燃气式超正压射孔技术研究

Study on Combustion-gas Ultrapositive-pressure Perforating Technique

对燃气式超正压射孔技术利用火药燃烧产生的能量与射孔充分结合增加原油产量的原理进行了探讨和研究 ,并对该技术的结构包括升压系统、火药的用药量、延时起爆器等部分进行了合理的设计 .该技术在现场试验获得成功 。

This technique is actually the combination of high energy gas fracturing and perforating, and the pressure produced in wellbore when explosive burns is much higher than formation fracture pressure. So a good fracturing result can be obtained. The principle of the technique is introduced, and the pressure-increasing system, explosive load, delay-time primer detonator etc. are designed. The application of the technique to Zhongyuan Oil Field shows that it is a better well-completion and production-increasing technique.
