| Abstract: | In order to improve the effect of low permeability oilfield water flooding development,and carry out the study of polymer enhanced foam profile to improve oil recovery.According to the field geological and reservoir conditions,the establishment of typical geological conceptual model of geological model can more fully reflect the formation conditions and well pattern static conditions.On polymer enhanced foam profile control injection-production parameters were optimized.The research results show that polymer enhanced foam profile control best injection-production parameters as follows:the polymer molecular weight is 8 million,polymer concentration of 1000 mg/L,the best concentration of foaming agent is 0.25%(mass fraction),gas liquid ratio is 1:1. |
