Numerical Simulation Of Steam Flooding In The Back Pattern Of Jin 91 Block

In water flooding oilfield,due to differences in pore structure and wettabilit y ground conditions,injection water seepage exhibit different characteristics.Duri ng the oil field development,there are still more than half of the oil left in the reservoir pores become surplus oil.Form water flooding out of the law and the remaining oil seepage and formation mechanism,to gain insight into the formati on of the law and the distribution of the remaining oil field development and pr ovide a scientific basis for the development of oil fields.In this paper,a series of composite flooding is introduced,and a series of effects are achieved through system adjustment and monitoring.Meanwhile,with the tertiary oil recovery tec hnology is widely used in the oil field,the role of the different forms of EOR methods used for the remaining oil is not the same.
