Study on the influence of different key parameters on EOR in LB block

The high temperature reservoir is in the water cut stage after long-term development, and inefficiency or invalid circulation caused by injected aggravated. With a long development history, well pattern has been adjusted many times, remaining oil distribution highly dispersed. Based on high-temperature conditions of target block, influence analysis different key parameters EOR effect LB- block was carried out. gas flooding chemical potential were evaluated numerical simulation method, systems defined. binary models established according to pattern, fluid physical parameters. predicted under formation dip, permeability, viscosity, saturation, effective thickness temperature. results show that factors are dip.
