The paper introduces the principle and the influential factors of broken down of shock wave,the principle of choosing well and formation,and the testing harvest on location.The broken down of shock wave is a method that the shock bomb in the bottom of well ignited by the ground controlling produces the high power shock wave under well which 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...

The paper introduces the principle and the influential factors of broken down of shock wave,the principle of choosing well and formation,and the testing harvest on location.The broken down of shock wave is a method that the shock bomb in the bottom of well ignited by the ground controlling produces the high power shock wave under well which 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 and the blockade.In the vicinity of oil well the radial multi crack system,which isn't controlled by stress,is formed.The system increases the permeable capability of the layer and it obtains the effect of broken down.The factors affecting the effect of broken down consist of boost speed,peak pressure and the lasting time of the pressure platform.We strengthen the work of choosing oil well and sandstone layer on location during operation,refer to the well history,analyze each data of well entirely and decide the scheme of construction work fitly.By means of performance on site broken down of shock wave gets a sound effect on broken down and improvement of percolation near the bottom of well.Particularly it acquires a wonderful broken down effect on the oil well whose output declines because of the pollution in the bottom of well.

冲击波解堵是通过地面控制引燃井下冲击弹 ,在井下产生高能量的冲击波 ,形成高温、高压 时间平区 ,并以一定的增压速度加载于地层 ,平区持续时间长 ,在 1 5~ 2 5s范围 ,将地层及堵塞物压开 ,在近井地带可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、压力持续时间。在现场实施过程中加强选井选层工作 ,查阅井史 ,全面分析井的各项资料 ,合理确定施工方案。通过现场的实施 ,冲击波解堵具有明显的解堵和改善井底附近渗流能力的作用。尤其对固井井底污染造成油井产量下降井 ,解堵效果非常好
