摘　　要：梁家楼扇体的成因解释反映了沉积研究的进展,低位扇体成因是最新的成果。在总结前人研究的基础上,通过对经典层序地层学理论中低水位沉积体系域认识的讨论,分析扇体的沉积特征,重新解释梁家楼扇体的形成与构成,指出当前研究的梁家楼扇体为下切水道充填沉积与斜坡扇,真正的盆底扇可能尚未发现。Origin interpretation of 'Liangjialou segments' reflects the progress of sedimentary research,and origin of lowstand segments is the latest achievement. Based on the former research and the discussion of the lowstand sediment system tract in the classic sequence stratigraphy, sedimentary characteristic of the segment was analyzed and the genesis of the 'Liangjialou segments' was reinterpreted. It points out that the' Liangjialou segments' is the downcutting channel fill and slope fan, the true basin- floor fan had not been found yet probably.
