Numerical simulation of polymer flooding in water flooding reservoir

Different influencing factors in the process of polymer flooding have different degrees influence on development effect, so it is necessary to carry out dynamic prediction before implementing scheme. In this study, reservoir model C Block established and production performance fitted. The fitted used study concentration, injection time, rate multiple timing effect Block. results show that cumulative oil increases gradually with increase combined principle economic development, there an optimal concentration Block, which 0.15 wt%; With increasing time multiple, incremental (compared water flooding) trend; For timing, earlier more conducive obtaining higher increment. under scheme block 23.8494×104 m3, 1.5042×104 m3 than flooding.
