Abstract

Abstract:

Pore free hydrocarbons and inclusion hydrocarbons in 6 Silurian bituminous sandstone samples from the Tazhong area of Tarim basin are separated and analyzed with GC and GC-MS.The analysis results show that pore free hydrocarbons and inclusion hydrocarbons have different characteristics.The pore free hydrocarbons are represented by light hydrocarbons of pre-peak distribution and peak carbon number at nC₁₆ or nC₂₀,without odd carbon number predominance,which are usually associatee with significant biodegradation.The inclusion hydrocarbons are represented by heavy hydrocarbons of bimodal distribution and peak carbon number at nC₂₅ or nC₂₉,with odd carbon number predominance.In respect of biomarker,the pore free hydrocarbons have a relatively high concentration of tricyclic terpanes and pregnane,with the C₂₇,C₂₈ and C₂₉ steranes of asymmetrical "V" distribution;whereas the inclusion hydrocarbons have a relatively low concentrations of tricyclic terpanes and pregnane,with the C₂₇,C₂₈ and C₂₉ steranes of oblique-ascending distribution.Oil-source correlation indicates that the hydrocarbons entrapped in the inclusions of bituminous sandstone might be sourced from the Middle-Lower Cambrian source rocks,while the pore free hydrocarbons might be generated by the Middle-Upper Ordovician source rocks.

Key words: free hydrocarbon in pores, inclusion hydrocarbon, GC-MS analysis, oil-source correlation, Silurian, Tazhong area
