FIELD: oil and gas industry.
SUBSTANCE: measurement method of oil and associated gas flow rates in oil wells involves supply of extracted products from tubing string to separator. Products are separated in the separator into gas and oil. Oil and gas are extracted subsequently from separator and they are measured by means of a float and flow switch as to the time of filling and emptying of the separator measuring part respectively. At that, during measurement periods there performed is extraction of gas separated at the bottom-hole pump inlet from annular space of the well and it is supplied directly to gas cavity of separator.
EFFECT: improving measurement accuracy of oil and associated gas flow rates.
