【摘要】 对歧口凹陷火山口相、爆发相、溢流相、浅成侵入相、次火山岩相、火山通道相及火山沉积相等多种火成岩岩相的测井、地震反射特征进行了归纳总结,并对不同岩相火成岩的储集空间类型及储集性能的影响因素进行了综合分析,结果表明:岩相是影响储集性能的主要控制因素,随火成岩相带不同,其储集物性也不相同。其中,溢流相、爆发相含有大量的气孔、砾间孔缝,储集性能好,而次火山岩相、溢流相中部的致密带与侵入岩相似,原生孔缝不发育,储集性能较差;一些外部作用因素也会对火成岩的储集性能产生较大的影响。更多还原

【Abstract】 In this paper,we concluded the features of logging and seismic reflection about different lithofacies of igneous rock(crater,eruption,effusion,shallow invasion,secondary volcanic,volcanic vent,volcanogenic,etc.).We also discussed comprehensively the factors controlling types of reservoir space and ability of reservoir accumulation in different lithofacies igneous rock.The results indicate that the lithofacies would be the main factor to affect the ability of reservoir accumulation.The different lithofacies of igneous rock are associated with the different physical property of reservoir.The external action also affects the different physical property of volcanic reservoir.The correlation between lithofacies of igneous rock and reservoir space will make a significant role to guide the igneous exploration in this area.更多还原
