ADAPTIVE METHOD FOR MEASURING FLOW RATE OF GAS CONDENSATE WELL PRODUCTS Russian patent published in 2016 - IPC E21B47/10 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil and gas industry, can be used for measuring and controlling flow rate of gas-condensate wells and helps to increase accuracy of measuring flow rate of gas-condensate wells. Method involves continuous simultaneous measurement of volumetric flow rate of gas-condensate mixture in the main measurement and additional pipelines. Calculation of component-wise flow of gas and gas condensate and measurement of volumetric flow rate of gas and gas condensate at the outlet of separator in the additional pipeline. Comparison for each time reference values of measured flow rate with values of calculated parameters and installation based on statistical criteria of equal accuracy and compatibility of compared parameters. If compatibility of these parameters in each time series is proved, average value of flow rates in the main and additional pipelines is determined, sum of average total consumption of gas and gas condensate at the separator outlet is compared with the average flow rate at its input, and if the difference between those does not fall beyond the preset controller settings stored in memory, average values of flow rates of gas and condensate in both pipelines are compared, and if the difference of those readings extends beyond the preset controller settings stored in memory, results of measurement and calculation in the main measuring pipeline are corrected with due allowance for measurements of gas and gas condensate in the additional pipeline.

EFFECT: technical result consists in improvement of accuracy of measurement values of flow parameters of gas-condensate wells due to control of measurement results and higher reliability of their correction.
