摘要

///According to analysis of the ages and lithology of parent rocks in volcanic reservoirs, the types of reservoir space and lithofacies of volcanic rocks, which distribute in the basins all around the paleo-Asian tectonic domain of China, the paper discusses the reservoir characteristics and difference of volcanic oil and gas pool. In the paleo-Asian tectonic domain of China, the research indicates that the parent rocks in volcanic reservoir develop in a regular pattern, western parent rocks age is older than eastern.  The effusive facies develop primary pores and structural fracture.  Explosive facies develop intergranular pore; Inter-breccia pore and primary fracture are dominant in the extrusive facies. Several factors affect the difference of volcanic reservoir, such as lithology and lithofacies, eruption environment, late reformation and diagenesis. The first two factors control the formation and distribution of volcanic reservoir and development of reservoir space; the rest reform storage property and permeability of the reservoir.
