METHOD AND DEVICE FOR DETERMINING VOLUMETRIC CONCENTRATIONS OF GAS, WATER AND HYDROCARBON CONDENSATE IN STREAM OF PRODUCTS OF PRODUCTION OF GAS CONDENSATE WELLS Russian patent published in 2024 - IPC G01F1/74 

FIELD: measuring equipment.

SUBSTANCE: invention relates to a method for determining volume fractions of gas, water and condensate in production products of gas condensate wells. Method for determining volume fractions of gas, water and hydrocarbon condensate in a stream of production products of gas condensate wells consists in sampling a representative sample of production products and passing it through a microwave resonator, filled with filtering material, beating liquid phase, measuring volume of gas free from liquid phase, and measuring the resonance frequency of the microwave resonator and its Q-factor before passing a certain amount of the sample and after passing it and then calculating the volume fraction of water and condensate using analytical formulas. Measurements are carried out once at temperature above 0 °C, and another time—at temperature below freezing point of water condensate or water-methanol solution, wherein simultaneously with resonator measurements of the amount of water in the filter, the amount of water is also determined from the attenuation of millimeter-range waves passing through the open ends of the microwave resonator. Also disclosed is a device for determining volume fractions of gas, water and hydrocarbon condensate in the flow of products of production of gas condensate wells. Device is made with possibility to simultaneously determine amount of water by attenuation of waves of millimeter range simultaneously with resonator measurements of amount of water in microwave resonator filter, passing through the open ends of the microwave resonator, which is made as an open resonator in the form of a parallelepiped and is located on a thermoelectric battery, which enables to set the temperature of the microwave resonator filter in the range of +100... −30 °C.

EFFECT: enabling measurement of small condensate-gas factors (~50–100 cm³/m³) with an acceptable error (~5%).
