老井复查试油工艺技术在吐哈油田的应用

Application of Counter Check Testing Technique for Old Wells in Tuha Oilfield.

老井、疑难地层复查试油前必须进行特殊处理作业 ,吐哈油田在实践中初步形成了一套老井复查试油工艺技术 ,包括钻塞、封堵、打捞、固井、浅层测试、探边测试、油气层改造等 ,先后对15口老井 2 4个地质层进行了复查试油 ,均获得了新的发现。

Special operation should be anticipated to reexamine and test in ol d well and difficult question layers.It is formed a series of countercheck tech nique in old well testing,which includes drilling,plug,fishing,cementing,testing of shallow layer,well limit testing,fracture,etc.That having done in 15 old wel ls and 24 geologic formations early or later all have got the new findings.
