摘要

The gas-bearing volcanic rocks of Qingshen gas field in the Songliao Basin consist of rhyolite, ignimbrite, tuff, agglomerate, andesite, dacite, trachite, most of them belong to middle-acidic volcanic, and the mainly gas reservoir rocks are rhyolite and tuff, which is different from other volcanic reservoir of oil and gas fields in China. The developments of volcanic reservoirs in different areas associate with the location of volcanic rocks. Volcanic apparatus distribute along the fault zones. The multi-lithofacies superimposing areas around volcanic crater, and the eruption and effusion facies near volcanic crater superimposing areas have better reservoir properties, and these areas are the favorable gas exploration target.
