【 摘 要 】

The paper describes a measuring method for gas/oil ratio with a mobile setup by means of sending the free gas from annular space of a well directly to the meter, bypassing the oil-gas separation tank. Such arrangement allows reducing separator loads for gaseous phase and increasing the accuracy of measurement of both oil and gas. To assess the amount of gas being separated at pump suction, experiments were conducted on a number of fields being developed by Lukoil-Komi LLC; the experiments aimed to measure the gas coming from the annular space bypassing the separator. An empirical formula has been obtained allowing calculating the gas separation coefficient at suction of calculation at bottom pump suction depending on well oil production and making it possible to predict an amount of gas taken out of the annular space of the well during the metering.
