摘要： 讨论了各种高能气体压裂方案，提出并实施了破碎燃烧无壳高能气体压裂技术，压裂井深1000～5000m，在5ms内p-t曲线升至最大，作用时间在700～2000ms内可调，实现了多缝起裂，长时延缝的设计思想。该技术简单、可靠，增产效果显著，有很大的推广应用价值。

Abstract: The authors discussed different types of high energy gas fracturing techology,designeda crack combusting caseless high energy gas fracturing device and put it into effect. The fracturingdepth varies from 1000 to 5000m. In 5ms the pressure comes to maximum. The working time can beadjusted from 700~2000ms. So multi-crack fracturing and long time crack-extending can beacquired. This technology is very simple and reliable, and production increasing is very remarkable.It will be applied expansively.
