- Some advances in organic petrology studies on immature source rocks
低熟烃源岩有机岩石学研究的若干进展 - Based on the maturity , organic matter richness , organic type of source rocks , following order have been proposed based on quality of source rocks : 2 ) the curve between tmax and depth has been established . from the data of different wells , it indicates that most of the source rocks in this region belong to immature source rocks . the data also reflect the early generation of hydrocarbon in the source rocks
取得的主要成果如下： 1 、通过综合分析德南洼陷烃源岩品质、生烃潜量、有机质类型和丰度，得出研究区沙一段和沙三段为好-较好烃源岩，有机质以-型有机质为主，生烃潜力较强；沙四段烃源岩为较差-较好烃源岩，有机质类型变化较大；沙二段有机质类型差，生烃潜力十分有限，为非烃源岩。 - This study used some techniques such as organic geochemistry bulk composition combined with molecular geochemistry , source rock analysis and evaluation of organic petrology , carbon isotopes of organic matter , petroleum geology inference etc . the emphasis is mainly concentrated on the source rocks belong to the shahejie formation of pal eocene , including the source rock evaluation of denan region , geochemistry of the source rock , biomarkers of immature oils and source rocks . then the ancient geological environment was established and immature oil formation mechanism was proposed . following results have been tentatively proposed in this thesis : 1 ) based on the organic petrology studies , most of source rocks in this region is belong to immature source rock
本项研究以德南洼陷重点烃源岩- - -下第三系沙河街组为对象，应用有机地球化学理论与方法对其有机质类型和丰度、成熟度、生烃潜量等进行研究；通过特征生物标志化合物的分析，阐明研究区未熟-低熟烃源岩母质构成、沉积环境和成熟演化；通过油源对比和生烃条件综合分析，提出本区烃源岩生烃机制，建立未熟-低熟烃源岩有机质生烃模式。 - 4 ) the characteristic of tricyclic terpane reflected the source input of algae . the predominance of 4 - methylsterane and dinosterane , and the c _ ( 27 ) - sterane predominance " v " distribution pattern all indicate the great contribution of algae source input . based on the ratio of sterane c2920s / ( 20s + 20r ) and c29 / ( + ) , the source rocks can be regarded as typical immature source rocks
2 、利用丰富的生物标志化合物信息，分析解释了生源构成、沉积环境、有机质演化等特征，表明德南洼陷主力烃源岩的生源构成是以菌藻类微生物为主且含有一定陆生植物输入的混合生源，沉积环境为半咸水-咸水还原环境，沉积水体具有“层状”特点，表层盐度高，底层还原性强。
