| 摘 要： | 东濮凹陷文东油田沙三中亚段低渗透储集层非均质性强，层间干扰严重，纵向水驱动用程度不均匀，严重影响开发效果。研究储集层的成岩相、孔隙结构特征和黏土矿物特征，分析储集层宏观、微观非均质性对剩余油分布的控制作用，结论是剩余油主要分布在非主力层、断层附近及井网未控制的部位。图2表1参5 |

| Abstract: | The middle part of the Member 3 in the Shahejie Formation in the Wendong Oilfield is a low permeability reservoir with a high inter-bed heterogeneity, strong inter-bed interference, and asymmetrical vertical water-flow. Such properties unfavorably affect production. The current study concentrates on reservoir characters such as lithofacies, depositional environment, pore structure and clay minerals to better understand the impact of reservoir heterogeneity on distribution of remaining oil. The remaining oil is mostly in minor reservoirs and traps associated with faults, or isolated spots. |
| Keywords: | remaining oil low permeability reservoir Wendong Oilfield |
