Axial action jet torpedo

The equipment is designed to make a directed explosion to destroy foreign metal, bits and their parts, couplings, wedges and other objects that impede the drilling process.

The elements that cannot be removed and interfere with further passage of the drill (metal, bits and their parts, couplings, wedges and other objects) often remain in the well during the drilling process. Axial action jet torpedoes are used to eliminate such elements.

The purpose of the equipment is to eliminate obstacles in the way of the drill head or pipe and clear the well. The torpedoes are also used to eliminate the consequences of accidents at hydrocarbon fields and to restore wells. The torpedo has a streamlined shape, contains a fuse and an explosive element.

Advantages of axial torpedoes:

fast and safe elimination of obstacles in wells;
work efficiency improvement and time saving;
reduction of the costs for restoration and repair operations;
clever design ensuring the directional action;
operation at temperatures up to 150°С;
reliable control.

Several sizes of torpedoes are available, they are used depending on the type of an obstacle and the size of clogging. The outer diameter of the equipment varies from 38 to 120 mm.
