摘要

Volcanic rock is the most important deep gas reservoir in Songliao Basin. The mineralogical characteristics and physical property characteristics, pore type and genesis, relationship of rock facies and physical propcries of volcanic reservoir rock are systematically studied, and the result shows that the secondary pores in volcanic rocks not only increase the effective storage space, but also play a critical role for connection of primary pore. The secondary pores are the precondition of volcanic rocks in Songliao Basin becoming effective reservoirs. The development degree of secondary pores can be reflected by the ratio of total porosity of volcanic rock to effective porosity from core analysis.
