VARIATIONS OF THE HYDROCARBON COMPOSITION OF OIL-FIELDS IN KHANTY-MANSI AUTONOMOUS OKRUG - UGRA
The article presents the results of studies of the hydrocarbon composition and geochemical parameters of the oil-fields in KhMAO - Ugra. It was found that the variations of the hydrocarbon composition of the studied samples are large-scale, but most of the characteristics of the composition are described by a Gaussian distribution. In accordance with the existing geochemical classification of the hydrocarbon composition of oil, extracted from different wells of the field samples can be assigned to objects of different genetic type of the original organic material and formation conditions.
