dc.description.abstract	The most of the world's major fields in the final stages of development requires new intensive methods of improving oil recovery. In recent decades, interest in in-situ heat generation has increased dramatically due to the injection of thermochemical fluids as a complex impact on well productivity to clean the bottomhole zone of the formation and intensify oil-saturated zones with impaired porosity and permeability properties. Rational use of this method in the well requires preliminary determination of the efficiency of injection of such fluids on core models of different reservoir types under reservoir conditions of the field. In this work well known liquids such as binary mixtures and hydrogen peroxide having a high thermo-chemical potential have been tested in physical 1-D modeling by injecting these fluids through rock with temperature and pressure rise recording. Based on the obtained data during filtration experiments, it was shown that hydrogen peroxide injection through a disintegrated core model leads to partial cleaning from immobile oil and heavy deposits included in the rock, when the model is heated to 180-240 ?C because of the decomposition of hydrogen peroxide with a catalyst and under the catalytic influence of the rock. During tests using a thermos-chemical fluid including a solution of ammonium nitrate with nitrites of alkali metals, various thermobaric effects were observed when injected into a composite core model with varying reaction initiators and the addition of thermo salt-resistant surfactant. The injection of these mixtures showed the possibility of reaching high temperatures in the initial zone and further advancement of the thermal front along the model through the porous medium. Thereby the results of studies can provide a preliminary assessment of the effectiveness of thermochemical treatment in fields operated at a late stage of development for cleaning the bottomhole zone from deposits, reducing the skin factor and increasing well productivity.	ru_RU
