Abstract
The utility model relates to an impact type full-path detonating primer, wherein a sealing cover is stuck on the upper end surface of a casing, an upper core forms threaded connection with a lower core, the upper end of the upper core is provided with a lug boss, and the lower end of the lower core is provided with a lug boss. Shoulders are arranged at positions which are arranged on the inner wall of the casing and are butted with the lug bosses, a firing pin is fixed on the upper end surface of the upper core and is provided with a self-destruction material post, the upper core and the lower core are respectively provided with central through holes which are connected, and impact detonators are arranged in the central through holes of the upper and the lower cores. After the detonating primer is ignited and exploded, inner components are all self-destroyed and are communicated with an inner passage of a full-path perforation gun, a tubular post is not repeatedly disassembled, and the operation of following test, etc. can be conducted.
Description
The utility model relates to a kind of initiator, particularly is applicable to all-pass footpath oil tube transmission perforation.
At present, perforation has become a kind of main completion method in each oil field both at home and abroad, gun perforation process mainly contains cable transmission and tubing transmission dual mode, extensive use along with the existing conventional Tubing Conveyed Perforation Technology, with the raising of oil gas well completion to the perforation requirement, can not form the passage of aperture 〉=φ 50 after the existing detonator detonates, not be suitable for all-pass footpath oil tube transmission perforation technology.
The purpose of this utility model just provides a kind of whole self-destructions of back internals of detonating, need not repeatedly play the impacting type all-pass footpath initiator of lower tubular column.
The purpose of this utility model signal realizes like this: a kind of impacting type all-pass footpath initiator comprises sleeve, seal cover, firing pin, self-destruction powder column, impact detonator, shell, goes up chipware, compositions such as chipware down.One end of sleeve is connected with oil pipe, the other end is threaded with the upper end of shell, the lower end of shell is connected with gun barrel, seal cover is bonded on the shell upper surface, last chipware is threaded with following chipware, the upper end of last chipware is provided with convex, the lower end of following chipware is provided with convex, docking location with convex on the outer casing inner wall is provided with shoulder, and firing pin is fixed on the upper surface of chipware, interior dress self-destruction powder column, last chipware, following chipware is respectively equipped with central through hole, and the central through hole of last chipware is connected with the central through hole of following chipware, in the central through hole that impact detonator is arranged on chipware and the central through hole of following chipware.
Advantage of the present utility model: the whole self-destructions of internals behind this initiator ignition and detonation, the passage of initiator inner chamber formation 〉=φ 50 and full aperture perforation rifle internal channel are communicated with, and need not repeatedly play lower tubular column, just can carry out operations such as follow-up test.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, one end of sleeve 2 is connected with oil pipe 1, the other end is threaded with the upper end of shell 11, the lower end of shell 11 is connected with gun barrel 12, seal cover 3 usefulness are acidproof, water, the adhesive bonds of oil is on shell 11 upper surfaces, last chipware 6 is threaded with following chipware 9, the upper end of last chipware 6 is provided with convex 14, the lower end of following chipware 9 is provided with convex 13, on shell 11 inwalls with convex 13,14 docking location is provided with shoulder, like this, can make chipware 6 and following chipware 9 fixed-site, firing pin 4 adopts hang to be fixed on the upper surface of chipware 6, interior dress self-destruction powder column 5, last chipware 6 is respectively equipped with central through hole with following chipware 9, and the central through hole 7 of last chipware 6 is connected with the central through hole 10 of following chipware 9, impact detonator 8 is arranged in the central through hole 10 of chipware central through hole 7 and following chipware.
