不动管找堵水研究及在文南油田的应用

针对文南油田油层非均质性严重，高渗透层无水采油期短，油井采出程度较低的开发状况，研究和应用了不动管找堵水管柱，实现了不动油管进行找堵水、调层生产。在文南油田应用36口井，累计增油8625t。结果表明该管柱找堵水准确、可靠，经济效益显著。

Study and application of motionless water detecting and plugging string in Wennan oilfield

Reservoirs in Wennan oilfield are highly heterogeneous, the water-free production period of highly permeable reservoirs is short, and the producing degree is low. Motionless water detecting and plugging string has been developed and applied to detect and plug water and to adjust pay horizons without moving of tubing. This has applied in 36 wells in Wennan oilfield with cumulative oil increment of 8 625 t. The result shows that this string is accurate and reliable for detecting and plugging water and has achieved remarkable economic benefit.
