摘　　要：在射孔的同时,利用射孔枪内的可控固体火箭推进剂爆燃产生的高能气体对射孔地层进行压裂,可使目的层形成拉链式的裂缝,提高井筒附近的渗透率;同时,负压冲击得到较深而干净的射孔孔眼无射孔损害,大大降低了流体流入井筒的阻力,提高了油井生产率。A new fracturing technology and a negative impact mechanism has been introduced. The new fracture technology concurrent perform with perforating operation and its mechanism lie in that it use high energy gas that the production when the control solid socket was exploded. This technology used to fracturing work will make a zigzag gap in the target formation and can also improve the permeability in the vicinity of well bore. And then, the negative pressure impact technology has been analyzed, it make no damage to the deeper and clearer perforation and reduce the friction caused when the fluid s flow into well bore.The two technologies are very efficiently,usefully and costly for oil wells.
