Product Details

Perforating guns

Perforating guns are applicable to perforation in complicated sections in deep wells, highly-deviated wells, horizontal wells, directional wells, etc., and can also operate together with formation testers.

CONVENTIONAL PERFORATING GUNS

Conventional perforating guns include eight series, 30 items and 26 kinds of matched downhole tools.

Gun body with blind hole is made by high strength alloy steel and its features are high strength, high toughness, no crack and less deformation after releasing.

MAIN AUXILIARY TOOLS OF PERFORATING GUNS

Annulus negative pressure perforating device: It's a tool firing the gun by annulus pressure and applicable to not only straight and horizontal wells, but also perforating operation in viscous oil wells, as well as high temperature and pressure wells.
