PHYSICAL SIMULATION SITUATION OF MICROBE OIL RECOVERY TECHNOLOGY

In view of Research situation on physical simulation of microbe oil recovery technology,analyzed its growth,metabolize,migrate and block in porous media,introduced emulsify-carry,strip of Oil film,biogas and its concentrate on local interface.The growth of microbe in porous media is the result of competition and cooperation,and the cooperation is showed on utilization of nourishment,migrate or block of microbe in porous media is based on whether there is relative immovable habitat,and it is not easy to block in flowing fluid.The microbe of internal or exterior can all enhance oil displacement effectiveness 6 to 15.The future research on microbe oil recovery technology should be concentrate on following aspect: quantification of oil displacement mechanism,recognize and selectivity active on useful microbe,improve the simulation method and its similarity with field experiment.
