BOMCO is the first manufacturing enterprise of perforating guns in China designated by CNPC, and has been awarded with the quality certificate by the Perforating Equipment Inspection Center. The max. pressure of 89mm perforating gun reaches 148.5MPa, and its max. temperature is 190.1, both of which are the highest technical indexes for products of this kind in this industry of China currently.

 

They 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.
