　　通过岩心观察、显微鉴定、扫描分析和成像测井等对准噶尔盆地火山岩油气储层的储集空间进行系统分类并分析其组合特征。结果表明，准噶尔盆地火山岩储层的储集空间可划分为原生孔隙、次生孔隙和裂缝3大类，进一步可细分出4种原生孔隙、5种次生孔隙和4种裂缝。其中，次生孔隙和裂缝对火山岩储集性能的改善具关键作用；储集空间组合类型包括构造缝-溶蚀缝-溶孔组合、原生气孔-构造缝-溶蚀缝-溶蚀孔组合和晶间孔-原生孔-构造缝-溶蚀孔组合等3种类型；孔缝组合整体表现为类型多样、形态各异、结构复杂、分布不均、连通性差、裂缝改善明显等特点。

Integrated with core observation, microscopic identification, scanning analysis and imaging logging, this study classified reservoir spaces of the Carboniferous volcanic rocks in the Junggar Basin and described their assem-blage characteristics. The results indicate that volcanic reservoir includes three main space types:primary porosity, sec-ond porosity and fracture, which can be divided further into 4 types of primary porosity, 5 types of second porosity, and 4 types of fracture, and the latter two space types play significantly important roles in improving volcanic reservoir prop-erty. Three assemblage models of reservoir spaces are identified:structure fracture-dissolution fracture-dissolution po-rosity;primary pore-structure fracture-dissolution fracture-dissolution porosity;intercrystalline pore-primary porosi-ty-structure fracture-dissolution porosity. The assemblages of reservoir spaces are characterized by the diversities of type, geometric configuration, distribution and structure as well as low connectivity and highly fracture improving.
