Abstract In overpressure reservoirs,the permeability of reservoir rapidly decreases with the formation pressure decreasing and the permeability variation coefficient is important characteristic parameter.The paper studied stable seepage flow rule of overpressure reservoir and created the method for using systematic well testing data to compute permeability variation coefficient.
