临盘油田不同类型复杂小断块油藏提高采收率方法研究

Study on Method of Enhanced Oil Recovery in Different Types of Complex Small Fault Block Reservoirs in Linpan Oilfield

临盘油田发育各种不同类型的复杂断块小油藏,经过多年的勘探开发,目前已进入高含水期,传统的笼统注水驱油模式已经不适应高效开发的需要,因此,为进一步提高不同类型复杂断块油藏的采收率,采油厂按照"一类一法,一块一案"的原则,以层系块为对象,以"三提高"为目的,针对不同类型油藏的重点潜力方向,采取相应的技术对策分类治理,逐个断块进行层系及注采井网方案优化,优化到单井、单个措施,同时油藏、工艺、地面一体化同步配套,取得了良好的开发效果,具有很好的推广价值。

The Linpan oilfield develops various types of complex fault block reservoirs.After years of exploration and development,it has entered a period of high water cut.The traditional general water flooding mode has not been adapted to the needs of efficient development.Therefore,it is further developed.To improve the recovery of different types of complex fault block reservoirs,the oil production plant follows the principle of “one type,one method,one case,one block,Focus on the potential direction,adopt corresponding technical countermeasures to classify and control,optimize each layer and injection-production well pattern program one by one,optimize to single wells and individual measures,and at the same time synchronize the matching of reservoirs,processes,and ground,and obtain good results.The development effect has very good promotion value.
