Large oil-gas fields with over 100 million tons of yield have been recently discovered in volcanic rocks in Songliao basin and Dzungaria basin. This paper, based on the geology and distribution of oil-gas reservoir in volcanic rocks, analyzes the status of oil-gas resources hosted in volcanic rocks, forecasts the prospect in some blocks to be discovered. It concludes that volcanic-hosted oil-gas reservoir is of great prospect to be explored as a new vital field in the future.
