摘　　要：设计了一套研究指进、剩余油分布的实验装置，进行了不同粘度比，不同驱替速度下的水驱油实验，可实现流动图像实时采集，系统地提出了驱替速度的限制条件及泵排量等实验参数的确定方法．A set of experimental device to study fingering and remaining oil distribution is designed for experiment of water displacing oil under various viscosities and displacing rates. Flow image acquiring can be achieved through the device. This paper offers a systematic method for determination of displacing rate, pumping rate and other experimental factors. The potential recovery in areas around inlets and outlets is first emphasized. An observed critical phenomena about influence of flooding rate on recovery is first reported.
