摘　　要：松辽盆地是我国一个重要的陆相含油气盆地,其中央坳陷区北部孕育了世界级特大油田——大庆油田。随着勘探开发力度的加强,对盆地储层沉积学方面的研究越来越多。通过梳理松辽盆地中央坳陷区主要油层沉积学方面的研究,从岩石特征、沉积环境与沉积相、物源、沉积体系与沉积模式4个方面进行统计分析,明确了主要储层的岩相类型和岩性特征,以及主要储层的沉积相类型和沉积环境因素对沉积相的控制作用,并讨论了研究区三角洲沉积相的特征;对中央坳陷区的主要物源及目前物源研究的主要方法和不足、中央坳陷区沉积体系的类型和盆地沉积模式演化过程有了进一步认识。Songliao Basin is an important continental petroliferous basin in our country.The world-class oil field Daqing Field is gestated in the north of the central depression.With the development of exploration and development,more and more researches have been done on reservoir sedimentology.Based on the study of the sedimentology of the main oil layers in the central depression area of Songliao Basin,this paper summarizes the characteristics of rocks,sedimentary environment and facies,provenance,depositional system and depositional model,the types of sedimentary facies and the control of sedimentary environment on sedimentary facies are defined,and the characteristics of delta sedimentary facies are discussed The main provenances of the central depression and the main methods and deficiencies of the current provenance research are clarified,and the types of the depositional system and the evolution process of the basin depositional model are also clarified.
