Description

On-site zero wiring device of perforating gun

Technical Field

The utility model relates to the field of perforating guns, in particular to a field zero wiring device of a perforating gun.

Background

In the oil and gas exploitation process, a casing is usually put in after drilling, cement is injected for well cementation, and after well cementation, a connecting passage between an oil and gas layer and the casing is opened through perforation and fracturing operation. The bridge plug and perforation are combined to be the most widely used perforation completion mode for unconventional oil and gas reservoir development, and the single well yield can be effectively improved.

The perforating tool string carries a plurality of perforating guns lowered into the cased well at the location of one or more hydrocarbon reservoirs in the subterranean formation. The perforating gun is internally provided with the shaped perforating charges, and the shaped perforating charges are sequentially ejected through the perforating gun barrel, the sleeve and the cement pouring layer after being initiated, so that hydrocarbon can flow into the sleeve. Once the perforating gun reaches a specified position, a ground instrument sends down an ignition signal and a selective firing switch to detonate a detonator in the perforating gun, and then a detonating cord is ignited, and the detonating cord detonates the shaped perforating bullet to penetrate a gun barrel, a sleeve and a cement layer, so that stratum fluid flows into a production pipe; when a wired detonator is used, it must be manually connected to an electrical connection, which can cause a number of problems. Because the parts are rotationally assembled, the wire may wear, kink, fold or crack, and manual wire bonding is prone to rework.
