FIELD: measuring equipment engineering, possible use at wells and zones for rough processing of gas. ^ SUBSTANCE: method includes filling measuring resonator with flow of gas-liquid mixture and measuring its resonance frequency, separating gaseous phase flow from liquid phase flow, filling supporting resonator with it, measuring resonance frequency and quality of measuring and supporting resonators and computing volumetric shares of liquid hydrocarbon condensate and water. For excitation of resonators, radio waves of decametric spectrum are used. Device consists of frequency control block, connected to generator of swaying frequency, output of which is connected to input of power divider, while first output of power divider is connected to block for measuring and processing frequency, and second one - to input of measuring resonator, mounted in narrowed cut of tubular section, built into pipeline by means of flanges. Output of measuring resonator is connected to first detector section, connected to block for measuring and processing frequency. Block for filtering gaseous phase of flow and tubular section with supporting resonator are by means of flanges built into draining section of pipeline, connected to adjustable valve, mounted at outlet of tubular section with measuring resonator. Third output of power divider is connected to input of supporting resonator, output of which is connected to second detector section, connected to block for measuring and processing frequency. Resonators are filled with dielectric with high dielectric penetrability and low losses at working frequency of mode TM010. ^ EFFECT: invention makes it possible to determine volumetric shares of liquid hydrocarbon condensate and water in flow of gas-liquid mixture of natural gas. ^ 2 cl, 2 dwg |
