环空测井找漏工艺研究与应用

Research on and application of the leakage location technology in Annulus logging

文章介绍了基于井筒、地层复杂状况及锁作业现场需要,研究应用环空测井找漏施工工艺,可以有效降低作业成本,缩短施工占井周期。还可根据实际情况,在注入剖面和产出剖面两种状态下测量,找漏结果更加真实可靠。该方法在FU124等井成功应用,并取得了较好效果。

Based on the wellbore,complex formation condition and operation site,construction technology of annulus logging for leakage is studied and applied.On the One hand,the cost is reduced effectively,and the construction period for well is shortened.On the other hand,the injection profiles and production profiles is measured in two state,so the results are more reliable to locate leakage.The method was applied successfully in FU124 well and achieved good re-sults.
