METHOD OF DETERMINATION OF DYNAMIC LEVEL IN ANNULUS OF WATER CUT GAS WELL Russian patent published in 2015 - IPC E21B47/47 G01F23/14 

FIELD: oil and gas industry.

SUBSTANCE: calculation device of the information and measuring system of the water cut gas well receives the signals from the pressure and temperature transmitters at the wellhead annulus output and at well bottomhole at input of the centrifugal pump, gas flowrate, gas and liquid densities. At that the liquid dynamic level is determined as per the iteration algorithm of successive approximation of the bottomhole pressure $$P_{\text{bottomhole}}^{calc}$$ from wellhead till its equality to the measured bottomhole pressure P_bottomhole as per hydraulic dynamic formulas.

EFFECT: method of determination of the liquid dynamic level in annulus of the water cut gas well based on the designed information and measuring system by means of measurement of the product parameters at the bottomhole and wellhead.
