| description | The article describes the results of studies of crude oils microelements composition in Chekan, Tumutuk and Tumutuk-Chekan satellite deposits of Romashkinskoye oil field. It was found that mentioned deposits belong to the group enriched in microelements. Median content of trace element in different producing horizons differ markedly. Investigated crude oils are characterized by very high V/Cu and V/Pb, which may indicate a slight manifestation of catagenetic changes. However such conclusion contraries to the rather low values of V/Fe which imply a significant elaborateness of naphthides. Median values of Ni/Cu (from 146 to ~330) suggest the absence of significant migration of naphthides as well as a sufficiently low level of their catagenetic transformations. It was established that on the diagram GdN/YbN-Eu/Eu* majority of data points of crude oil are localized in the field typical of fine-grained clastic formations, in which a significant or dominant role belongs to the products of erosion of primitive Archean substrates. The median value of Pt/Pd in the whole oils of Romashkinskoye field is ~60. Crude oils of Chekan, Tumutuk and Tumutuk-Chekan deposits according to the ratio of platinum group elements belong to the ruthenium-rhodium type. |
