In this paper, the authors conducted a study devoted to determining the most optimal compositions for the implementation of measures to increase well productivity in the conditions of active development of the White Tiger field. The results of basic experiments in the field of selection of reagents for heat treatment of the bottomhole zone of wells, together with a comprehensive analysis of the geological conditions of the studied object, show that in order to restore and multiply the permeability of formations, it is necessary to use such compositions, the mechanism of interaction of which is based on the dissolution of asphalt-tar deposits and substances with a large molecular weight. In this regard, a number of theoretical calculations have been carried out for the «magnesium + hydrochloric acid» reaction in four variants with the gradual introduction of compositions of different chemical composition and origin. At each stage, the reaction temperature was determined using both the main and alternative methods in order to increase the representativeness of the results. Taking into account the imposed restriction on the deviation of the determined temperature from the bottom hole, the composition of the agent that can be recommended for the treatment of productive layers of the White Tiger deposit has been previously successfully determined. It is concluded that it is necessary to study the replication of its application at analog facilities in order to improve the technical and economic performance of oil and gas production departments.
