埕海地区一趟管柱分层延迟射孔试油联作技术研究与应用

Research and Application of One-trip String Layered Delayed Perforation and Oil Test Technology in Chenghai Area

通常分层射孔试油联作技术主要被用于多层测试射孔井中,其测试得到的结果都是多层混合的数据,不仅无法准确了解单个层的具体情况,而且还会增大施工成本,引发事故风险,所以必须对其进行改造。由此,本文就提出了一趟管柱分层射孔试油联作的技术,并对其减震、释压、起爆等方面展开了详细的研究,研究结果发现应用一趟管柱分层射孔试油联作技术不仅能对不同层展开分层射孔的实验,而且还能有效增强试油的准确性,减小试油时间,效果极为显著。

Usually,the combined operation technology of multi-layer perforation and oil testing is mainly used in multi-layer test perforation wells,and the test results are multi-layer mixed data,which can not only accurately understand the specific situation of a single layer,but also increase the construction cost and cause accident risk,so it must be reformed.Therefore,this paper puts forward the combined operation technology of onetrip string layered perforation and oil test,and makes a detailed study on its shock absorption,pressure relief and initiation.The results show that the combined operation technology of one-trip string layered perforation and oil test can not only carry out layered perforation experiments on different layers,but also effectively enhance the accuracy of oil test and reduce the time of oil test,with remarkable effect.
