| 摘 要： | 中高含水期开发阶段，稳产难度越来越大，稳油控水成为主要任务．地层压力保持水平是实现稳油控水的一个关键因数，为此，应用物质平衡方程和水驱特征曲线，研究了合理注采比，地层压力保持水平及产液量和含水率之间的定量关系，并以别古庄油田京１１断块为例给出了应用结果，该方法对于确定高含水期开发阶段油田的注水政策有一定的指导意义和实用价值．

| Abstract: | Most of the oilfields in east China have been in middle or high watercut stage.To maintain a
stable oil producion and control watercut becomes a main task of oilfield engineers.Maintaining
formation pressure level is a key to finishing the task.The quantitative relationships between
injectionproduction ratio.formation pressure level and fluid yield and watercut are obtained by
material balance equation and waterdrive characteristic curve,and they are applied in Jing11
fault block of Bieguzhuang Oil Field.The research result is of importance in making water
injection policy for high watercut oilfields. |
