摘　　要：本文针对该油藏特点 ,以流动单元为基本研究单元 ,根据油藏精细描述技术研究成果 ,采用三维可视化地质建模技术建立油藏构造、砂体及储层物性三维模型 ;应用三维密网格大规模三维可视化油藏精细数值模拟技术 ,结合生产动态监测资料综合研究油藏的各种物理性质和流体在其中的流动规律 ,定量评价剩余油分布。充分发挥并拓宽了地质建模、油藏数模在油藏描述和剩余油挖潜中的作用。根据研究结果 ,采取钻调整井、油水井大修、调剖堵水等挖潜措施 ,充分挖掘剩余油潜力。油藏开发调整效果显著 。In accordance with the characteristic of S2L reservoir in Wen51 block, this paper regarded the fluid flow unit as basic study unit and applied 3D visual geological model to set up reservoir structure model、sandstone model and reservoir 3D physical parameter model with reservoir detail description results; combining with production performance data, the paper applied dense grid and large-scale reservoir detail simulation technology to research and quantitative evaluate the distribution of remaining oil synthetically. In accordance with research results ,it adopted the main tapping production potential methods, such as drilling adjustment well、oil well and injection well servicing operation、profile control for water shutoff and so on,to tap the remaining oil adequately,combining with matching production-injection technics technology. The result of reservoir development and adjustment is remarkable, production rate was increased, decline rate was slower, water drive recovery efficiency was enhanced.
