摘　　要：高效复合射孔技术将传统的单纯射孔分成三个阶段作业 ,即射孔、清堵造缝、裂缝延伸 ,这三项作业分别由三个独立装药来完成。简要介绍了高效复合射孔技术装药结构和工作原理 ,强调了油层孔道内随进装药二次爆炸的优点及作用。Effective composite perforating technology is a new method,which will have a enormous economic benefit and wider marketable prospect.It divides traditional perforating operation into three stages,which are perforation,pollusion removal,formation fracturing and fissure extension.These works are accomplished by three independent charges separately.This paper describes the charge structure and the principle of the effective composite perforating technology,emphasizes the advantage and effect of the second explosion of the charge followed the jet into the hole which is perforated by the shaped charge.
