摘要: 提出了一个适合于研究非均质油藏周期注水渗流机理的数值模拟模型,将微观剩余油储油
可流动空间列为第二级渗流系统,采用两套空间重叠的网格描述油藏的非均质性。运用该模型模拟计算油水驱替运动过程,对比分析影响周期注水效果的油藏地质因素和人工注水方式参数,研究周期注水的驱油机理及适宜采用周期注水的油藏条件和合理的注水方式参数,为周期注水的决策及方式参数的优化提供参考

Abstract: in this paper, a numerical model for the cylic water flooding in the heterogeneous reservoir is founded by studing it‘s seepage mechanism. The store room for the residual oil seepage in microcosmic is named the second seep sys-tem. Two series of block system lapped in space is applied to describe theheterogeneous of reservoir.The corse of water displacing oil is simulated with this model, and some factors that effect the cyclic flooding, such as the geo-logical and manual are analysised by contrsting. It is suggested to make policy and optimize manual means that the mechanism of water displacing oil in the course of cyclic flooding and the best conditions and manual means in reservoir.

Key words: Heterogeneous reservoir, Cyclic injection, Numerical simulation, Mechanism, Seepage evaluation
