In order to improve the enhanced oil recovery in the xingshugang oilfield, looking for tapping the potential of remaining oil, we conduct the indoor physical simulation experiment about the polymer flooding. The oil field provide the four kinds of polymer solution, that the relative molecular mass is 700×104, 2500×104, the divide from the middle, and by polymer surfactant II with. We conduct the experiment about the factors of the polymer relative molecular mass, mass concentration, polymer dosage, polymer injection time how to effect the oil displacement. The results show that, for the same mass concentration of the polymer, the more polymer relative molecular mass ,the greater the recovery degree, the bigger the injection pressure; for the same molecular weight polymer, the more mass concentration, the greater polymer flooding recovery degree ,the bigger the injection pressure; the time earlier water drive converted polymer, the greater polymer flooding recovery degree. If the conditions of the oil field is allowed, we can advance polymer flooding. So the production time will be shorten. We combined with the actual production conditions, and considered the economic factors, for the xingnan development area, it is thought that the Portuguese I1-2 layer is used by the polymer flooding. And that it should be preferred the polymer relative molecular mass which is 700×104 and Polymer surfactant Ⅱ. Further the polymer dosage is about 0.6PV. It provide the theoretical basis for enhancing oil recovery about the xingshugang oilfield.
