Abstract: In some of the oil auci nas basins of Tertiary in China, there exist immature oils with a certain quantity of reserves. This has been come into our notice. It is indicated by making a study on biomarker coxmpou uds that these immature oils can be carrelated with ixnmatux-e source racks, but different from mature source rocks.

摘要: 在中国某些第三系含油气盆地中,发现了未成熟石油,并具有一定的工业储量。近几年,这已经引起了我国学者的关注。生物标记化合物的研究表明,这些未成熟的石油可以与未成熟的油源岩(其镜质体反射串Ro为0.4-0.6%)对比,而与成熟的生油岩殊异。在这些未成熟的石油中,生物标志化合物的构型参数,均远未达到其异构化的终点,这是用千酩根热降解成烃学说难以作出解释的。我们认为,这些未成熟石汕是从油源岩中可溶有机质在较低温度下直接降解而来。模拟实验表明,未成熟生油岩中的沥青质比干酩根更容易转化为烃类。
