METHOD FOR OBTAINING REPORTING DATA ON GAS-CONDENSATE CHARACTERISTICS OF PLASTIC GAS FOR STABLES UNDER ABNORMALLY HIGH PLATE PRESSURE Russian patent published in 2019 - IPC E21B43/00 E21B47/00 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the oil and gas industry, in particular, to methods for checking the quality of field information on gas condensate characterization, in particular, to methods for controlling the composition and properties of the reservoir gas. In the course of geological exploration and in the process of monitoring the development of an oil and gas condensate field, gas condensate studies are carried out, including the field part – measurement of the operating parameters of the well, gas-condensate production rates, gas separation, unstable condensate, produce samples of well production, as well as a set of laboratory studies – determining the composition and physical and chemical properties of the gas reservoir, perform thermodynamic studies on the installations of phase equilibrium. After that, the results of gas condensate studies are analyzed, screening and adjustment of the obtained initial data on gas condensate characteristics is performed. Based on the analysis performed, a mathematical model of the gas reservoir is created, which is adapted to the actual data on the phase behavior of the gas reservoir and is used in the compositional numerical filtration model of the field.

EFFECT: accuracy of determination of the gas-condensate characteristics of the reservoir gas is improved.
