海上油田同心边测边调分层注水管柱研究及应用

摘要

基于陆上油田偏心边测边调技术发展与应用现状,结合海上定向井大排量注水井特点,通过同心边测边调分层注水管柱工艺设计和同心测调仪器与同心测调工作筒的重新设计,形成了一套新型同心边测边调分层注水管柱技术,并在现场应用中取得了良好效果,满足了海上油田大斜度大排量注水井分层注水的需要.%Based on the technical development and application of eccentric test and adjustment in onshore oilfield,a new concentric test and adjustment zonal injection technology has been developed through redesign of concentric test and adjustment string and barrel and combined with the high flow rate in offshore directional injection wells.The field application of the technology has given good result and met the needs of zonal injection of high flow rate and high angle injection wells in offshore oilfield.
