The compositions of organic matter in four immature source rocks from Tertiary strata of Jiyang super-depression, the most typical continental rift subsidence basin in East China, have been stud- ied by different extracting methods with CHCl3, MAC and CS2/NMP, respectively. The results suggest that there are great differences among the chemical compositions of organic matter in the source rocks derived from different depositional environments. About 79% of all the organic matter exists by non- covalent bond in the Es4 source rocks which were deposited under the saline lacustrine, indicating that its organic matter is not the real kerogen, but mainly composed of soluble organic matter which is easy to generate hydrocarbon at lower temperature. This is why the immature oils were derived from Es4 source rocks in Dongying depression. In contrast, around 60% of organic matter exists by covalent bond in Es3 source rocks which were deposited under the deep brackish-fresh lacustrine, showing that Es3 source rocks are mainly composed of kerogen producing mature hydrocarbon at higher temperature. The thermal simulation experiments, upon the remaining solid source rocks which were sequentially extracted by the three solvents, have been carried out. The chloroform extracts from the simulation product have been compared with the other three solvent extracts gained at room temperature. It is obvious that re-markable odd/even predominance (OEP) is mainly the characteristic of soluble organic matter; phytane mostly exists in the soluble organic matter by means of non-covalent bonds and characteristics of soluble organic matter are similar to these in immature oils produced in Jiyang super-depression.

Isotopic composition characteristics and the significance of immature and low-mature oils are first systematically discussed. The carbon isotopes of the whole oil can be divided into two groups, one has δ13C main peak values ranging from -30‰ to -29 and the other from -27‰ to -25‰, they are related to lacustrine and salt-lake facies or swamp facies, respectively. The carbon isotopic fractionation among different group components is relatively small, usually less than 2‰ and the biggest difference in fractionation often occurs between saturated and aromatic fractions. Their δD values vary between -180‰ and -130‰. The main peak of their δD values concentrates between -170‰ and -150‰, suggesting a domination of lacustrine facies. However, the secondary peak ranges from -160‰ to -150‰, showing a frequent salinization of paleo-water bodies. The average δ13C values of the methane vary between -50‰ and -52‰, about 10‰ lighter than those of mature oils. There is a relatively good

The immature calcareous shale in the south slope of Dongying sag, Jiyang depression, plays a significant role in immature oil genesis, and is sampled to make simulation experiment. The geochemical characters of the products of soluble organic matter and kerogen are researched respectively. The yields of the two components and their relations are made out. The contribution ratio between soluble organic matter and kerogen undergoing early degradation in lake facies of semi-salt water is figured out for the first time, so the research into the genetic mechanism of immature oil is developed.

近年来，塔里木盆地的生油研究取得很大进展，根据塔里木盆地烃源岩分布和成熟度研究的结果，作者主要讨论了以下几个问题：①塔里木盆地总资源量可能略低于以前的估算，并且减少的可能只是原油资源量；②塔里木是一个富含天然气的盆地，富气的根本原因是三套烃源岩中两套源岩在晚近期以生气为主；③烃源岩的分布和成熟度决定了台盆区的勘探重点是中、西部地区；④侏罗系源岩是塔里木盆地成为大气区的重要物质基础，应加强在北、西。

Simulation experiment was carried out on all kinds of modern organisms significant to oil-gas generation and the C-isotopic values of n-alkanes in different organisms. The distribution characteristics of individual n-alkane isotopes are studied. The experimental results supply important clues in biological provenance of n-alkanes in sedimentary organisms.

四川盆地西北部龙门山北段东缘矿山梁地区受海西构造运动中产生的断裂和裂缝系统的控制,在矿山梁和碾子坝构造上的寒武系、奥陶系和志留系地层之中分布着众多的沥青脉,是我国和世界上最古老的沥青脉之一。在野外考察的基础上,对沥青脉抽提物的饱和烃和芳烃中沥青分子地球化学特征进行的研究发现,其分子化合物的组成具有某些独特之处,这可能是由于沥青脉源于震旦—寒武系古油藏,当时只有藻类和细菌生源,沥青脉属于热蚀变沥青,形成后经历了长期演化。同时,矿山梁和碾子坝分布的沥青脉也指示在龙门山褶皱带东缘找寻我国最古老的震旦—寒武系油田的良好前景。

This paper studies the evolutional characteristics and the geochemical significance of the immature, mature, highly mature steranes and polycyclic terpanes of the Upper Tertiary in a deep well of Qaidam Basin, on the basis of their compositions and configurations obtained from GC-MS analysis. The informations are further used to determine the threshold depth of main oil generation zone in combination with ESR data, and to identify the source of their precursors in combination with stable carbon isotopic data. It is concluded that the precursors are mainly terrigenous. Pregnane is common in the sample and a complete series of tricyelic diterpanes (C16-C28) is made up after the organic matter becomes mature.

密执安盆地等海相蒸发环境伽马蜡烷的分布表明，伽马蜡烷作为咸水环境的生物标志化合物与高盐度环境并没有绝对的对应关系；松辽盆地淡水－微咸水环境较高含量的伽马蜡烷表明其形成与湖海沟通引起的水体分层事件有关。伽马蜡烷重碳同位素值及微生物学证据均表明了伽马蜡烷的形成与水体分层有关，由于高盐环境往往伴随着密度分层，从而解释了伽马蜡烷经常与高盐环境伴生，但并不仅仅局限于高盐环境的现象。
