METHOD FOR DETERMINING WELL OPERATING PARAMETERS TO GAS-COLLECTING SYSTEM Russian patent published in 2012 - IPC E21B47/10 

FIELD: oil and gas industry.

SUBSTANCE: method involves measurement of gas flow using flow metre and measurement of content of liquid and solid impurities in gas well product using separator. According to the invention, gas flow is disconnected from gas-collecting system and is connected to flare line, end of the line is provided with portable flow metre and separator. After that wellhead pressure is set using adjustable choke being a part of well Xmas tree, wellhead pressure is the same as upon well operation to gas-collecting system. Gas flow is measured for a certain period of time. Then gas flow is back to gas collecting system. After that quality of liquid and mechanical impurities accumulated in separator during measurement is measured and content of liquid and solid impurities in gas flow is calculated by formulas.

EFFECT: method implies no reconstruction of wellhead, it allows increasing accuracy, validity and economic efficiency of control of modes of wells operation to gas-collecting system due to direct measurement of their operating parameters and reduction of costs of purchase of expensive measuring equipment for each well, its mounting and maintenance.
