     The characteristics of thermal evolution of organic matter have some small differences between source rocks from Jurassic measures strata of Northwest China and from non coal forming lacustrine basins, but their models of oil generation are essentially similar. Main oil window of coal bearing organic matter is from 0.7% to 1.2% of vitrinite reflectance, but the peak of oil generation is around 0.95%, and a little earlier than the lacustrine organic matter.

The Subei basin is a relatively complicated faulted-depressed petroliferous basin, and assessment of thermal evolution level of organic matter in Paleogene source rocks in the basin is still unsolved.By using optical index of maceral and chemical index of soluble organic matter,the characteristics of thermal evolution of organicmatter from Paleogene source rocks in the Subei basin are studied systemically. A disequilibrium and stagging of thermal evolution are revealed. It is suggested that the vitrinite reflectance should be the most reliable indicator to represent thermal evolution level. Fluorescence alteration of sporinite and alginite shows a special significance for thermal evolution. The evolution characteristics of soluble organic matter are basically consistent with those of maceral. Through the comprehensive analysis, it is proposed that the evolution stage of organic matter in the Subei basin can be divided into stage.Ⅰand stage Ⅱ, and the transtion from stage Ⅰto stage Ⅱ occurs about 0.60% ̄0.65% in vitrinite reflectance.

苏北盆地是一个较为复杂的断陷-坳陷型合油气盆地,对其早第二纪烃源岩有机质热演化程度的评价是目前尚未解决的课题。应用显微组分光学标志和可溶有机物化学标志,研究了苏北盆地早第三纪烃源岩有机质热演化特征、从而揭示了有机质热演化的不均衡性与阶段性。该盆地烃源岩的镜质组反射率Ro是最可靠的演化标志;孢子体和藻类体的荧光变化特征具有特殊重要的演化意义.正构烷烃分布特征和甾、藿烷异构体比值的演化趋势与显微组分的光性演化完全吻合。综合各种光学和化学标志,将苏北盆地有机质演化划分为阶段Ⅰ和阶段Ⅱ两个演化阶段,其阶段转折处的Ro在0.60%~0.65%之间。

In the Jurassic coal measure source rocks, main macerals of hydrocarbon generation are sporinite, cutinite, alginite, bituminite, liptodetrinite and desmocollinite. Suberinite and resinite are extremely low concentration, which are generally regarded as the macerals generating hydrocarbon in immature and low mature. The characteristics of thermal evolution of organic matter have some small differences between source rocks from Jurassic measures strata of Northwest China and from non coal forming...

In the Jurassic coal measure source rocks, main macerals of hydrocarbon generation are sporinite, cutinite, alginite, bituminite, liptodetrinite and desmocollinite. Suberinite and resinite are extremely low concentration, which are generally regarded as the macerals generating hydrocarbon in immature and low mature. The characteristics of thermal evolution of organic matter have some small differences between source rocks from Jurassic measures strata of Northwest China and from non coal forming lacustrine basins, but their models of oil generation are essentially similar. Main oil window of coal bearing organic matter is from 0.7% to 1.2% of vitrinite reflectance, but the peak of oil generation is around 0.95%, and a little earlier than the lacustrine organic matter. In Jurassic basins of Northwest China, the current maturity of organic matter is generally from R o 0.4% to 1.3%, but majority of them has lower maturity. In some piedmont basins or depressions of the area, the organic matter in source rocks has higher maturity, and the vitrinite reflectance ( R o) is great than 0.7%, beginning to generate large amount of crude oil. In the Jurassic coal bearing basins of Northwest China, oil fields generally distribute in these areas having higher mature source rocks. This indicates that maturity of source rocks prominently controls petroleum generation and occurrence of oil fields. The prospective areas of hydrocarbon generation usually locate in the piedmont regions that had been the centers of subsidence and deposition during Jurassic period, and then consequently were deeply buried after Jurassic.

西北地区侏罗纪煤系中主要成烃显微组分是孢子体、角质体、藻类体、沥青质体、碎屑类脂体和基质镜质体等,木栓质体和树脂体等早期成烃组分含量极低。侏罗纪煤系有机质成烃演化特征与一般湖相有机质稍有差异,但基本上仍然遵循一般有机质热降解成熟生油模式,主要生油阶段的Ro值为0.7%~1.2%,生油高峰Ro值约为0.95%。目前西北地区侏罗纪煤系烃源岩Ro值一般为0.4%~1.3%,多数地区成熟度较低,在山前深坳陷地区成熟度较高,烃源岩Ro值大于0.7%,进入大量生油阶段,西北地区主要煤系含油气盆地油气田均分布于这些地区,烃源岩成熟度对油气田形成有明显的控制作用。西北地区侏罗系有利的生烃区域基本分布在侏罗纪是沉降、沉积中心而后续埋藏又较深的山前坳陷。图4表1参45(王孝陵摘)
