High temperature pressurization device used for propagation of explosion of oil and gas well interlayer

Abstract

The invention discloses a high temperature pressurization device used for propagation of explosion of an oil and gas well interlayer. A connector and a body are fixedly connected by adopting a screw thread, a through bulkhead ignition component is placed in a through hole of the connector, a gunpowder component and a piston component are respectively arranged at the two sides of a combustion chamber of the body, a pressure release valve is arranged on the side surface of the combustion chamber of the body, the body and a first coupling are fixedly connected by adopting an oil tube thread, and the first coupling, a second coupling and a third coupling are connected by adopting a certain quantity of oil tubes. The high temperature pressurization device disclosed by the invention can be used for solving the problem of the propagation of explosion of an interlayer in highly-deviated well and horizontal well multilayer-section and large section distance perforation construction, detonation waves produced after normal initiation of explosion of the upper level perforating gun is utilized to act on a through bulkhead initiator, then the gunpowder component is ignited, and high temperature and high pressure gas is instantaneously produced in the combustion chamber of the body, so that the piston component in the body is pushed out at a high speed; and by virtue of clean water well control fluid in a compressed interlayer oil tube, gas pressure is instantaneously transmitted to the next level pressure type explosion initiation device, and the next level perforating gun explosion initiation operation is completed.

Description

technical field [0001] The invention belongs to the technical field of oil and gas well perforation, and mainly relates to an oil and gas well (TCP) tubing transmission perforation interlayer detonation technology, in particular to a high-temperature booster device for oil and gas well interlayer detonation transmission. Background technique [0002] In the petroleum industry, oil well perforation operation is an important process, which is to lower the perforating gun into the target layer in the well, use the detonating device to detonate, and after detonation, the shaped charge will penetrate the perforating gun, casing and cement layer. The exit channel connects the stratum with the oil well, so that the formation oil and gas can flow into the oil well smoothly. [0003] Multi-stage perforation technology refers to the perforation technology that penetrates multiple oil and gas layers at one time in the case of the next pipe string, which can reduce the number of perfora...
