韵律性砂岩油藏不同部位注水开发效果研究

Study on Waterflooding Effects at Different Positions in Rhythmic Sandstone Reservoir

对韵律性底水砂岩油藏，根据其注水部位的不同，应用油水两相二维剖面模型进行模拟开发研究。根据油、水在横向和纵向上的运动情况和层间窜流情况，对模拟结果进行了分析，揭示了不同沉积韵律油藏不同部位注水开采效果的一般规律。

A two - phase(oil,water)and two - dimensional section model was used to simulate waterflooding at different water- injection positions in rhythmic bottom water drive reservoir. The simulation results were analyzed according to the lateral and vertical movements and interlayer crossflow of oil and water, and the regular pattern of waterflooding at different positions were revealed.
