SUMMARY
An innovative technology of complex hydrogen and thermobaric chemical effects (CHTBCE) on the productive formation of oil (gas) wells has been developed with the aim of stimulating hydrocarbon recovery. The basis of this technology is the integrated use of the anomalous properties of hydrogen under the conditions of a multistage thermal-gas-chemical chemical-technological process (CTP). Improving the effectiveness of the technology requires a significant improvement in the controllability of the underlying CTP.An experimental complex has been created for studying the kinetics of thermobaric chemical processes and physical modeling of the complex effect, including hydrogen, on the change in the filtration-capacitive characteristics and rock permeability. The complex allows to reproduce the technological features of the implementation of the chemical-technological process, provides its course in conditions as close as possible to real reservoir.It has been experimentally proved that by adding activators and inhibitors of chemical reactions to the base process fluids, it is possible to obtain different types of processes and their individual stages in the nature of the flow. It is shown how the use of hydroreactive agents based on aluminum makes it possible to obtain hydrogen and increase the permeability of rocks at the low-temperature stage of the process. The introduction of polymeric nitrile paracyanogen also activates and retains the high-temperature stage of the process at which hydrocracking of heavy hydrocarbons occurs.A methodology for determining the most effective chemical-technological process of CHTBCE technology is proposed and developed. The method is based on a comparative analysis of the results of the effects of different types of CTP on the restoration of the permeability of formation damage rock core samples.The research methodology created allows to experimentally determine the most effective CTP of the CHTBCE technology for use in wells with various reasons for the decrease in productivity
