description The purpose of this work is to search for an area of effective use of enzyme solutions for the intensification of oil production within fields of various geological structures due to their entry into the final stage of operation, which is characterized by a multiple decrease in oil production volumes, an increase in the water content of products and an increase in the accident rate of the producing well stock. The scientific novelty of the work is based on the empirical determination of various parameters of enzyme solutions that can be successfully regulated during the implementation of injection. Based on laboratory studies of enzyme based complexes, it has been shown that in order to prevent a decrease in enzyme activity in reservoir conditions due to high mineralization and temperature, it is necessary to include chelated compounds in order to limit the influence of metal ions. The optimal concentration of enzyme solutions and surfactants for the minimum value of surface tension has been found out, the achievement of which makes it possible to significantly increase the displacement coefficient, and, consequently, the oil recovery coefficient. To form a qualitative sample of data, the initial geological and commercial material was carefully selected and ranked, which allowed to obtain a minimum error in the calculations. The results of the study of the thermal stability of the enzyme complex showed that the interfacial tension between the solution of the enzyme complex and kerosene is much less than the interfacial tension between seawater and kerosene, which is proof of the thermal stability of the enzyme complex at reservoir temperature. The obtained material can be used both for carrying out various geological and technical measures using enzyme solutions, and for implementing a competent approach to the issue of implementing the optimal chemical composition of the working agent.
