STUDYING THE FEATURES OF OIL DISPLACEMENT BY ALKALINE WASTE SOLUTION IN A POLYMER COMPOSITION

In recent years, a number of new combined methods for enhancing oil recovery have been developed, which, when applied through the implementation of several oil recovery mechanisms in the reservoir, make it possible to influence both the reservoir coverage and the oil recovery factor from the reservoir, and thereby achieve a more complete oil recovery than with conventional flooding. These methods include those based on various polymer applications combined with the injection of various chemical reagents that increase oil recovery. Moreover, key requirements when selecting chemical reagents should be their low cost, sufficiency, and relatively simple application technology. Typically, to conserve energy and resources, such combined physical and chemical methods are applied in the field as slugs.
