摘　　要：根据龙门山北段矿山梁地区钻井资料及实验数据,研究下二叠统栖霞组、烃源岩条件、储层特征及圈闭类型特征,认为栖霞组烃源条件丰富,储层主要发育裂缝-孔隙型储集层。储集空间以次生成因的晶间孔、晶间溶孔和溶洞为主。储层的形成与演化主要受沉积作用和成岩作用的影响。最有利于储层形成的沉积相带为台地边缘及台内的浅水高能生屑滩;最有利于储层形成的是白云岩化、溶蚀、破裂作用等建设性成岩作用,分析矿山梁地区油气成藏条件及富集规律。According to the drilling data and the results of the analysis of the Kuangshanliang area in the northern Longmen mountain,the paper studies the reservoir,source rocks and trap characteristics of lower Permian Qixia formation.The result shows that it has abundant source rocks and fracture porosity reservoir.The reservoir space is mainly with secondary origin of intergranular pore,dissolved pore and karst cave.The formation and evolution of reservoir are influenced by sedimentation and diagenesis.The most conducive sedimentary facies to the formation of reservoir is the platform margin and in-platform biological beach,and the most conducive diagenesis to the formation of reservoir is dolomitization,dissolution and cataclasis,summarying petroleum migration and accumulation conditions.
