Abstract

The invention discloses a novel and simple clustering selective perforator convenient to assemble. An internal thread I (5) and an internal thread II (6) are arranged on the inner wall of the left endpart of an outer barrel (1); an internal thread A (7) is arranged on the outer wall of the right end part of the outer barrel (1); the perforator further comprises a lower positioning disc component(8) and an upper bearing disc component (9); the lower positioning disc component (8) comprises a lower positioning disc (10) and an ignition module (11); the ignition module (11) comprises a column body (12) and a detonator (13); a blind hole A (14) and a blind hole B (15) are formed in the lower end part of the column body (12); a pin base A (16) and a pin base B (17) are respectively in interference fit with the blind hole A (14) and the blind hole B (15); a spring wire through column (19) is glidingly mounted in a small hole of a stepped hole (18). The perforator has the beneficial effectsthat the structure is simple, the connection workload is reduced, the on-site operation difficulty is reduced, the on-site assembly technology is simplified, and the safety is improved.

Description

technical field [0001] The invention relates to the technical field of the structure of the cluster-selecting emission hole, in particular to a novel cluster-selection emission hole that can be assembled easily and quickly. Background technique [0002] The perforating gun is an indispensable and important device in oil exploitation. The perforating gun includes an outer gun barrel, a bullet holder tube and a positioning plate. The bullet holder tube is fixed in the outer gun barrel. There are multiple installation holes arranged on the bullet holder tube and along its length. The installation holes are spirally distributed on the bullets. On the frame tube, a perforating charge is installed in each mounting hole, and a detonating wire is wound around the charge frame tube along its length, and each perforating charge is connected with the detonating wire. When working on site, workers need to connect multiple perforating guns in series, and at the same time ensure that the...
