Calculation Method for Preferential Flowing Channel in Pinghu Oil Field

During the development of oil reservoir with bottom water, the pore structure could be changed under the long time washing by oil and water, and the Preferential Flowing Channel will be created. As a result, the bottom water will preferentially flow through these channels, and furthermore enhance the water cut and reduce the oil recovery. In order to reduce water cut and finally enhance oil recovery, the adjustment cases for the oil field should be designed under the research of multi-phase flow. This paper presents the Calculation Method for Preferential Flowing Channel and the calculation results of the layers in Pinghu oil field. The result could provide theoretical basis for next study of Adjustment Cases
