摘要

文中应用生物标志物分析技术并结合其它地球化学资料,对安参1井侏罗系和石炭—二叠系暗色泥岩的有机地球化学特征进行了初步分析。结果表明,两套暗色地层有机质丰度较低,有机母质主要为低等水生生物,兼有高等植物混入,有机质类型为腐殖-腐泥型,有机质热演化成熟度很高,生油气高峰已过,但仍可作为该区的气源岩。

Abstract

Organic geochemical characteristics of the Jurassic and Carboniferous-Permian melamudstone in well An'can-1 were studied preliminarily by means of the biomarker analysis technology combined with other geochemical data. The results revealed thet two sets of dark strata have lower organic matter abundance, their organic mother matter is dominated by low-grade hydrobios mixed with high-grade plants, and the type of organic matter is humosapropelic. The high maturity for the thermal evolution of organic matter shows that the hydrocarbon-generating peak has gone, but the strata can still be gas source rock of the area.
