试井仪器组合验封技术的研究与应用

Combined Well-test instruments used in packer test

文章对传统验封仪在水井验封过程中易出现的几种异常情况进行原因分析,通过观察失败曲线的形态特征,结合验封仪的结构和封隔器的验封原理,针对传统验封仪在现场使用中存在的一些不足之处,通过技术方法上的创新对原有的测试工艺和测试仪器进行改进,通过多参数分析准确获得验封结果,消除了这些影响验封准确性的不利因素,实现高效验封的测试目的。

The reason why traditional process and testing equipments failed in the packer test is analyzed in this paper by observing the characteristics of the failed curves, checking the structure of the testing equipments, and learning the principles of packer test. Through the innovation of technical methods, the existing test process and test instruments were improved, through analyzing more parameters to get ac- curate test results, direct factors influencing the accuracy of the results were eliminated. Finally, the efficiency was implemented in seal testing.
