摘要
Based on volcanic lithology, lithofacies features, porosity type, reservoir physical property and etc., volcanic reservoir characteristics of Carboniferous-Permian in Zhongguai-Wubaqu of northwest margin in Junggar basin are studied. The results show that: the volcanic reservoir is mainly volcanic tuff in eruptive facies, andesite and volcanic breccia in effusive facies; secondary pore is the main pore type; the main storage and accumulation space types of the volcanic reservoir are residual pores, intracrystalline pore and structural fracture. Volcanism, tectonism and dissolution are the main influencing factors of reservoir physical property.
