摘　　要：结合区域资料,对研究区94口钻井资料进行分析,并利用储层划分与对比的方法对白于山区长2油层组进行地层划分与对比,将长2油层组划分为3个亚层以及6个小层。通过对长2油层组进行地层划分与对比,为后期研究构造特征、沉积相和砂体展布规律、有利区预测及油田开发有十分重要的意义。In combination with regional data,this paper analyzes the data of 94 wells in the study area.With the deepening of oil and gas exploration and development in Baiyushan area,the requirements for fine stratigraphic division and correlation are increasingly refined.The stratigraphic division and comparison of the Chang 2 oil layer group in the Bai yu shan area were carried out by using various method.Chang 2 oil-bearing formtion can be divided into two small layers,such as Chang 211,Chang 212,,Chang 213,,Chang 221,Chang 222+3,Chang 23.Chang 2 oil layer group is stable,and the thickness of each small layer changes lit-tle.The stratigraphic division and comparison of the Chang 2 oil layer group provides basic data for the later study of structural characteristics,sedimentary facies and sand body distribution,predicti-on of favorable areas and oilfield development.
