A New Method for Potential Evaluation of Compound Flooding of Tertiary Oil Recovery

Abstract

Abstract Compound flooding and tertiary oil recovery is one of the leading methods to improve recovery efficiency in oil and gas development in China, Because there are certain requirements on the exploitation environment and technology in the process of petroleum exploitation, it is necessary to evaluate and analyze the reservoir potential in advance. Currently, our research team has integrated this method into the tertiary oil production potential evaluation software EORSYS3.0. In this paper, a new combined flooding potential prediction model is established to improve the accuracy of reservoir potential prediction results by changing the reservoir water cut of displacement front viscosity.
