摘　　要：本文分析了大庆油田分层开采技术在油田开发中的作用，从分层注水管柱和分层采油管柱的结构、特性及适应条件等方面，叙述了大庆油田机械分层开采工艺的发展。同时，重点介绍了在大庆油田高含水期，为适应开发调整的需要而研制成功的液力投捞细分注水技术和井下开关式可调层机械堵水技术。This paper analyzes the role of separate layer production technology in Daqing Oilfield, describes the development of mechanical separate layer production technology from the structure, property and application conditions of separate layer water injection string and separate layer production string. At high water cut stage, hydraulic pulling and running separate layer waterflooding technology and downhole switch adjustable layer mechanical water plugging technology are developed successfully to face the need of production adjustment.
