FIELD: oil and gas industry. ^ SUBSTANCE: invention refers to measuring volume of liquid and gas in gas-fluid mixture. The invention can be implemented both in oil producing industry and in branches of industries, where it is required to measure volume of liquid and gas in a two-phase flow. The essence of the invention is as follows: the method consists in successive connection of wells to measuring, separating of production of the well and collecting liquid in a measuring capacity at the open line of gas withdrawal and closed line of liquid withdrawal, in measuring temperature and pressure, in shutting off the gas withdrawal line and in building pressure up in the capacity, and in opening the liquid withdrawal and gas withdrawal lines with measurement of liquid consumption and yield determination time. According to the invention at closed liquid withdrawal line and shut-off gas withdrawal line pressure rise is measured and time of capacity operation with shut off gas withdrawal line is fixed. Also volume of gas coming from a well together with liquid is determined by difference of products of pressure rise of free from liquid volume of the capacity and final pressure by volume of liquid having come into the capacity through time of operation with shut off lines of liquid and gas withdrawal. ^ EFFECT: increased efficiency of method due to upgraded customer characteristics of devices used for well yield assessment. ^ 2 cl, 1 dwg |
