浅谈选择测试阀在浅海海域地层测试中的应用

A Brief Discussion on Application of the Selective Test Valve in Well Testing at the Shallow Waters

选择测试阀作为新一代的全通径测试器,具有灵活可靠、操作简便、成功系数高等优点。但最近几次的浅海海域测试施工中,选择测试阀某些部件损伤、某些测试过程出现开关井失败或延迟开关井现象。现结合实际井例,将其可能形成的原因进行剖析,旨在解决问题,保证施工成功进行。

The Selective test valve is a new generation of full diameter tester,which has advantages of being flexible and reliable,simple operation,and high success factor.But in recent operations at the shallow waters,some parts of it are damaged,and phenomenon of failure or delay of opening or closing well appears.Combining with actual examples,the possible reason is analyzed,aiming to solve the problem,ensure the operation to be successful.
