Abstract
Air foam flooding is an important means in tertiary oil recovery. As of July 2013, in the case of low recovery degree, Da Gang oilfield has entered high water cut period, thus increasing of recovery is under pressure. This experiment simulated the actual reservoir temperature and pressure, through the establishment of physical model, implemented a series of contrast tests, systematically evaluated four variable parameters, including gas liquid ratio, injection mode, permeability, and injection speed. Experimental results has cleared the effect of variable parameters on air foam flooding, so as to provide guidance for oilfield production.Keywords
