摘　　要：通过对吉林省德惠县境内饮马河（现代曲流河）大榆树林点坝的三维解剖，对曲流河点坝内部沉积特征进行了详细研究。发现饮马河点坝是由一系列侧积体组成的，由于水动力条件的变化和沉积机制的差异，该曲流河点坝内部可发育正旋回、反旋回和复合旋回３种基本类型的侧积体，其形成机制分别为涨冲落淤、涨淤落冲和涨淤落淤。不同类型侧积体的识别与划分，使曲流河点坝储集层描述更为精细，对该类型储集层油田开发、剩余油挖潜具有重要意义。图４照片３表１参６（邹冬平摘）The sedimentary characters of the meandering river point bar reservoirs are studied in detail in this paper on the basis of the three dimensional section of Dayushulin point bar of Yinma river which is a modern meandering river in Dehui county of Jilin province. The study result shows that the point bars are made of a lot of the lateral accretion bodies, and three types of them—positive cycle, negative cycle and complex cycle bodies can exist in meandering river point bars. The distinguishing and the dividing of the different type lateral accretion bodies are significant for oil developing, taping remaining oil potentials and accurately describing meandering river point bar reservoirs.
