Abstract
In the process of gas condensate field development and operation there is a decrease in the production well bottom-hole flow pressure. When the bottom-hole pressure drops below the dew point pressure condensate accumulates in the bottom-hole zone of the well, which leads to a formation of the condensate front. As a result, the productivity of the well is reduced both by gas and condensate.With an increase in temperature the liquid condensate becomes versatile and enters the gas phase; so the accumulation of retrograde condensate can be reduced by increasing the temperature in the bottom-hole zone. Vaporization of condensate and its transfer into the gas phase can be carried out by electrothermic treatment of the bottom-hole zone. In this case it is necessary to use special equipment – a bottom hole electrical heater.
