生产油管找漏技术在海上油田的应用研究

Research and application of offshore oil field in production tubing leak detection technology

针对于海上油田的电潜泵油井在生产油管出现破损泄漏而导致产液量急剧下降或关停现象,本文通过一系列研究分析,引入噪声辅助流量的测井作业方式,可实现在生产油井的油管破损泄漏点精确定位;并通过海上某油田现场实际应用,成功实现了破损点位置确定,为该井的下步方案提供了措施方向。

In view of the phenomenon that the liquid production of the electric submersible pump oil well in the offshore oil field is sharply reduced or shut down due to the leakage of the production tubing,this paper introduces the logging operation mode of noise assisted flow through a series of research and analysis,so as to realize the accurate location of the tubing leakage point of the current production oil well.Through the practical application in the offshore oil field,the location of the damage point is successfully determined,and it provides the measure direction for the next plan of the well.
