Poor efficiency of displacement coverage while applying the methods of physical-chemical and gas treatment of the deposit is predominantly associated with the issues of viscous fingering and interphase properties of displaced and displacing fluids. An effort is made in this work to study a perspective method of treatment of the deposit allowing providing intra-reservoir reaction of carbon-dioxide emission. The paper presents the results of experimental studies dedicated to the search of new methods of treatment of oil deposit with gas-fluid banks. A possibility of creating banks of gas-fluid systems in the process of reaction of alkaline agents with hydrocarbons containing active acid components is shown as well. A field method based on the effect of leveling of displacement front and increasing the coverage of poor-drainage areas of the layer due to the formation of gas-fluid systems in the reservoir conditions is offered.
