METHOD FOR DETERMINATION OF DISPERSION DEGREE FOR WATER AND GAS MIXTURE Russian patent published in 2014 - IPC E21B43/22 G01N13/02 G01N15/02 

FIELD: oil and gas industry.

SUBSTANCE: method includes receipt of water and gas mixture under high pressure, sampling of water and gas mixture and its transfer to a metering tank at the same pressure. Before measurement volume of the metering tank is measured and in measurement process change in free gas pressure, volume of free gas and the respective increment in free gas volume is recorded permanently, total volume of gas is determined for the taken sample; then dependency of free gas volume in the tank ΔP id determined and re-calculated to dependency of pressure change (ΔP) on relative share of the current free gas mass mig/mg, where mg is the total quantity of gas mg in the taken sample, mig is a current value of the free gas mass; then radius is determined for gas bubbles contained in the share of the current free gas mass according to the following formula: $$r_i=\frac{2\sigma }{\Delta P_i}\text{, }$$ where σ is interfacial tension and function of bubbles radius distribution determined.

EFFECT: provision of disperse degree measurement for water and gas mixture both in transparent and non-transparent dispersion medium.
