摘要
北三台地区石炭系火山岩地层作为储层的岩性主要包括安山岩、玄武岩、火山角砾岩以及凝灰岩,详细叙述了其岩石学特征,同时阐述了对该地区储层产生影响的主要因素。在对火山岩孔渗基本特征,孔隙结构和孔渗关系的研究基础上,对储层进行综合评价,将其分为5类,较好的火山岩储层平面分布呈带状或块状分布,西地一号背斜带及台50井阜康断裂东部区域储层类型级别较高,台48井以南和吉木萨尔凹陷为较差区域。
The main lithology of Carboniferous volcanic reservoirs in the Beisantai area includes andesite,basalt,breccia and tuff. This paper makes fully account of the petrological characteristics and the principal factors influencing the reservoirs in this area. The reservoirs are evaluated and classified into 5 categories based on the study of porosity and permeability,pore configuration and porosity-permeability relationship. Favorable reservoir distribution presents as banded and lump deposits. The Xidi No.1 anticline and the east of Fukang fault in the Well Tai 50 are of higher reservoir class,while the south of the Well Tai 48 and the Jimsar depression are unfavorable areas.
