方法　应用钻井、测井、地震及化验等资料 ,对龙湾筒凹陷九佛堂组火山岩储层特征进行了研究。目的　指明有利的火山岩储集相带及储集空间 ,进行储层评价。结果　本区火山岩最有利的储集相带是溢流相上部和下部气孔发育带 ,最有利的储集空间是多气孔、多裂缝型。结论　龙湾筒凹陷九佛堂组火山岩分布广泛 ,且具有形成中小型油藏的能力 ,是辽河油区外围盆地勘探的新领域。 Methods The drilling, logging, seismic and laboratory data were used to study the volcanic reservoir characteristics of the Jiufotang Formation in Longwangou Depression. Purpose Indicate favorable volcanic reservoir facies belt and reservoir space for reservoir evaluation. Results The most favorable reservoir facies in the volcanic rocks in this area is the upper and lower stomata of the overflow phase. The most favorable reservoirs are multi-porosity and multi-fracture types. Conclusion The volcanic rocks in the Jiufotang Formation in Longwangou depression are widely distributed and have the ability to form small and medium reservoirs. It is a new area for exploration in the peripheral basins of Liaohe oil province.
