- Аннотация: This paper presents the results of analysis of the effectiveness of thermo-chemical treatment methods using water solutions of binary mixtures of ammonium nitrate on low-permeable hydrocarbon reservoirs. The reasons for a multiple long-term increase of production rate of wells in low-permeable formations after thermochemical treatment, accompanied by a significant thermal heating of the prolonged reservoir matrix treatment with exothermic reaction of working agent decomposition, are determined. This determination is based on the results of mathematical modeling of field experiments and analysis of experimental work on hydrothermal treatment and pyrolysis of kerogencontaining rocks core samples. It is shown that, opposite to the classical thermal methods of hydrocarbon layers treatment, not only the fluid viscosity decreases, but also phase transformation mechanisms of various hydrocarbon components, including those originally included in the rock matrix, are engaged. The analysis of Romashkinskoye field core samples pyrolysis data shows a change in the composition of organic matter and residual oil, the start of generation processes and their engagement due to hydro-thermolysis.
