胜坨油田特高含水期剩余油分布仿真模型

胜坨油田已注水开发36年，处于综合含水率达95％的特高含水期，剩余油分布零散，提高采收率难度较大，根据对大量含油砂岩薄片的观察，提出特高含水期微观剩余油分布的5种模式，采用三维数据可视化技术，分形几何理论以及计算机图形及图像处理最新技术，建立了剩余油人布仿真模，揭示剩余油形成机理和分布规律。彩图11表1参31（孙焕泉摘）。

The simulation models of remaining oil distribution at super-high water-cut stage of Shengtuo oil field

Shengtuo oil field has been developed under water flooding for 36 years. Now it is at super-high water-cut stage with 95% of composite water cut and its remaining oil is scatteredly distributed. It is difficult to improve oil recovery. Based on the examination results of a large amount of oil-bearing sandstone thin sections, the authors advance 5 kinds of model of the micro distribution of remaining oil at super-high water cut stage. By using the visualization technology of 3D data field, fractal theory and new computer graphical and image processing techniques, the simulation models of the distribution of remaining oil, which can be used to bring to light the formation mechanism and distribution pattern of remaining oil, were built up.
