PRODUCTION STIMULATION BY CONTROLLING THE PROPERTIES OF CLAY MINERALS DURING OIL DISPLACEMENT BY WATER IN CLAY RESERVOIRS

A technological method of alternate application of fresh and brine waters for intensifi cation of involvement of residual oil reserves in development during oil displacement in clay reservoirs and a hydrodynamic model of predictive assessment of real mechanisms of the indicated intensifi cation are proposed. An increase in oil production with the use of the proposed method as a result of ensuring blocking of watered zones by regulating clay content of the rock and water fl ow direction to less developed (slightly-low-permeable) sections of the reservoir is established.
