## MATHEMATICAL MODELING OF DISPLACEMENT OF OIL BY WATER UNDER A CYCLIC ACTION ON THE CRACKED-POROUS STRATUM

V. M. Konyukhov, A. V. Kosterin, and A. N. Chekalin UDC 532.546 A mathematical model is proposed for studying unsteady processes of displacement of oil by water and evaluating the efficiency of a cyclic action on the stratum. A numerical model is presented. An analysis of calculation results is given. An optimum value of the period of the action is obtained that is in agreement with oil-field experimental data.
