摘　　要：东濮凹陷文203断块沙三中为深湖—半深湖浊积扇沉积,储集层非均质性强,区内断层发育,油层多而薄,开发效果较差。在油藏精细描述的基础上,利用注水井吸水剖面资料、调整井资料及综合开发动态资料,结合数值模拟技术,对油藏进行剩余油定量化、可视化研究。根据研究成果,剩余油区的水淹状况可划分为水淹区分布型和弱(未)水淹区分布型。该研究对于指导类似油藏的开发具有一定的借鉴意义。S3mid formation of Block Wen203 in Dongpu Depression belongs to deep lake- hypabyssal lake turbidite fan sedimentation. The reservoirs are highly heterogeneous, numerous, thin, and with developed faults, and the development result was poor. On the basis of meticulous reservoir description, this paper studies residual oil in the reservoir in a quantitative and visualized way by using data of injection profile, adjustment well and overall development performance in conjunction with numerical simulation. The result indicates that the watered-out conditions in the residual oil zone can be classified as waterflooded area and weak (non-) waterflooded area. This study may be of certain reference significance to similar reservoir development.
