注水井分层启动压力测试管柱的应用

立足胡庆油田现状，针对注水井层间吸水量及分层压力难以定量描述的问题，研制了分层测试管柱，录取不同层段的分层吸水指示曲线、启动压力，判断各小层的动用状况，寻找潜力层，制定出针对性的治理措施，真正实现储层效益最优化。同时介绍了研制的分层启动压力录取管柱和配套工具的结构、工作原理、现场应用情况及取得的认识。

Application of Separated Layer Starting Pressure Testing String in Injection Well

Basing on the present situation of Huqing oilfield,aiming at the question of the injectivity and pressure of separated layer is difficult to definitely describe,we developed the testing string to enroll the injectivity curve and the starting pressure.Thus we can discern the working affair of every layer,search the potentiality and make the corresponding action,really realize the most beneficial result to the reservoir bed.The paper introduces the testing string,the structure,working princuple,field test and the achieved recognization.
