A Computer Simulation Study of High Concentration Polymer Flooding

Abstract

Considering the high cost and long term of field experiment with high concentration polymer flooding and the irreversibility of reservoir development process, in order to ensure the best development results of the production block, a numerical simulation study was carried out in this paper to calculate the high concentration polymer flooding development programs of Xing-5 polymer drive pilot area in Daqing oil field of China. Through comparing the development indexes, the optimal program was selected. Simulation results show that the more amount of polymer is injected and the higher the injection concentration is, the better development results can be obtained. The optimum injection mode is continuous injection of high concentration polymer, and the pilot area should bring high concentration polymer flooding into operation as early as possible. So this work provides theoretical directions for the work of future development management of this test area.
