Abstract: "The industrialization test on polymer flooding in Lower Karamay reservoir in District East 7-1 of Karamay oilfield" is one of the important oil development projects arranged by PetroChina in 2005. This paper presents the fine geological model and reservoir numerical simulator for this test area by analysis of the reservoir geology, and proposes the optimal oil displacement program. Meanwhile, the effect of program and the concentration of polymer output are forecasted in order to provide scientific basis for field operation. Based on the production performance of this test area, the polymer flooding tracking simulation is made for the purpose of timely adjustment of the physical and chemical parameters of the polymer, allowing them to approach the real situation and obtain the optimum effect of polymer flooding.
