摘　　要：冀东油田高浅北区为一整装的常规稠油油藏,区块含油面积大,边底水活跃,依靠天然能量进行开发。因区块油水黏度比高,储层非均质性严重,油藏表现出边底水突进严重、含水上升快、采收率低的开发特征。近年来,针对油藏特点,大规模应用水平井技术,积极探索并不断完善边水油藏调剖、调驱技术,开发效果明显改善,采收率不断提高。从油藏工程的角度,介绍了水平井技术和边水调剖、调驱技术在高浅北区常规稠油油藏的设计及应用效果。Gaoqianbei Area is a self-contained conventional heavy oil reservoir in Jidong Oilfield,with wide oil-bearing area and active edge and bottom water body.The development of the reservoir depends on natural energy.High oil-water viscosity ratio and strong reservoir heterogeneity cause the irregular coning of edge and bottom water,rapid rising of water cut and low oil recovery efficiency.In recent years,horizontal well technology,profile control and oil displacement technologies of edge water reservoir were applied to the reservoir.The development effect was obviously improved and the recovery efficiency was enhanced continuously.This paper introduces the design and application effect of horizontal well and the profile control and oil displacement of edge water reservoir in the conventional heavy oil reservoir of Gaoqianbei Area from the respect of reservoir engineering.
