NON-SEPARATION ANALYZER OF VOLUME FRACTIONS OF GAS, CONDENSATE AND WATER IN PRODUCTS EXTRACTED FROM GAS CONDENSATE WELLS

When developing a non-separation technique for recording the components of the production of gas condensate and oil and gas condensate wells, it is necessary to solve the problem of determining the volumetric contents of these components. A promising direction for solving this problem is the technique of probing a gasliquid flow with decimeter radio waves. By passing the flow through the microwave resonator and measuring the frequency shift of the resonator and its quality factor, it is possible to determine the volume fraction of gas, water, and condensate. The algorithm for determining the volume fractions of gas, water and hydrocarbon condensate of a gas-liquid flow using the analysis of information from a microwave resonator provides an acceptable accuracy in determining the amount of condensate only at high gas-condensate factors (~ 300–1000 cm3 / m3) and low water-gas factors (~ 30–100 cm3 / m3). With an increase in the proportion of water or a decrease in the proportion of condensate, the error in determining the gas-condensate factor becomes unacceptably large, which devalues this measurement method. The error can be reduced by introducing a bypass line into the flow meter containing a filter that separates the liquid phase and a reference resonator that registers the frequency shift due to the gas phase. The filter is probed with an 8 mm radio beam, which reacts to the content of only the water component. The data obtained from the resonator and filter significantly expand the range of recorded condensate-gas and water-gas factors.
