摘　　要：储层特征研究是评价碳酸盐岩储层物性、寻找油气富集区和落实剩余油分布的基础,通过对区域构造、地层和沉积特征的研究,利用统计和数学方法对Bakr—Amer油田Eoc储层物性、储集空间类型和控制因素进行了分析,认为受构造运动影响,储层在深部残余厚度大,但物性相对也较差,以压实、胶结和溶蚀作用为主。高部位残余厚度小,但受风化、淋滤和构造运动的影响,裂缝发育,储层物性好,以压实和溶蚀作用为主。The study of reservoir properties is significant for searching the hydrocarbon rich region and remaining oil.The Eoc Formation of the Bakr—Amer Field,Egypt is characterized by carbonate reservoirs.Based on the research of regional structure,stratigraphy and sedimentary features,statistical and mathematical methods are adopted to study the petrophysics,reservoir space types and controlling factors.Affected by tectonic movements,the residual reservoir in the deeper part is thick,but the porosity is relatively low due to compaction,cementation and dissolution.In the upper part,however,the residual reservoir has good reservoir properties,but is thin in thickness due to weathering,leaching,dissolution and fracture growth.
