Abstract
In this paper describes s the results of testing models for calculating bottomhole pressure in the trunk of a gas and gas-condensate well, which are a single-phase model (“dry” gas) and Adamov’s analytical formula for gas flow, adjusted for the presence of liquid. Testing was carried out using field data obtained during gas dynamic testing of wells in the V, B, VU and NU fields. The boundaries of the values of the water-gas factor and condensate-gas factor were identified, at which the calculation of pressure along the gas wellbore can be carried out using a single-phase model (“dry” gas) with an acceptable deviation.

Materials and methods
In this work, the boundaries of the values of the water-gas factor and the condensate-gas factor will be determined at which the pressure calculation along the gas wellbore can be carried out using a single-phase model (“dry” gas) or Adamov’s formula with a permissible deviation based on field data.
