油田开发进入特高含水期后,开发难度加大,剩余油分布复杂,同时还存在严重的无效循环注水,为此,本文分析归纳了特高含水期油田开发规律,针对层内、层间不同形式的剩余油分布,依据水驱精细开发研究成果,从而采取了有针对性的调整措施,取得了良好的开发效果。
After the development of ultra-high water cut stage, the oilfield development is more difficult to develop and the remaining oil is complicated to be distributed. At the same time, there is still serious invalid circulation waterflooding. Therefore, this article analyzes the law of oilfield development in the ultra-high water cut stage, The remaining oil distribution, according to the water flooding development of research results, which took a targeted adjustment measures, and achieved good development results.
