摘要
通过对内置式、袖套式、对称式和下挂式四种不同类型复合射孔器的设计结构、作用原理及安全性对比分析,建议根据不同井身结构、地层污染程度等情况,合理设定峰值压力及火药用量,在确保作业安全前提下,优选高效复合射孔器。
By analyzing and comparing the structure,principle and safety of four different types of perforators,i.e.built-in style,oversleeve-style,symmetry style and hanging style perforators,a method of optimizing effective composite perforation by correct determining peak value of pressure and amount of gunpowder,under the precondition of operation safety,according to the hole structure and formation damage is proposed.
