摘　　要：利用岩心观测、薄片鉴定及录井、钻井等资料 ,对月海油田古生界古潜山储层特征进行了分析研究 ,并对其含油气情况进行了评价。结果认为 :本区古生界古潜山岩性以碳酸盐岩为主 ,沉积相为滨浅海相 ;古潜山储集空间以风化溶蚀型网状裂缝为主 ;通过对 7项油气评价指标的衡量 ,本区古潜山基本属Ⅰ～Ⅱ类古潜山 ,是一个勘探潜力较大、远景看好的古潜山区。Palaeozoic buried hill reservoirs in Yuehai oilfield have been analyzed and studied,and their oil-bearing conditions have been evaluated through core observation,thin section identification,and mud logging and drilling data.The result is that in this palaeozoic buried hill area,major lithology is carbonate,the sedimentary environment belongs to littoral and neritie facies;buried hill reservoir space is mainly weathered,solution network fractures;after evaluation of 7 hydrocarbon indexes,it is determined that most buried hills in this area belong to type I II;so that this buried hill area has great exploration potential and prospective future.
