There is seldom research on describing the changing trend of water-oil displacement efficiency based on time and water drive frontal position. In previous study, our team gave the theoretical expression of water saturation in oilwater fluid flow area based on time and distance. In this work, we mainly focus on the prediction of water-oil displacement efficiency combining the permeability experiment and theoretical expression of water saturation. This new expression gives the micro water-oil displacement efficiency in different frontal position and time. The prediction results show: that the predicting accuracy is high and practicable, and we can shorten the time and cost of experiment and this prediction method is meaningful in guiding the actual oilfield development.

"My experiences in publishing a paper with Bentham Open is good. I must say that the speed of publication in The Open Petroleum Engineering Journal is very fast. It takes only two month for the pioneer reviewing process. The delay was caused by me. And what’s more, the publisher’s office is quite helpful. I guess they are dealing with thousands emails every week, but they process my request in a very short period of time."
