摘要(Abstract)：

准噶尔盆地哈山地区紧邻玛湖富生烃凹陷,是油气运移和聚集的有利指向区.为认识哈山地区石炭系火山岩储层特征及主控因素,利用岩心、薄片及成像测井手段,分析火山岩岩石学特征、储集空间类型、储层物性特征等,研究哈山地区石炭系火山岩储层特征及储集性能主控因素.结果表明:研究区内火山岩岩石类型复杂,主要为火山角砾岩、安山岩、凝灰岩和玄武岩;储集空间类型主要为次生溶孔、裂缝及少量原生孔隙(砾间孔和残余气孔);储集性能较差,以中低孔—低渗(特低渗)储层为主,非均质性强,火山角砾岩物性最好,是石炭系最有利的储集层,其次是安山岩和凝灰岩,玄武岩储集性能最差;储集性能影响因素主要有火山岩的岩性、岩相、构造活动及溶蚀作用.该研究结果对准噶尔盆地哈山地区油气勘探开发具有指导意义.
