Abstract
The utility model relates to a high pressure nozzle for hydraulic perforation, which mainly solves the problem that the existing nozzle is short in service life and low in work efficiency. The high pressure nozzle for hydraulic perforation comprises a nozzle body, wherein a cone-shaped transitional hole of the nozzle body is internally sleeved with a wear-resisting lining matched with the cone-shaped transitional hole. The wear-resisting lining is provided with the cone-shaped transitional hole. The periphery of a liquid inlet hole end of the wear-resisting lining leans against the end surface of the nozzle body and is fixed by a pressing cap. The nozzle changes the structural shape of the liquid inlet end of the existing nozzle and fixing manner of the wear-resisting lining so as to prolong the service life and improve the work efficiency.
Description
Technical field
The utility model relates in the oil recovery field, oil field, producing well is carried out a kind of hydraulic perforating used on the deep penetrating high-pressure spray gun of hydraulic perforating use high pressure nozzle.
Background technology
Along with continually developing of oil field, be to excavate the reserves of thin poor reservoir, to conventional perforating technology can't perforation the well section, use high-pressure hydraulic slot through-transmission technique, sleeve pipe is carried out hydraulic jet perforation, set up gas channel.The position of perforation is the degree of depth of several kms in the down-hole usually, and the hydraulic perforating instrument of going into the well must accurately put in place, requires the certain degree of depth of perforation regular shape earth penetrating.Yet the nozzle on the high-pressure hydraulic spray gun that uses at present uses after a period of time owing to reasons in structure; Nozzle can change shape and size under the effect that contains the sand jet, at the import meeting generation eddy current of nozzle, and damage inlet end face and nozzle inner walls; The pressure that nozzle is penetrated does not reach requirement; And the wear-resisting pipe of nozzle body liner can produce under the effect of high-pressure hydraulic and move axially or come off, and causes the application life of nozzle short, inefficiency.
The utility model content:
In order to solve the problem that easy infringement of the entrance point that has nozzle now and bushing pipe come off, the utility model provides a kind of hydraulic perforating to use high pressure nozzle.This nozzle has changed the planform of existing nozzle liquid feeding end and the fixed form of internal lining pipe, has avoided the generation of the problems referred to above, increases the service life and has improved operating efficiency.
The technical scheme of the utility model is: hydraulic perforating is used high pressure nozzle; Comprise nozzle body; Wherein, the tapering transition hole of said nozzle body is built-in with the anti-wearing liner of suit with it, and said anti-wearing liner has the tapering transition hole; And the peripheral flange brim of wear-resisting bushing pipe inlet opening end leans against on the end face of nozzle body, and by fixing through bolt and pressure cap.
The beneficial effect of the utility model is: owing to adopt technique scheme; Inlet end to the liquid outlet end of anti-wearing liner is to little circular cone transitional pore from big on the nozzle body; When water under high pressure passes through the anti-wearing liner of nozzle; Can not produce eddy current, avoid of the damage of high pressure eddy current the entrance point inwall; And because the anti-wearing liner of nozzle body and liner is the cone suit; And the end is equipped with pressure cap and is compressed through bolt; Prevent moving axially and obscission of anti-wearing liner, after anti-wearing liner damages, can dismantle pressure cap and change anti-wearing liner; Thereby prolong the application life of nozzle effectively, and increase work efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model.
1-nozzle body among the figure, 2-anti-wearing liner, 3-pressure cap, 4-lock bolt, 5-tapering transition hole.
The specific embodiment
Be described further this use is novel below in conjunction with accompanying drawing:
By shown in Figure 1, this hydraulic perforating is used high pressure nozzle, comprises nozzle body 1, anti-wearing liner 2; Pressure cap 3 and lock bolt 4, wherein, the tapering transition hole that the endoporus of said nozzle body 1 is; Outer cylinder is the screw thread that is connected with tubing string, the anti-wearing liner 2 that suit cooperates with it in the tapering transition hole, and said anti-wearing liner 2 also has tapering transition hole 5; The big end in tapering transition hole 5 is a liquid feeding end, and small end is an outlet end, when water under high pressure sand liquid passes through anti-wearing liner 2; Can not produce eddy current, avoid of the damage of high pressure eddy current the entrance point inwall; One end of wear-resisting bushing pipe 2 feed liquors has flange; Flange leans against on the end face of nozzle body 1; And compress through lock bolt 4 by pressure cap 3, prevent anti-wearing liner 2 move axially and obscission takes place, after anti-wearing liner 2 damages; Can dismantle pressure cap 3 and change anti-wearing liner 2, thereby prolong the application life of nozzle effectively and improve its operating efficiency.
Claims (1)
