or slurry of mineral, is specifically related to the part of perforator.
Background technology
The traditional way of petroleum industry recover petroleum and natural gas is to carry out drilling well earlier, setting of casing well cementation then, and by the perforating gun perforation, the perforating bullet detonation punctures sleeve pipe in the down-hole, and the formation pit shaft is communicated with the stratum, comes recover petroleum and natural gas.Gun perforation process, the cost height, efficient is low, and the range that perforation is bound to has only 1m, and formed aperture is little, and high enegry gas fracturing also can only penetrate 3～5 meters stratum, has influence on the output of petroleum and natural gas.And in the transportation of perforating bullet, very dangerous, need public security department to provide a certificate, the special train transportation has strengthened cost of production.
The someone has invented the high-pressure hydraulic perforator in recent years, adopts this perforator perforation on the rock of down-hole, and the critical piece of high-pressure hydraulic perforator is a fluid jet nozzle.The patent No. is 97239624.1, denomination of invention is " a high-pressure hydraulic perforator eddy flow nozzle ", end at housing is provided with union or connects the hole, in housing, establish Surface Machining the eddy flow groove that can make fluid change flow direction or eddy flow of whirl hole are arranged, the right side constitutes cone-shaped eddy flow chamber in the housing, top in cone-shaped eddy flow chamber is processed with spray-hole, the outside of housing is processed with chip area, is provided with the spacing pawl at the other end of housing.This hydraulic perforating device eddy flow nozzle, complex structure has strengthened cost of production, and at the following perforation of 2000m, fault rate is too high, can't carry out operation.
In high-pressure hydraulic perforator technical field, current need urgently solve to such an extent that technical problem provides a kind of simple in structure, shower nozzle that perforation efficiency is high.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the shortcoming of above-mentioned high-pressure hydraulic perforator nozzle, and a kind of simple in structure, easy and simple to handle, down-hole high pressure water jet spraycan device that the stratum perforating effect is good is provided.
Solving the problems of the technologies described above the technical scheme that is adopted is: be processed with on the preceding spray orifice a that links with sprayer body inside, the afterbody sidewall at the head of sprayer body and be processed with the back spray orifice c that links with sprayer body inside, the sprayer body Inner Front End is provided with booster, be provided with behind the booster to connect and detain, be provided with the branch water wheels in the connection button.
Spray orifice a has 3～6 circumference in equal parts arrangements in vertical section before of the present utility model, and the aperture of preceding spray orifice a is that angle α is 15 °～40 ° between 0.1～0.5mm, center line and sprayer body 1 axis.
Back spray orifice c of the present utility model has 10～15 circumference in equal parts arrangements in vertical section, and the aperture of back spray orifice c is that angle β is 10 °～30 ° between 0.1～0.5mm, center line and sprayer body 1 axis.
The utility model is processed with preceding spray orifice at the sprayer body head, afterbody is processed with the back spray orifice of quantity more than preceding spray orifice, high speed and high pressure current spray orifice in the past spray simultaneously with the back spray orifice, because the head discharge capacity is less than the discharge capacity of afterbody, form thrust forward, sprayer body passes oil pipe, carry high-pressure hose and carry out the stratum perforation, to stratum inject high pressure current, jet length can reach 100～190m, and sprayer body is carrying high-pressure hose and entering the stratum, can link up well wellbore 100m distant place crude oil in addition, improve the well yield of crude oil, reach oil, oil/gas well stimulation, the effect of intensified injection of wells.
