Geochemical Characteristics and Genesis of Crude Oils of Carboniferous and Triassic in Tahe Oil field of Tarim Basin

Abstract

Abstract:

Because Tahe oil field is the largest marine carbonate rock oil field of the Tarim Basin, its genesis is of great interest.
By means of to the high-resolution GC-MS analysis of the oil samples from Carboniferous and Triassic Tahe oil field, this paper
studies biomarkers and discuss their genesis. The Pr/Ph, Pr/nC17 and Ph/nC18 data indicated that oil formed from sapropel
organic matters of reducing environment. Abundance of gammacerane C30⁺ hopane indicates that the oils formed from saltwater
environment. The abundance of C27 sterane, tricyclic terpane, tetracyclic terpane, and higher tricyclic terpane vs hopane
parameters show that original source materials are homonemeaes. Rearranged sterane/sterane, Ts/(Ts+Tm), and C29ββ/(ββ+αα)
are 0.24~0.40，0.28~0.50 and 0.56~0.63，respectively. All of these show that the maturity of the oil is high. The occurrence of
25-norhopane indicates that the oil experienced some degree of biodegradation. Comparison of oil and source rock suggests that
the oils of the main source rock came from the middle-upper Ordovician source rocks.

Key words: Tarim basin, Tahe oilfield, Carboniferous, Triassic, oil geochemistry
