Volcanic gas reservoirs in eastern Changling depression are characterized by large scale reserves, high abundance, good physical properties and high single-well production, and are the main area of deep gas exploration. The analysis on the key elements of the volcanic gas reservoirs reveals that the major source rocks are dark mudstone and coal layers of lacustrine and paludal facies of Lower Cretaceous Shahezi Formation. The major reservoirs are neutral and acid volcanic rocks on top of the Yingcheng Formation, and the reservoir space is induced pores and fractures. Fault and uncomformable surface are the main path for hydrocarbon migration. According to the characters of volcanic gas reservoir, three kinds of reservoir forming models are generalized, they are structure\|type reservoir forming model, structure-lithology type reservoir forming model and lithology-type reservoir forming model. Structure-lithology type is the most important pattern.
