| 摘 要： | Volcanic rocks of the late Mesozoic are very important reservoirs for the commercial natural gases including hydrocarbon, carbon dioxide and rare gases in the northern Songliao Basin. The reservoir volcanic rocks include rhyolite, andesite, Wachyte, basalt and tuff. Facies of the volcanic rocks can be classified into 5 categories and 15 special types. Porosity and permeability of the volcanic reservoirs arc facies-controlled, Commercial reservoirs were commonly found among the following volcanic subfacics： volcanic neck （Ⅰ1）, underground-explosive breccia （Ⅰ3）, pyroclastic-bcaring lava flow （Ⅱ3）, upper effusivc （Ⅲ3） and inner extrusive ones （ Ⅳ1）. The best volcanic reservoirs arc generally evolved in the interbedded explosive and effusivc volcanics. Rhyolites show in general better reservoir features than other types of rocks do.
