摘要:为评价复合射孔器的作用效果，根据在相同靶体、试验条件下复合射孔器的压裂能力决定作用效果，探讨采用压裂能力指标评价复合射孔器性能的方法。通过对复合射孔器测试技术、复合射孔作用过程、裂缝形成机理和储层对复合射孔器性能的要求等方面进行研究，得到在实验室条件下可以用复合射孔器产生高能气体的有效压力、有效作用时间来评价复合射孔器性能的结论，为建立一套完整的复合射孔器评价体系打下基础。
Abstract:In order to evaluate the working effectiveness of composite perforator, based on the rule that the fracture ability of composite perforator can show the working effectiveness in the same target and under the same experimental condition, how to evaluate the working effectiveness by using fracture ability is discussed. This study includes composite perforator test technology, perforating process, forming mechanism of fracture and the demand of reservoir on the performance of perforators. The studies prove that the fracture ability of composite perforator can be evaluated by the effective pressure and effective working time of high-energy gas produced by composite perforator. The study helps to build a complete evaluation system.
