摘　　要：沉积微相分析是建立油藏地质模型及进行油藏综合评价的基础 ,正确描述砂体成因类型、几何形态及空间分布规律 ,对于指导油田进一步开发 ,具有十分重要的意义。本次主要研究该区 1～ 6砂层组沉积环境 ,从影响剩余油分布的因素入手 ,以岩心为基础 ,以开发时间为主线 ,综合多学科信息 ,提出剩余油分布及挖潜方向 ,揭示同类油田的剩余油形成及分布规律 ,最终达到改善开发效果 ,进一步提高采收率的目的。The analysis of depositional micro-facies is based on geological model and the comprehensive evaluation of the reservoir.It is very important in the further development of the oilfield to describe the original types,geometric configuration and distributed laws of sand body.This paper primarily aims at studying the depositional environmental of S_ 1-6 on the basis of core and in the main line of production periods,starts from the factors of effecting the distribution of residual oil and combines with the multi-science information.Thereby,the article puts forward the distribution of residual oil and the way of tapping potential and discloses the formation and distributed law of residual oil within the similar oilfields.Oilfield can be exploited and developed more efficiently and recovery efficiency can be further improved and promoted at last.
