摘要
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。
Aiming at problems such as complicated structure and fault system,serious reservoir heterogeneity,high-degree water flooding,poor adaptability of well pattern to single sand body and low accuracy of understanding of remaining oil distribution in Qiuling oilfield,fine comparison of single sand bed and study of internal structure description are conducted, fine genetic formation framework of single sand bed is established,connection relationship and lateral variation of single sand body within sand bed are determined.All these provided a new geological basis to further geostatistical modeling and numerical simulation.The results have good application effects,and not only can resolve some contradictions during the development,but also provide important technical support to determination and field operation of pilot wells in secondary development.
