摘要
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,在已有周期注水实践经验的基础上,结合数值模拟进行机理研究,优化周期注采方式及各项参数,引入了分层段交叉注采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 feature in ultra-high water cut stage and oil layers depositional features in the north of Saertu Oilfield, guided by the hydrodynamic principle, based on the practical experience and analysis of cyclic water flooding in combination with numerical simulation, cyclic water flooding and various parameters are optimized, and layered cross injection with changing fluid direction is adopted so as to improve the development effect which has acquired favorable result in practice.
