METHOD OF MEASUREMENT OF PRODUCTION OUTPUT OF WELLS Russian patent published in 2010 - IPC E21B47/10 

FIELD: oil-and-gas production.

SUBSTANCE: according to method it is drilled condensate pool system of extracting and injection points in version of horizontal and it is implemented on the basis of cycling-process. It is collected liquid in separation tank with simultaneous removal of gas from separation tank through gas counter. It is defined time of collecting in separation tank of liquid and volume of gas. It is disconnected separation tank from well. It is measured watering of liquid by stream-oriented moisture indicator. After disconnecting of separation tank from well, channel of gas removal from separation tank is closed and there are defined mass of collected from separation tank liquid M_L0, absolute temperature T₀, absolute pressure P₀ and volume V₀ of gas, which is in separation tank under phase interface. After disconnecting of each i-position of liquid there are defined mass of liquid M_Li which is in separating tank, absolute temperature T_i, absolute pressure P_i and volume V_i of gas, which is in separation tank under phase interface. Gas flow rate is calculated after pumping out of n-portions of liquid considering amount of dissolved in collected liquid gas, mass of which is defined b method of extrapolation up to values of absolute pressure 101325 Pa and absolute temperature 293,15 K of curve degasification, constructed according to proposed mathematical expression.

EFFECT: reduction of definition inaccuracy of gas flow rate ensured by accounting of amount of dissolved in liquid gas and reduction of definition inaccuracy of oil flow rate ensured by reduction of measurement errors of liquid watering.
