Abstract
The distribution and composition of low-molecular nitrogen-containing components in petroleum from the Lower and Middle Jurassic complex of West Siberia were investigated. The dependence of the quantitative content and qualitative composition of hetero-organic compounds of nitrogen on the geological-geochemical bedding conditions was revealed. It was established that the group and individual composition of nitrogen-containing compounds of the Lower and Middle Jurassic petroleum is typical also for petroleum from the Cretaceous and Upper Jurassic deposits of the West Siberian oil-and-gas province. No evident differences in the distribution of predominant types of low-molecular nitrogen-containing compounds were revealed in the investigated kinds of petroleum.
