For the main polymer flooding oilfield expansion and infill wells three times the area of deployment, the proposed development mode II oil reservoir of polymer flooding and thin and poor combination of three encryption. In this paper, the use of leading edge water monitoring methods and principles of the plane heterogeneity through physical simulation to study the effects of different mining methods II oil and a combination of the three encryption effects of flooding. Studies have shown that, together with the water flooding recovery can be increased by nearly 19 percent, higher than the water poly alternate drive about 4%, the injection pressure is about three types of reservoir 0.3MPa, flat stage water flood sweep efficiency compared with an average of 30.95%. Meanwhile polymer injection can increase oil recovery by 21%, but the limited ability of three types of oil injection, polymer injection pressure during injection 0.22PV up to 0.8MPa, water flooding stage by an average of 30 percent compared to the plane sweep efficiency. The water flooding recovery poly alternately raise only 15%, an average increase of 26.95 percent driven phase plane sweep efficiency than water. Theoretical results of this study may provide a reliable basis for the future development of efficient thin and poor reservoirs.
