摘　　要：北三台地区石炭系井下钻遇岩性主要包括安山岩、火山角砾岩和凝灰岩,火山岩相以爆发相为主。根据岩心和镜下分析,工区的储集空间类型主要包括气孔、粒内孔、粒间孔和裂缝。同时探讨了工区储集空间的形成机制及演化过程。在此基础上,根据圈闭特征、油源分析、时空关系等因素,确认本工区成藏模式主要以断裂-背斜型油藏模式为主。In Beishantai area, drilling Carboniferous encounters mainly andesite, volcanic breccia and eruptive tuff, and with NATURAL GAS EXPLORATION & DEVELOPMENT/Jan. ,2011the explosion facies as the soul for volcanic rock. In this paper, based on core analysis and microscopic observation, it is found that( 1 ) the reservoir space in study area is mainly composed of stomata, intregrannular pore, intergrannular pore and fracture; (2) theforming mechanism and evolution of the reservoir space are discussed; (3) that the main reservoir-forming mode is fractured-anticlinal reservoir mode is determined according to some data from trap characteristics, oil resource and time-space assembly.
