本文以松辽盆地中央坳陷的大量声波时差—深度资料为基础，首先介绍了本区的泥岩压实作用，指出其在纵剖面上存在着正常、混合及紧密三个压实带，并比较详细地论述了混合压实带跟油气生成、运移和聚集有着密切联系。在此基础上，讨论了油气初次运移的主要时期和方向，并得出松辽盆地的三个含油组合中，以中部组合为最好，其次是下部组合，上部组合较差。下部组合中的扶余油层，在三肇及其外围地区的含油性可能会更好一些。
Based on the large amount of acoustic time difference-depth data in the Central Depression of the Songliao Basin, the paper first introduces the compaction of mudstone in this area, and points out that there are three normal, mixed and tight compaction zones in the longitudinal section It discusses in detail that the mixed compaction zone is closely related to the formation, migration and accumulation of oil and gas. On this basis, the main periods and directions of the primary migration of oil and gas are discussed. It is concluded that among the three oil-bearing combinations in the Songliao Basin, the middle combination is the best, the lower one is the lower combination and the upper combination is poor. The Fuyu reservoir in the lower part may be more oily in Sanzhao and its outlying areas.
