扶余X10-2区块点坝储层构型刻画及剩余油分布

摘要

点坝是曲流河沉积的主体,点坝内部构型的描述是曲流河研究的重点.以A.D.Miall的层次界面分析法为指导,对扶余X10-2区块曲流河点坝砂体内部建筑结构进行刻画.曲流河点坝单砂体构型刻画研究为油藏分析建立更为精确的三维地质模型,形成对剩余油富集规律的新认识,为更准确查找剩余油分布提供了有利依据.%Point bars constitute the main part of meandering river deposition, and the description of its inner structure is essential in meandering river research. With the guidance of A. D. Miall' s hierarchy interfaces, the internal architecture of point bar sands in the meandering river deposition in Fuyu X10 - 2 block has been described. The delineation of per - sand body structure in point par of meandering river is helpful to the establishment of precise 3D geological model and the recognitionTmd location of residual oil distribution.
