| 摘 要： | 侧积夹层是河流相曲流河点坝内部重要的渗流屏障,精细刻画隔夹层的分布可以更有效地指导开发调整工作。以渤海海域典型河流相曹妃甸11-1油田为例,以沉积模式和曲流河沉积理论为指导,在井震结合基础上根据生产动态等资料,分析了主力边水油藏Lm943砂体侧积夹层的分布模式、分布范围及对剩余油的控制情况,并阐述了地下流体运动规律,为进一步剩余油挖潜工作奠定了良好的基础。

Application of lateral accretion interlayer study in fluvial edge water reservoirs of Bohai Oilfield |
| |
| Abstract: | Lateral accretion interlayer is an important seepage barrier of meandering river fluvial point bar inside and the meticulous depiction of the lateral accretion interlayer distribution can more effectively in guiding the development adjustments.By taking typical fluvial Caofeidian 11-1 oilfield of Bohai oilfield as an example,guided by deposition patterns and meandering river deposition theory,based on combined well-seismic data and production performance,the distribution patterns and distribution range of the lateral accretion interlayer from the edge water reservoir Lm943,and their control effect on remaining oil have been analyzed.Besides,the movement regularity of underground fluids has been explained and it lays a good foundation for further remaining oil tapping work. |
