Abstract: The foam effect on improving the core sweep efficiency and reducing permeability are investigatedby foam flooding in porous media experiments. The influence of α-olefin sulfonate (AOS ) , hydrolyzed polyacry-lamide (HPAM)concentration, gasliquidratio, corepermeability, andinjectionmethodsonfoamfloodingpropertyare explored. The experiment results show that foam flooding resistance coefficient and residual resistance coeffi-cient increase with the increasing concentration of AOS and HPAM. The foam flooding resistance coefficient andresidual resistance coefficient in the non-oil rock heart are more than three times of those in the oil-bearing rock.Under the condition that AOS and HPAM concentration are greater than a certain value, foam flooding resistancecoefficient and residual resistance coefficient are stabilized. Appropriate increasing ratio of gas-liquid can improvefoamfloodingcontrolability, buttoomuchratioofgas-liquidwillcausegaschanneling. Thesamefoamsystemdoesnot improve flooding control ability of all different permeability cores. Advanced foam injection leads to the bestmobility control than other ways. The mobility control of the alternating injection of liquid and gas foam decreasewith the increase of alternating slug.
Key words: foam flooding, resistance coefficient, gas liquid ratio, injection method
