Abstract

The utility model provides a high pressure resistant no body perforating bullet of low jump ring formula, relate to the manufacturing technical field of high pressure no body perforating bullet, which comprises a housin and lid, the lid surrounds in the lower half outside of shell case, set up the sealing member between lid and shell case, it is fixed to set up the spring card between lid and shell case and be connected, adopt low piece casing and lid, and the mode that the jump ring is connected, a low piece jump ring formula that has high penetrability has been designed, it is great to have avoided steel shell case bullet explosion back piece, cause the problem of sticking well, it is little to have the piece after the perforation, no sharp edges and corners, be convenient for circulate and take out the characteristics of well head.

Description

Clamp spring high-pressure resistant body-free perforating bullet
Technical field:
A kind of clamp spring high-pressure resistant body-free perforating bullet, be applicable to tap the latent power in old well or old stratum and the perforation through tubing on new well or new stratum, relates to the manufacturing technology field of high pressure body-free perforating bullet.
Technical background:
In existing oil gas field, owing to having part producing well newly developed or original old well to use the oil pipe that interior latus rectum is less, therefore, at Xin Jing, put into production or old well reform when volume increase, just need to carry out the perforation of oil pipe, this perforation of crossing oil pipe just needs to use body-free perforating bullet; The steel shell case used at present is without body of a gun perforation through tubing bullet, due to what use, it is the steel shell case, so the chip after the perforating bullet blast is larger, these larger chips can cause the situations such as chip or perforator Ka Jing, when the card well occurring, due to Oil/gas Well under the penetration of perforating bullet, oil-gas Layer is opened, so, although after the perforating bullet blast, larger chip has caused the situations such as Ka Jing, but down-hole still can be with certain pressure, the pressure of these down-holes can be processed and bring a lot of risks follow-up engineering accident.
Summary of the invention:
The present invention be directed to the defect of prior art, the mode that adopts after blast the material that only produces low-debris to be connected with jump ring, designed a kind of clamp spring high-pressure resistant body-free perforating bullet with high penetrating power.
The present invention is achieved in that a kind of clamp spring high-pressure resistant body-free perforating bullet, comprise housing and lid 6, housing comprises shell case 1, explosive 2 and cavity liner 3, explosive 2 is arranged between shell case 1 and cavity liner 3, lid 6 is enclosed in the Lower Half outside of shell case 1, be provided with seal 4 between lid 6 and shell case 1, between lid 6 and shell case 1, be provided with Spring Card 5, Spring Card 5 is connected and fixed lid 6 and shell case 1;
Described shell case 1 is to be made by ductile cast iron material;
Described lid 6 is made by ductile cast iron material;
Described seal 4 is " O " RunddichtringOs;
During use, the present invention is arranged on without robbing the body perforation and robs, G.I.H, cause on ground, perforating bullet excited and inject in stratum, completes the perforation construction; In design, body initiation ends flame proof thickness is optimized design, equal energy reliable initiation in the scope of 0.7~1.7mm, and its percentage of initiation reaches 100%; Aspect the cloth bullet, in order to overcome the generation of meeting the card accident after perforation, adopt the position and open butt formula and structure of arranging of stress groove, therefore, after the perforating bullet blast, stress is concentrated, and has reduced the being damaged deformation effect of detonation wave to firing mount, has reduced the chip after the blast.
Useful result of the present invention is: because housing of the present invention and lid are to be made by ductile cast iron material, the chip that ductile cast iron material produces after the perforation blast is less, the chip formed is without obvious sharp corner angle, can take well head out of by the circulation of drilling fluid fully, avoided the engineering accident caused due to chip or perforator Ka Jing, and further dangerous situation, at the sealing ring arranged between housing and lid and linking springs card, make between housing and lid can guarantee effectively to be tightly connected, rotation that can also freedom and flexibility.
The accompanying drawing explanation:
Fig. 1 is cross-sectional view of the present invention.
Specific embodiments:
Provide embodiments of the invention below in conjunction with accompanying drawing: the present invention includes housing and lid 6, housing comprises shell case 1, explosive 2 and cavity liner 3, explosive 2 is arranged between shell case 1 and cavity liner 3, shell case 1, explosive 2 and cavity liner 3 are by pressing the bullet mould under high pressure to press together, lid 6 is enclosed in the Lower Half outside of shell case 1, for the reason sealed, be provided with seal 4 between lid 6 and shell case 1, seal 4 is " O " RunddichtringOs; For realize the blast after low-debris, shell case 1 and lid 6 are made by ductile cast iron material; For shell case 1 and lid 6 are combined, guarantee not only to be connected reliably but also can rotate on freedom and flexibility ground between shell case 1 and lid 6 simultaneously, be provided with Spring Card 5 between lid 6 and shell case 1, realize being connected and fixed between lid 6 and shell case 1 by Spring Card 5, make shell case 1 and lid 6 form complete low-debris without body of a gun perforation through tubing bullet; During installation, first press the bullet mould under high pressure to press together shell case 1, explosive 2 and cavity liner 3 use, then in the seal groove of shell case 1 bottom cylindrical, load onto " O " RunddichtringO, then the lid 6 of making is snapped in to the Lower Half outside of shell case 1;
During use, butt formula and structure are put and opened to perforating bullet of the present invention according to the sticking position of arranging of stress groove to be arranged on without robbing the body perforation and to rob, by the cable G.I.H, until need the layer position of perforation, then by ground, caused, make to be contained in the perforating bullet that perforation robs and excite, inject in stratum, complete the perforation construction of ground, stratum;
According to actual experiment repeatedly, show, the external pressure ability of bearing of the housing of this clamp spring high-pressure resistant body-free perforating bullet and lid is 90MPa, 160 ℃/24h, overcome the impact of in the past due to the perforating bullet that adopts other low-debris materials to cause, wearing dark hydraulic performance decline, when carrying out the test of steel target, its steel target is worn deeply >=98mm, be greater than the requirement of national standard, other performances meet the requirement of GB/T 20488-2006 fully, in design, in order to make percentage of initiation reach 100%, body initiation ends flame proof thickness is optimized to design, make flame proof thickness equal energy reliable initiation in the scope of 0.7~1.7mm, through using proof, its percentage of initiation has reached 100%, aspect the cloth bullet, in order to overcome the generation of meeting the card accident after perforation, adopt the position and open butt formula and structure of arranging of stress groove at this clamp spring high-pressure resistant body-free perforating bullet, therefore, after the perforating bullet blast, can effectively form stress concentration point, reduce the being damaged deformation effect of detonation wave to firing mount, reduce the chip after the blast.
