Embodiment Construction

[0021] The technical solutions of the present invention will be further described below in conjunction with specific implementation examples.

[0022] 1. see figure 1 — image 3 , a kind of ultra-high temperature two-way detonator tube for oil and gas wells provided by the invention, it is made up of four parts such as a metal tube 1 with one end open and one end closed, two types of high explosives and a metal cap 4. Two kinds of high explosives A and B are installed in the metal tube 1, and their distribution in the metal tube 1 is as follows: starting from the closed end of the metal tube 1, the first high explosive A, the high explosive B and the second high explosive A are arranged in sequence. . The first secondary explosive A and the second secondary explosive A are equally distributed on both ends of the secondary explosive B. The first high explosive A and the second high explosive A are high temperature resistant high explosives with high shock wave sensitivity, a...

Abstract

The invention relates to an ultra-high temperature two-way detonation tube for oil and gas wells, which comprises a metal tube with one end open, two types of ultra-high temperature resistant explosives are installed in the metal tube, and the explosives at the opening end of the tube are sealed with a moisture-proof metal cap. The invention realizes the dual functions of the ultra-high temperature two-way detonation tube with high detonation sensitivity and strong output capability, solves the problem of bidirectional, safe and reliable detonation transmission in the existing ultra-high temperature oil and gas well perforation; The success rate is high, saving construction cost and construction risk; at the same time, the present invention is convenient and safe in terms of production, transportation, storage and use.

Description

technical field [0001] The invention relates to blasting equipment for oil and gas wells, in particular to an ultra-high temperature two-way detonator tube. Background technique [0002] In energy-focused perforating of oil and gas wells, in order to improve construction efficiency and implement special construction techniques, it is usually required to go downhole with multiple perforating guns (ranging from dozens to hundreds of guns) at one time, and blast multiple target layers at one time. . All the perforating guns are connected in series through the gun joints, often forming a perforating gun string of hundreds of meters or even thousands of meters. Each section of the perforating gun achieves the purpose of perforating by detonating the detonating cord and detonating the perforating charge. However, the detonating cord between two adjacent guns in this perforating gun string is discontinuous, and there is a section in the middle, and the detonation wave of the deto...
