In a computational experiment, the analysis of the influence of taking into account the dependence of the equilibrium conditions of hydrate formation on the reservoir waters mineralization type on the formation of hydrates in wells during natural gas production was carried out. The study was carried out within the framework of the model of joint operation of the system "reservoir – well" during its thermal interaction with surrounding rocks. The dynamics of changes in temperature, pressure, moisture content of gas and flow section in wells are predicted. It was found that when taking into account the mineralization of reservoir waters, the time interval from the moment of starting wells to the their complete blockage with hydrates increases.
