本文以构造运动为线索,考虑到松辽盆地进入坳陷时期的沉积相变迁,用有机地球化学指标,描述了有机质的分布。进而,根据高古地温场的条件,论证了盆地有机质向烃类演化的相带具有浅门限薄相带的特征。根据整个建造的生油岩分布状态,提出了生油体概念。对比海陆相原油特征,讨论了盆地高蜡低硫等陆相原油性质。
In this paper, taking the tectonic movement as a clue, taking into account the Songliao Basin into the depression during the sedimentary facies changes, using organic geochemical indicators, described the distribution of organic matter. Furthermore, according to the conditions of the paleo-geothermal field, it is demonstrated that the facies belt of organic matter-to-hydrocarbon evolution in the basin is characterized by a shallow threshold thin facies belt. According to the distribution of the whole source rock, the concept of oil body is proposed. Comparing the characteristics of marine and marine crude oil, the properties of continental oil such as high wax and low sulfur in the basin are discussed.
