Abstract

The invention provides a contact type perforating gun, and relates to the technical field of petroleum drilling. The contact type perforating gun comprises perforating gun barrels (1), perforating gun connectors (2) and positioning discs (4); each perforating gun connector (2) is arranged between every two perforating gun barrels (1), and the two ends of each perforating gun connector (2) are connected with the corresponding perforating gun barrels (1) respectively; the positioning discs (4) are installed and fixed on the perforating gun barrels (1) and are positioned on the connecting end surfaces between the perforating gun barrels (1) and the perforating gun connectors (2); wire passing devices (3) are arranged in the perforating gun connectors (2); wire passing connectors (5) are arranged between the wire passing devices (3) and the positioning discs (4); and the wire passing connectors (5) are installed and fixed on the positioning discs (4) through buckles. According to the invention, the wiring operation among the multi-stage perforating gun barrels can be simplified, and the technical problems of low wiring efficiency among perforating guns and limited wiring operation space are solved.

Description

technical field [0001] The invention relates to the technical field of petroleum drilling, in particular to a contact type perforating gun. Background technique [0002] In oil and gas well cable multi-stage perforating operations, the multi-stage perforating string used is used as a perforator. After this type of device is lowered into the bottom of the well, it is powered by the ground to activate the electrified detonator, ignite and detonate the perforating charge, and pass through The armor-piercing effect of the perforating bullet penetrates the casing and the formation to form oil and gas channels; the multi-stage perforating string has built-in multi-stage connected perforating guns, and the upper end of each stage of the perforating gun needs to be equipped with an ignition device ;In the conventional multi-stage perforating string, including the outer gun barrel, bullet holder tube and connecting joints, the user needs to open the perforating gun and connect the le...
