Research on Injection Capacity of Polymer Flooding in Sublayers in Daqing Oilfield

Wenlong ZHANG, Bing ZHAI, Kaoping SONG, Mei WANG


According to the application of numerical simulation method, this paper firstly analyzed the single factor including the reservoir parameters, chemical agent parameters, injection parameters and well spacing. And established the single factor regression formula of polymer injection pressure, then designed the orthogonal test scheme of different parameters. The paper also calculated the injection pressure increment of different scheme by the numerical simulation method, and established the multi factor quantitative formula between pressure increment and the factors based on multiple regression analysis. Through the application of field examples, the error between the calculation result of model and the actual result is within the allowable range of project. After Verifying the reliability of injection capacity model, it could provide theoretical support for injection capacity analysis of polymer flooding and injection scheme design.
