摘要
FIELD: oil and gas industry.;SUBSTANCE: invention is referred to an oil-and-gas industry, in particular, to engineering methods of gas-condensate fields (GCF) development with high content of a condensate in a formation gas (FG). For this purpose in the camera pVT a recombined sample of gas of initial makeup at formation conditions is made. Step modelling of GCF performance history on a exhausting mode by differential condensation (DC) discharge of gas from the camera pVT. FG and condensate volumes are defined and samples are taken for the analysis with the subsequent calculation of super-compressibility factor of FG for each stage of development and the alteration forecast of super-compressibility factor FG by means of analytical dependence. For each stage of a DC after creation of initial thermobaric formation conditions the volume of loaded FG, the FG volume, sampled from the camera pVT, and FG volume, dedicated in the form of a wet condensate. FG volume, remained in the camera pVT, at each stage is counted by the balance method. Thus super-compressibility factor of FG at each stage of DC is defined by the given mathematical dependence.;EFFECT: accuracy increase; reception of source data for plotting of prospective dependence of alteration of super-compressibility factor of FG from formation pressure in performance history of GCF.;1 dwg, 5 tbl, 1 ex
