摘要(Abstract)：
针对萨北开发区油层沉积特点及特高含水期剩余油分布特点,以水动力学原理为指导,对以往周期注水的效果进行分析,在已有的实践经验基础上,结合数值模拟研究,优化周期注水方式及各项参数,引入了油井间歇采油改变液流方向改善开发效果的做法,在实践中取得了较好的效果。
Aiming at the remaining oil distribution in ultra-high water cut stage and oil layers depositional features in the north of Saertu oilfield, guided by the hydrodynamic principle, and based on the practical experience and analysis of cyclic water flooding in combination with numerical simulation, cyclic water flooding and various pa- rameters are optimized, intermittent production of oil wells to change fluid direction is adopted so as to improve the development effect which has acquired favorable result in the test area.
