摘要
油藏进入高含水开发期以后,主力油层基本上水淹,由于构造、储层非均质性和井况影响形成的剩余油分布零散。针对高含水期多油层油藏的特点,在细分流动单元的基础上,对微构造、储层沉积微相、储层物性和非均质性进行了研究,并建立油藏三维可视化地质模型;在油藏精细描述的基础上,对剩余油分布进行定性分析和定量研究,然后根据剩余油分布特点采取不同的挖潜措施。研究成果应用于矿场生产后取得了良好的效果。
Major reservoirs were flooded during the high water-cut development periods. Influenced by structures, heterogeneity and well conditions of reservoirs, remaining oil distribution was scattered. In allusion to the characteristics of multi-layer reservoirs at high water-cut stage, based on fine flow unit division, microscopic structures, reservoir sedimentary microfacies, reservoir physical properties and its heterogeneity were studied and a 3D visualization geologic model was established. On the basis of fine reservoir description, qualitative and quantitative study was conducted on remaining oil distribution, different measures for tapping the potential were taken according to remaining oil distribution. The result is used in field production and good effect is achieved.
