摘要
随着国内外水平井的大量应用及其严重产水现象的出现,水平井堵水技术越来越受到广泛重视,有必要对水平井堵水技术进行梳理和总结。综述了油藏研究、测井找水、堵水剂和堵水工艺等水平井堵水技术目前在国内外研究与应用的情况。通过分析水平井堵水技术现状,总结出各项技术均存在一定问题,并确定了其下步发展方向。认为油藏工程、选择性堵水剂和选择性堵水工艺是水平井堵水技术研究的重点,笼统注入选择性堵剂的堵水技术更适合在海上油田应用。
With the large number of applications of horizontal wells,water shutoff for horizon- tal well is attracting more and more attentions.It is necessary that summarize this technology. Reviewed is the technology progress of water shutoff for horizontal well,including product water principles,water plugging agent and plugging proeess study. Through the analyzing, find the problems and development directions of water shutoff for horizontal well. It is point- ed out that the focus of water shuroff technology are reservoir engineering,selective agent and selective process.It is appropriate technology of water shutoff for horizontal well on offshore oilfield that selective agent is used in commingled water shutoff process.
