Abstract：The volcanicrocksof theCarboniferous BashanFormationarewidelydevelopedintheShazhang fault-foldbelt in easternJungaerBasinandtheexplorationanddevelopmentofthecarboniferousvolcanicgasfieldintheadjacent WucaiwanSag indicates thatthecarboniferousvolcanicocks inthestudyareaalsohavethepotentialofreservoirformation.Toprovidesupport forvolcanicoilandgasexplorationinthisarea，thispapercomprehensivelystudies techaracteristicsofvolcanicreseroirsand theirinfluencingfactorsbyusingdrlling，rocksample，themicroscopicchipimaginglogging，analysisdata.Theresultsshow that：1）volcanicrock reservoir lithologyofBashan Formation is mainlycomposedofvolcanic lava，fused volcanic breccia， pyroclasticrock，volcanic-sedimentaryrockandsub-volcanicrock，whichcanbeidentifiedaseruptivefacies，overflowfacies， volcanic-sedimentary facies;2）themainreservoirspace is primaryreservoir space（primarypores）and secondaryreservoir space （secondary pores and fractures），and there are four types of reservoir space combination：pore + dissolved pores in almond body + fracture，pore + dissolution pore，dissolution pore + fracture and fracture;3） the volcanic rock is of medium-low porosityand mediumpermeabilityreservoirwith pooroverallphysical propertyandheteroqeneity;4）thedevelopmentof favorablevolcanicreservoir inBashanFormation is mainlycontroledbylithologyandlithofacies，weatheringandleaching， and tectonic fragmentation.
