摘　　要：以杏6区块为研究区,在研究测井资料、岩心资料、动态生产资料的基础上,运用高分辨率层序地层学对比技术,从沉积学角度,系统论证该层的两分性,即该层为2个河流期沉积复合体.系统分析复合砂体内部剩余油分布特征,每期河道砂体内都具有各自的垂向水淹特征,即总体上底部高水淹,向上水淹程度逐渐变弱至未水淹.为该区的单砂体建筑结构研究及提高采收率提供依据.This paper takes Xing 6 block as the target area,on the basis of logging data,the core information,dynamic production information,with high-resolution sequence stratigraphy demonstrating two-separability of PⅠ33 systematically from the angle of sedimentology,namely,this layer is a sedimentary complex of the two river stage.We have analyzed the characteristics of remaining oil in the compound sand body.Each channel sand body has its own respective characteristics in the vertical water flood.As a whole at the bottom,the extent of water flood is high,and it weakens gradually until non-flooded with the level raising.It provided the basis for the study of the single sandbody architecture and the advance of the recovery ratio.
