Bullet compound perforation technology

Bullet compound perforation technology settled the problems existed in present compound perforation such as low utilization of bombing gun and gas, poor gas fracturing preference followed by perforation. Deviating from the other compound perforating technologies with high energy gas fracturing, bullet compound perforation realize near-well fracturing with blast wave caused by blasting bullet explosion in perforating channels. Technological mechanism, characteristics and index of bullet compound perforation technique were illustrated in this paper. The experiment show that the bullet compound perforation technology is valuable to enhance the productivity of oil gas wells, and worth application and popularization.
