摘　　要：针对海外河油田注水开发中存在的问题,结合油田开发现状,提出了"注堵调"一体化技术思路。即以注采井组为单元,将油水井压裂解堵、分层注水、深度调剖、化学堵水等技术进行优化整合,最大程度地发挥技术整体作用,提高注采井组采收率。经现场应用取得了良好效果,使油田连续3 a日产油保持在1 000t/d以上,实现了油田的高效开发。The technology of integrated injection - plugging - profile control has been proposed for Haiwaihe Oil- field in accordance with the problems occurred during water flooding.With well group as flooding unit,the tech- niques of fracturing and block removing,stratified waterflooding,in- depth profile control,and chemical water plugging for oil and water wells are integrated and optimized to improve recovery factor.Field application has seen good result,daily oil production has sustained over 1 000 t/d for 3 years,thus realizing efficient develop- ment of the oilfield.
