摘　　要：为使射孔既增加油气产能又能延长油气井使用寿命,引进了袖套式射孔压裂复合技术。该技术是在射孔枪身外套一个推进剂袖套,射孔弹在井底引爆后,产生强大的金属热粒子引燃推进剂袖套,使其在目的层套管内燃烧形成高压,对地层压裂,产生多条裂缝,使射孔压裂同时完成,达到增产增注的目的。A new compound technology called axle box compound perforating and fracture technology has been introduced, the technology can not only increase oil-gas derivability but also prolong the oil and gas well production life. The technology mechanism is that it can add a pusher agent to the outside of perforate gun, and when the perforate bullet is exploded in the well bottom, a large number of metal particles producing in this process will ignite pusher agent. Meanwhile, these particles cause high pressure,and then make formation fractured.The technology can make perforate and fracture at the same time,and also can make the high production,high ejection into reality.
