METHOD FOR GAS CONDENSATE SURVEYS OF WELLS AT CONSTANT TEMPERATURE OF SURVEYED GAS IN A SEPARATOR Russian patent published in 2023 - IPC G01N25/46 

FIELD: gas wells.

SUBSTANCE: gas condensate survey of wells in fields with abnormally low reservoir temperatures. According to the claimed solution, at a constant gas temperature or its specified temperature limits in the gas separator, a stable and complete separation of the initial gas mixture is achieved with a more stable phase ratio (gas - condensate). To do this, the initial gas flow is heated at the inlet to the separator by means of a heat exchanger. As a heat carrier, water vapor from “ППУ-3М” mobile units is used, which is supplied to the annulus of the heat exchanger. The gas is heated to maintain its preset temperature during well operation in the control test mode to measure all process parameters and take samples of the separated gas and saturated condensate.

EFFECT: increasing the reliability of the final results of the survey.
