The hydrocarbon composition of Guneshly, Neft Dashlary, Chirag offshore fields oils in Azerbaijan
F.I. SamedovaThe article presents the results of research of hydrocarbon composition of oils from prospective offshore fields Guneshly, Neft Dashlary, Chirag via gas-liquid chromatography. It is shown that in the investigated native oils the fraction C12-C18predominate and C36fractions is above 1/5 of all hydrocarbons. A comparison of hydrocarbon mixtures of C3C13from native oils, which are close to the boiling point intervals, limits the selection of gasoline distillate (IBP 200C). In comparison by identified alcane hydrocarbons, mixture of C3C13from Guneshli oil, followed by Chirag and Neft Dashlary oil differs. Among paraffins the branched hydrocarbons in Neft Dashlary oil, the normal structure of alkanes in oils and Chirag, Guneshly predominate. The highest concentration of naphthenic hydrocarbons found in the oil mixture of C3C13Neft Dashlary oil, for which the ratio of paraffinic hydrocarbons to naphthenic is -1.6.
