摘　　要：通过地面控制引燃井下冲击弹 ,在井下产生高能量的冲击气体 ,形成高温高压气体波 ,并以一定的增压速度加载于地层 ,在 1.5～ 2 .5s将地层的堵塞物压开 ,在近井地带形成多条不受地应力控制的径向多裂缝体系 ,提高地层渗流能力 ,起到解堵效果。经现场实施 ,高能气体压裂具有明显的解堵和改善井底渗流能力的作用。尤其对井底污染造成油井产量下降井 ,解堵效果更好。The high power gas fracture is a method that the shock bomb in the bottom of well is ignited by the ground controlling produces and the high power shock wave under well forms a high temperature/pressure-time platform acting on the stratum with a certain boost speed.The platform continues for a long time,in 1.5～2.5 s,and breaks down the formation.In the vicinity of oil well,the redial multi-crack system increases the permeable capability of the layer and obtains the effect of broken down.By the performance on site,it has a function of improvement to percolation near the bottom of well and particularly acquires a wonderful broken down effect in the oil well,which output declines because of the pollution in the bottom of well.
