针对丘陵油田构造及断裂系统复杂、储层非均质性严重、水淹程度高、现有井网对单砂体适应性较差、剩余油分布认识准确性不高等急需解决的问题,开展了单砂层精细对比和内部构型刻画研究,建立了单砂层精细成因地层格架,落实了砂层内部单砂体的连通关系和侧向变化,为后续地质建模及数值模拟工作提供了新的地质基础。研究成果既解决了一些开发生产的矛盾问题,又为二次开发试验井的部署和矿场实施提供了重要的技术支持,取得了良好的应用效果。
In view of the urgent problems to be solved in the hilly oilfield, such as complex structure and fracture system, serious reservoir heterogeneity, high water flooding, poor adaptability of the existing well pattern to single sand body, and low accuracy of remaining oil distribution, The single sand layer fine contrast and the internal structure characterization research, established a single sand layer fine genetic stratigraphic framework, the implementation of the sand within the single sand body connectivity and lateral changes for the follow-up geological modeling and numerical simulation work provided New geological basis. The research results not only solved some contradictions in the development and production, but also provided important technical support for the deployment of the second exploratory well and the implementation of the mine and achieved good application results.
