Abstract
The utility model discloses a pressure detonator of a full bore perforation of an oil-gas well, aiming at solving the problem that the existing detonator can not form a channel for following operation after detonation. The pressure detonator comprises a joint, a detonation joint, a detonation core and an outer sealing ring, wherein the joint is connected with the detonation joint; the center of the detonation joint is provided with the detonation core; the detonation joint is internally sealed with a pressure core part which is sealed with a pressure striker seat; the pressure striker seat is internally sealed with a pressure striker; a pressure pin is arranged between the pressure striker seat and the pressure striker; a continuous detonation pipe is connected below the detonation core; and a plugging cover is arranged below the continuous detonation pipe. The pressure detonator realizes detonation function, simultaneously completes size degradation of internal members and achieves the purpose of internal smoothness.
Description
Technical field
The utility model relates to the full aperture perforation pressure detonator that a kind of perforating oil gas well is used.
Background technology
But after detonating, existing priming device can't form the passage of subsequent job.
The utility model content
The purpose of this utility model provides a kind of oil gas well full aperture perforation pressure detonator, but to solve the problem that can not form the subsequent job passage that existing priming device exists.
The utility model comprises joint, priming adapter, detonating core, exterior seal ring, joint links to each other with the priming adapter sealing, the priming adapter center is provided with detonating core, be sealed with the pressure chipware in the described priming adapter, the pressure chipware is sealed with the pressure striker post, is sealed with the pressure firing pin in the pressure striker post, is provided with press-on pins between pressure striker post and the pressure firing pin, be connected with continuous booster under the described detonating core, continuous booster has blanking cover.
The utility model is controlled Initiation Pressure by configuration press-on pins quantity and specification, utilize the detonating core energy to realize the propagation of detonation in pressure chipware radial direction, for the internals size degradation provides energy transmission path, finish the internals size degradation when function is detonated in realization, reach inner unobstructed purpose.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model comprises joint 1, priming adapter 7, detonating core 6, exterior seal ring 81, joint 1 links to each other with priming adapter 7 sealings, priming adapter 7 centers are provided with detonating core 6, be sealed with pressure chipware 2 in the priming adapter 7, be sealed with pressure striker post 3 in the pressure chipware 2, be sealed with pressure firing pin 4 in the pressure striker post 3, radially be provided with 1～24 press-on pins 5 between pressure striker post 3 and the pressure firing pin 4.By adjusting the control that press-on pins 5 quantity and specification realize Initiation Pressure.Detonating core is connected with continuous booster 9 for 6 times, and continuous booster 9 has blanking cover 10, is provided with explosive in the blanking cover 10.Utilize the detonating core energy to realize the propagation of detonation, for the internals size degradation provides energy transmission path in pressure chipware radial direction.
Each seals the position: be equipped with the sealing ring 82 that some matches between joint 1 and the priming adapter 7, between priming adapter 7 and the pressure chipware 2, between pressure chipware 2 and the pressure striker post 3 and between pressure striker post 3 and the pressure firing pin 4.
The utility model action principle:
The utility model pressure detonator is contained in perforating job tubing string end, controllable pressure acts on the pressure firing pin 4 from joint 1, when controllable pressure is elevated to the withstand voltage limit of all set pressure pins 5, press-on pins 5 is sheared, pressure firing pin 4 descending and impact initiation cores 6, detonating core 6 detonates, detonation wave is ignited the explosive that is arranged in pressure chipware 2 and the continuous booster 9 simultaneously, explosive in the explosive initiation blanking cover 10 in the continuous booster 9, utilize detonating core 6 and be arranged on pressure chipware 2, the detonation energy of the explosive in continuous booster 9 and the blanking cover 10, add the pre-ceasma 11 and the presplitting groove that itself are preset on each internals, realize the internals size degradation, chip falls, and reaches inner unobstructed purpose, and the detonation energy of the explosive in the blanking cover 10 is enough to realize the function of detonating of this device simultaneously.
