摘要(Abstract):
注水开发油田,每个开发阶段技术政策不同,配套工艺技术也不相同。目前,萨中地区萨葡油层老井已进入高含水后期。针对开发中出现的具体情况,将部分分层注水井改为笼统注水,取得了较好的效果。本文用实例阐明了这种效果及实现的条件。
During oilfield development by water flooding, at each development stage, the technical policies are different, and so are the complete sets of technological requirements. Today, some old wells in Saretu and Putaohua formations, central Saretu area have already entered the high water-cut late stage. In view of the practical conditions encountered during development, better results have been obtained by changing some of the wells produced by separated-layer water injection to multi-layers water injection. Examples are incorporated in the paper to show the results and conditions.
