在所建立的渗流平面物理模拟实验装置上，进行了不同油水粘度比，不同驱替速度下的水驱油实验。分析了指进、剩余油形成规律及对采出程度的影响。首次提出由于指进发育造成注入端及排液端附近的剩余油开采潜力，阐述了开采速度对采出程度影响的临界特性、回流现象、不规则渗流场中指进的自相似性，出口端油流量的波动等。对相关的剩余油开采措施及在生产中提高采出程度提出了一些新的建议。 On the established seepage plane physical simulation experimental device, the water flooding experiments with different oil-water viscosity ratios and different displacement velocities were carried out. Analyzed the fingering, the formation of remaining oil and the impact on the degree of recovery. It is the first time to put forward the potential of exploiting the residual oil in the vicinity of the injection end and the drainage end. The critical characteristics of the recovery rate, the backflow phenomenon, the self-similarity of the finger in the irregular seepage field, Flow fluctuations. Some suggestions are put forward for the related residual oil recovery measures and the improvement of production in production.
