This article provides an analysis of the characteristics of the movement of gas inflow in a porous medium. The theoretical part of the article allows one to imagine what parameters and factors affect the operation of gas wells. Also, the calculation of the rate of gas inflow to the wells, the calculation of the dynamics of gas production and reservoir pressure in the constant drawdown mode was carried out. Thus, according to the results of hydrodynamic studies, we learn that during gas sampling time, the flow rate decreases, that is, the amount of gas extracted from the reservoir for a certain period of time is equal to the change in gas reserves in the reservoir, since the reservoir is closed, then the reserves are limited and not replenished from outside and that with a change in the value of the radius of the well, the pressure at a given point in the formation changes over time, that is, the pressure will decrease.
