FIELD: oil and gas industry. ^ SUBSTANCE: method for determination of gas flow rate and gas factor of product of wells operating under intake pressure below saturation pressure includes measurement of annular pressure and dynamic level of fluid in annular space, oil density under standard conditions, temperature and gas solubility factor with correcting factor, determination of gas factor of oil supplied from tubing string. After that well flow rate is measured as per fluid, also water content, change of annular pressure and dynamic level upon closed annular valve and time of measurement are measured. In addition gain of gas factor and gas flow rate is determined as per annular space. ^ EFFECT: improving accuracy of gas factor determination. |
