DEFINITION METHOD OF CONTENT OF FOLLOWING OIL IN PRODUCTION OF GAS-CONDENSATE WELL Russian patent published in 2010 - IPC G01N21/35 E21B47/00 

FIELD: oil-and-gas production.

SUBSTANCE: definition method of following oil in production of gas-condensate well includes definition of oil density by infrared spectrometre. It is constructed gauge dependence of transmission density on concentration of oil in dissolver in the form of "pure gas condensate" or alkan, used in the capacity of blank sample during calibration and following measurements of concentration of oil in surveying sample by value of value of optical density. Before measurement of optical density of blank and surveying sample it is implemented scanning of samples spectrum in the range 2700-3000 nm and fixation of maximal value of intensity of light signal in mentioned range of spectrum for each sample. Measurement of optical density of surveyed sample is implemented at the wave length corresponding to the fixed maximal value of signal considering measured value of optical density of blank sample measured at the wave length corresponding to fixed maximal value of blank sample signal.

EFFECT: invention provides increasing of measurement accuracy and increasing of the range of measured concentrations and also provides reduction of time consumption for samples preparation.
