Oil and gas sources from the Luliang Oil Field in the Junggar Basin, (Xinjiang)

摘要

摘要: 地质色层效应、输道层矿物的吸附和储集层中油气的热演化,导致了生物标志物的多解性和常规油气源研究的不确定性。四面临凹,且凹陷都有可能成为其油气源区的陆梁油田油气源研究更具挑战性和难度。笔者通过对周边凹陷的构造演化、烃源岩生烃能力和地球化学特征、输道层的演化和特征以及陆梁油田油气地球化学特征进行分析,运用三环二萜烷C₂₀、C₂₁、C₂₃和甾烷C₂₇、C₂₈、C₂₉等生物标志物进行对比,认为陆梁油田的油主要来源于具有巨大生烃潜力的盆1井西凹陷二叠系烃源岩,气主要来自侏罗系烃源岩。

Abstract: The geological chromatographic effect, absorption of mineral in conveying beds and thermal evolution of oil and gas in reservoir rocks may cause the variability of biomarkers and uncertainty of conventional studies of oil and gas sources. There are depressions around the Luliang Oil Field, and all the depressions are expected to be the provenances of oil and gas in the oil field. The present study deals with the structural evolution, hydrocarbon-generating capacity, geochemical signatures and evolution of conveying beds in the surrounding depressions. The correlation of the biomarkers such as tritrepane C₂₀, C₂₁ and C₂₃, and sterane C₂₇, C₂₈ and C₂₉ has led us to conclude that the principal sources of the oil in the Luliang Oil Field are derived from the Permian source rocks in the western depression of the Basin-1 well, and those of the gas are derived chiefly from the Jurassic source rocks in the western depression of the Basin-1 well.
