低渗透油田开发中后期水驱规律及剩余油分布新认识

New Knowledge on Water Flooding Law and Remaining Oil Distribution in the Mid and later term of Lowpermeability Oilfield

新立油田于1983年全面投入开发。当时借鉴扶余油田开发经验,采用注水开发,东西向注水快。近几年通过应用各种先进监测技术,并进行历史注采分析,对油水运动规律取得了新的、系统的认识:传统认为的东西向水线仍具备剩余油。

The Xinli Oilfield was developed in 1983。Adopted water injection for taking example by Fuyu Oilfield.,the water injection rate was fast in east-west at that time. In recent years the new systematic knowledge of regular pattern of oil and water's motion was acquired through various advanced monitoring technology and analyzing the historical injection. There are still remaining oil in east-west line traditionally
