Issues of equipment and technology for operating gas wells in conditions of condensate and flooding require constant improvement. The result of our proposed technology is to increase the productivity of flooded gas wells by increasing the rate of upward gas flow from the bottomhole itself. The effect of reducing the diameter of the lifting pipes and increasing the velocity of the gas-liquid flow at the bottomhole is achieved by lowering the tubing perforated in the lower part of the string to the lower perforations of the production string. The results of field tests are given. Applicability criteria for the proposed technology are identified.

Keywords: Gas well, fluid removal technology, perforated tubing
