Organic Facies and Distribution Forecast of Hydrocarbon Source Rocks in Carboniferous, Northern Xinjiang

Abstract:

Carboniferous, the sedimentary basement in northern Xinjiang, formed under the circumstances of sea-land transition, sedimentary evolution and intense tectonic movement with various sedimentary facies, causing the differences in regional distribution of hydrocarbon source rocks. According to the sedimentary facies, organic matter component and organic geochemistry of hydrocarbon source rocks, organic facies in Upper Carboniferous may be divided into 5 types, which are lake delta – shallow lake – semideep lake organic facies with mineral asphalt matrix, small sporophyte, desmocollinite and planktonic algae, lake delta – shallow lake organic facies with mineral asphalt matrix, shell debris and vitrodetrinite, shallow sea and transitional organic facies with vitrodetrinite, shallow sea – shallow sea shelf organic facies with vitrodetrinite, semideep sea organic facies with clastic-bearing and planktonic-algae-bearing small sporophyte. Based on outcrop sections, drilling data and lateral prediction of seismic facies, the principal characteristics for hydrocarbon source rocks of Upper and Lower Carboniferous in Junggar, Santanghu and Tuha Basin have been described in details, as well as the distribution forecast of hydrocarbon source rocks in Upper and Lower Carboniferous from different basins.
