| description | The invention discloses a method and equipment for exploiting a gas-condensate well, and belongs to the technical field of oil-gas field gas exploitation. The method comprises the following steps: a high-pressure gas is throttled and depressurized through an underground throttle device to obtain a first gas with a pressure which is less than a first preset pressure; the first gas absorbs heat of stratum during a process of arriving at a well-mouth gas nozzle from the underground throttle device to obtain a second gas; and the second gas is throttled and depressurized through the well-mouth gas nozzle to obtain a third gas with a pressure which is less than a second preset pressure, and the third gas absorbs the heat of stratum while passing through a surface pipeline to obtain a fourth gas, thus throttled and depressurized exploitation for the gas-condensate well is completed. According to the invention, the problem of blockage of single-stage throttled hydrates is avoided through carrying out first-stage thr |
