Embodiment 1

[0036] Embodiment 1, safe detonation method, the steps are as follows

[0037] A. Assembly: First, use the existing special tools to install the reverse sealing device 9 and the explosive transmission device 8 with energy-gathering holes into the bottom of the explosive joint 6, then install the miniature detonating device 7, and finally install the forward sealing device in sequence Device 5, percussion device 4, percussion device protective cap 3, have so just formed a complete safe sealing detonation device.

[0038] B. Remove the protective cap of the firing device: transfer the safety sealed detonating device to the detonation destination, and remove the fishing head (31) on the protective cap of the firing device with the existing special tool;

[0039] C. Detonation: After the removal is successful, hit the triggering device 4 with a special impact tool, the triggering device 4 triggers the miniature detonating device 7, the detonating device 8 receives the detonation s...

Abstract

The invention discloses a safety sealed detonation device and a safety detonation method, belonging to the construction field of oil-gas well perforating operation and building foundation pit blasting, and aiming to solve the problem that the traditional detonator cannot realize integrative sealing. The device comprises a detonation device lifting pipe fitting, a pressure relief and chip removal hole, a positive sealing device, an explosion joint, a firing gear crash helmet, a firing gear, a miniature detonation device, a detonation propagating device and a negative sealing device, wherein the miniature detonation device and the firing gear are arranged on the detonation propagating device in order; the firing gear crash helmet is buckled on the firing gear, and the positive sealing device is arranged between the firing gear and the explosion joint; the detonation propagating device comprises a detonation propagating shell, a booster primer and an energy cavity, the energy cavity is positioned in the bottom of the detonation propagating shell, and the booster primer is arranged in the detonation propagating shell. The device self is wholly sealed, can still keep good leakproofness and detonation capacity in the under environment, and is not easy to be affected with damp and lose efficacy after meeting water.

Description

technical field [0001] The invention belongs to the fields of oil and gas well perforation operation and building foundation pit blasting construction, and in particular relates to a safety sealing detonation device. Background technique [0002] In the process of perforating oil and gas wells and building foundation pit blasting, the initiation of blasting construction network is one of the most critical links. Without a stable and reliable blasting device, the entire blasting construction operation cannot achieve the purpose of blasting construction. If there is no stable and safe In the process of detonation, there will be insufficient detonation energy, failure of the pressure-resistant seal, causing explosion failure and rejection, resulting in failure or accidents in the detonation operation. Only by using a safe and reliable detonating device to excite the detonated and detonated components, can the perforating projectiles, synergistic charges, detonating cords, secon...
