Annotation The article deals with the problem of calculating the bottom hole pressure in the gas well, subject to risk of self-loading by condensation water. Correct choice of the bottom hole pressure is important to determine the steady state operation mode of the well. Its calculation in the case of presence of liquid in the well production is complicated by the fact that the pressure gradient calculation formulas for single-phase flows in this case do not apply. The paper analyzes the experimental data on the pressure gradients in the gas-liquid flows and proposes an approximation model for analytical calculations of pressure gradients. Approximation model for analytical calculations of pressure gradients was used for the integration of the differential equation for the pressure distribution along the wellbore. The results of numerical solutions of technological problems of well operation in conditions of water seepage are presented.
Key words gas well, wellhead pressure, bottom hole pressure, gas-liquid flow, flow rate, natural gas, gas well tubing
