摘　　要：根据胜利油田单二块试验区的地质特征及处于高轮次、特高含水、低采出程度和低采油速度的开发阶段 ,立足剩余油分布规律研究 ,通过对优选出的 3口井实施调整注汽剖面 ,控制产液剖面 ,挖掘垂向剩余油潜力 。Based on the geologic characteristics in the pilot area of Block Shaner, the distributional rule of remaining oil is studied in combination with the production conditions of high production cycle, extra-high water-cut stage, low recovery percent and low production rate at the production stage. Steam injection profile is regulated, liquid withdrawal profile is controlled; tapping the vertical potential of remaining oil is performed on 3 selected wells, by which prolonged result is achieved.
