METHOD FOR DETERMINING VOLUMETRIC PROPORTION AND PHYSICAL PARAMETERS OF OIL IN BRINE LIQUID OF WELL Russian patent published in 1997 - IPC

FIELD: oil production and processing industry, chemical industry. SUBSTANCE: this relates to method for control of content of oil in brine liquid of well during its operation and can be used in analyzing unmixable liquids, especially in analyzing toxic and explosion-risky liquids. According to method, sample of brine liquid is taken from trunk pipeline to measuring vessel, and sampled liquid is drawn through nozzle. Simultaneously measured are pressure differential at nozzle, liquid flow rate. Obtained is information signal on liquid flow rate in real time scale in the form of pulses, summed up are pulses obtained at different pressure differentials with recording in various memory cells of computer in accordance with signal of differential pressure gauge installed in nozzle. Then determined are volumetric proportion of oil, kinematic viscosity of oil and water, using mathematical expressions. EFFECT: high efficiency.
