Abstract

The composition of Bazhenov and Abalak Formation rocks of Western Siberia is presented. Correlations of macro- and micro-components concentration with the base mineral and organic matter content in rocks are showed. Investigations of trace elements allow determining sedimentation conditions: redox conditions, hydrogen sulfide contamination and the source of the sedimentary material. The results showed that the rocks of the Bazhenov Formation were formed at low flows of clastic material under reducing conditions and a periodic hydrogen sulphide mode.

Summary

Introduction

The composition of Bazhenov and Abalak Formation rocks of Western Siberia is presented. Показаны корреляции концентрации макро- и микрокомпонентов пород с содержанием основных минеральных компонентов породы и органического вещества. Наибольшие перспективы имеют породы баженовской свиты, которые характеризуются высоким содержанием органического вещества. Распределение микроэлементов в породах контролируется минеральным составом породы, но для пород с высоким содержанием ОВ кероген также нужно рассматривать как фазу.
