摘要: 利用岩心、薄片、扫描电镜等多种分析手段,从火山岩岩性、岩相特征、孔隙类型、储层物性等方面研究了准噶尔盆地陆东地区石炭系火山岩储层特征,分析了火山岩储层储集空间类型、物性特征以及储层物性的影响因素。研究结果表明:区内火山岩储层主要为基性、中酸性岩类;孔隙类型主要为次生孔缝;储集空间为气孔、残余孔、溶蚀孔、裂缝等;储层物性影响因素主要有火山岩的岩性、岩相、喷发环境及后期风化淋滤和断裂改造。油气成藏主要受石炭系滴水泉组和二叠系平地泉组两套烃源岩控制,在石炭系火山岩储层中形成了自生自储型和上生下储型油气藏。

Abstract: The reservoir characteristics including lithologic characteristics,lithofacies characteristics,pore type,reservoir physical property of the Carboniferous volcanic rocks in Ludong area of Junggar Basin were analyzed by observing core and thin slice with microscope and scanning electron microscope.The reservoir accumulation type and the main affecting factors of reservoir physical property were also analyzed.The results indicate that the volcanic rocks reservoir are mainly composed of the basic rocks,intermediate rocks and acidic rocks,and reservoir accumulation type are the secondary pore and fissure including gas pore,relict pore,emposieu and fissure.The physical property of reservoir was affected by the lithologic characteristics,lithofacies characteristics,eruptive condition,erosion,eluviations and fault reconstruction in the later stage.Two types of source rocks including the Carboniferous Dishuiquan Formation and the Permian Pingdiquan Formation controlled the oil and gas reservoirs.The authigenetic self-stored reservoirs and upper-genetic down-stored reservoirs were generated in the Carboniferous volcanic rocks.

Key words: Junggar Basin, Carboniferous, volcanic rocks reservoir, secondary pore and fissure, oil accumulation model
