摘要
为提高不均质油藏注水开发的最终采收率 ,利用反映层状不均质性的二层地质模型 ,对层状砂岩油藏的周期注水开发进行了数值求解 ,研究了影响周期注水效果的主要因素 ,并对注入水的波动幅度和波动频率进行了优选 .结果表明 :地层的非均质性分布状况是影响砂岩油藏周期注水效果的直接因素 .在油田开发实践中 ,为了达到最佳的开发效果 。
In order to improve the final flooding recovery of heterogeneous oil reservoir, the numerical solution to the periodic flooding of stratified reservoir was obtained by using a two-layer geological model reflecting the heterogeneity of strata. Factors influencing the efficiency of water injection were studied. Parameters such as surge range and surge frequency which may affect the flooding were optimized. The result shows that the heterogeneity directly influence the efficiency of flooding. Therefore, it is necessary to determine the optimum parameter in order to reach the best result.
