高压井测试中MFE开关井操作问题探讨

Discuss on Opening and Closing Operation of MFE in High Pressure Well.

通过对MFE测试器的结构原理以及与P-T和RTTS封隔器组合时在高压油气井测试中的受力分析,系统阐述了MFE测试器在高压油气(包括高压、低渗)层测试中开不了井的原因,通过典型实例验证了该观点的客观性,同时提出相应的解决办法。

By analyzing structure principle of MFE tester and force of combination of P-T and RTTS packer using in high pressure oil well,the reason of MFE tester can not being opened in high pressure oil & gas layer(including high pressure and low percolation layer) is illustrated systematically.And by typical examples,the objectivity of these notes has been tested and corresponding method is suggested.
