| 摘 要： | 为了给砂岩非均质油藏进一步开展周期注水矿场试验或工业性开采提供依据，利用三维三相黑油模拟器和准两层地质模型进行了垂向非均质砂岩油藏周期注水开采数值模拟研究。通过研究各种地质因素及开发因素对周期注水效果的影响程度，得出周期注水改善非均质砂岩油藏开发效果的主要作用机理为：周期注水产生了层间压差及弹性力的作用，活化了毛细管力和重力的作用，使高、低渗透层之间产生了油水灾渗效应。并得出当垂向渗透率Kv与水平渗透率Kb的比值增大时，周期注水效果先是变好，但到某一值后，其效果又开始变差的与前人不一致的结论。

| Abstract: | The cyclic water flooding in layered heterogeneous sandstone reservoir has been studied bymeans of VIP simulator and pseudo - 2 - layer geologic model in order that the cyclic water flooding methodwould be tested and widely used in field in this paper. By studying the influence of various geologic factors anddevelopment schedule on cyclic water flooding results in layered heterogeneous sandstone reservoir. The workmechanisrn of cyclic water flooding in layered heterogeneous sandstone reservoir has been gained. |
