摘　　要：车古 2 0 1潜山油藏为胜利油区近几年的重大发现之一。应用彩色岩心扫描分析仪对该区岩心进行剖切和圆周扫描 ,应用扫描分析软件对裂缝、孔洞进行分析 ,运用FMI测井资料解释结果和铸体薄片、扫描电镜、物性分析等资料 ,对潜山深层储集层特征及其影响因素进行了系统研究。指出该潜山储集层为裂缝 -孔洞型 ,储集层发育受岩性、充填物、构造等因素的影响 ,该潜山有利储集层段为馒头组 ,凤山组 ,下马家沟组中、上段 ,上马家沟组及八陡组一段、二段、三段 ,太古界也有一定的储集条件。Chegu 201 buried hill reservoir is one of the great discovies in Shengli petroliferous area in recent years. The cores of this area are scanned dissectly and circumferentially by color core scanning analyzer. The fractures and vugs are analyzed by applying scanning analytic software. The deep reservoir characteristics of buried hill and its influential factors are studied systematically using interpretation results of FMI log information, and information about cast thin section, scanning electron microscope and physical characteristic analysis. The buried hill reservoir is considered as fracturevugtype. The reservoir development is influenced by the factors of lithology, packing material and structure. The favorable buried hill reservoirs are Mantou group, Fengshan group, middleupper section of lower Majiegou group, upper Majiegou group and 1 2 3 sections of Badou group. The Archean has certain accumulation condition.
