Method for evaluating adaptability of polymer gel profile control agent to oil reservoir

The invention provides a method for evaluating adaptability of a polymer gel profile control agent to an oil reservoir. The method comprises the following steps: step A, preparing cement artificial rock cores; step B, preparing an aqueous stratum solution; step C, preparing the polymer gel profile control agent; step D, carrying out displacement on one cement artificial rock core by respectively using the aqueous stratum solution and the currently prepared polymer gel profile control agent and calculating the residual resistance factor of the cement artificial rock core; step E, carrying out displacement on another cement artificial rock core by respectively using the aqueous stratum solution and a pure polymer liquid and calculating the residual resistance factor of the cement artificial rock core; and step F, determining a minimum gel forming concentration of a to-be-measured oil reservoir stratum according to a ratio of the residual resistance factor calculated in the step D to the residual resistance factor calculated in the step E. With the method, the polymer gel profile control agent with an appropriate concentration can be selected and used for plugging of the oil reservoir stratum, and cost is low and waste of resources is small in the process of construction.
