FIELD: measurement equipment.SUBSTANCE: method to determine molecular masses and densities of hydrocarbon fractions of bed fluids includes detection of fraction composition and detection of molecular masses and densities of fractions. Besides, to detect molecular masses and densities of hydrocarbon fractions of bed systems without distilling of the fluid, the fraction composition of the fluid is determined by simulated distillation, and the molecular mass and/or density of each fraction is determined by calculations on the basis of previously known results of determination of properties of fractions extracted in process of distilling of true boiling point of fluids, which have similar physical and/or geological properties.EFFECT: development of the method to determine molecular masses or densities of hydrocarbon fractions of bed systems without fluid distilling.1 dwg |
