Abstract
Annotation. With the help of modern methods of physico-chemical analysis, the physicochemical properties, origin and fractional compositionof the Akshabulak oil field were studied. Using adsorption column chromatography, the oil was purified from asphaltenes and resins contained in it. The full composition of oil was determined by chromatography-mass spectrometry and the content of compounds in it was calculated by internal normalization. The NIST-08 database was used as a library of Mass spectra. The origin of the oil was discovered, studied by the ratio of 2,6,10,14-tetramethylpentadecane to 2,6,10,14-tetramethylhexadecane on the obtained chromatogram. The proven oil was formed at the seabed off the coast by origin. The fractional composition of oil and the products obtained from it was studied by the method of simulated distillation. The heat of combustion of the products obtained and the octane number of gasoline obtained from oil were determined. The results obtained as a result of the study can be used in oil refining.
