示踪剂检测法在双1井的应用

APPLICATION OF TRACER DETECTION METHOD IN THE WELL SHUANG-1

随着气井开采进入后期,气水同产井越来越多,了解气水同产井间的连通关系就显得越来越重要,而示踪剂检测法就是一种操作简单、成本低、结果可靠的方法。为此介绍了气水同产井双1井与地层水回注井双9井间的连通关系,采用了示踪剂检测法,证明了双1井与双9井虽然产层不一样,但层间连通,从而弄清了气水同产井双1井开采越来越困难的真正原因,为下一步双1井采取合理的开采方式提供了新的思路,对于指导生产具有指导作用。同时通过该方法在双1井与双9井的现场成功运用,也为气水同产井证明井间连通关系找到了一种简单易行的方法。

With the arrival of gas well anaphase exploitation,gas water wells appear more and more consequently,and to investigate the connected relationship of gas water wells becomes more and more important.To investigate,an easy,cheap and simple method for performing is tracer detection.Therefore,the connected relationships between the gas water well Shuang-1 and the formation water re-injection well Shuang-9 are introduced.By using the tracer detection method,it is proved that although the wells of Shuang-1 and Shuang-9 have different pay formations,their formations are connected.Thereby,the real reasons for the increasingly difficult exploitation of gas water well Shuang-1 are identified,which provides a new way of thinking for the next step to take the reasonable exploitation that has the guiding role in direct production.This method has been successfully applied in the wells of Shuang-1 and Shuang-9,which attests that it is a simple and practical way to prove the inter-well connected relationships for the gas water wells.
