摘　　要：在多层需要测试的射孔井中,一般采用分层多趟管柱射孔测试联作或一趟管柱对几个临近的层进行射孔后多层混合测试,致使测试结果为多层混合数据,不利于对单个目的层准确认知,同时增加成本和造成工程事故的风险。给出一趟管柱分层射孔试油联作工艺的设计原理,从减震、压力释放、起爆等多种方式及安全性能进行全面分析。采用一趟管柱分层射孔试油联作,可实现对不同目的层进行一趟分层射孔和测试,提高试油准确性及缩短试油周期,降低工程事故率。In multi-layer tested perforated wells,we often use perforating and testing combination by hierarchical multiple trips strings or multi-layer mixed tests are made in several adjacent layers perforated by a trip string,so,test results are multi-layer mixed data,it is not conducive to accuratly recognizing single target layer,but increases costs and risk of engineering accidents.We propose design principle of stratification perforating and oil test combination technology by a trip string,comprehensively analyze detonating manners and its safety performance,such as,shock absorption,pressure release,etc.So,different target layers can be perforated and tested by a trip string to improve the accuracy of the oil test,shorten the oil testing period and reduce the rate of engineering accidents.
