Volcanic reservoir is usually of dual porosity medium character. The reservior spaces can be classified into two genetic categories: primary reservior spaces (PRS) and secondary reservior spaces (SRS). Based on extensive identification and description of casting thin section, this paper divided the PRS of Carboniferous igneous rocks in Dixi area into five types of primary pores (gas pores, residual amygdale, intergranular pores, intragranular pores and intercrystal pores) and four types of primary fractures (shrinkage joint, explosive fracture, intergravel crack and intercrystal crack). The study of the formation mechanism of igneous PRS can reveal the distribution of SRS and is of great significance in the prognosis of favorable reservoir zones.
