Abstract: Along with more and more volcanic reservoirs discovered , it is necessary to establish volcanic seismic reservoir to meet the urgent needs of petroleum exploration and development. Volcanic seismic reservoir is a branch science of seismic reservoir, and it mainly researches basin tectonic setting, volcanic lithology and lithofacies characteristics, reservoir space type, physical properties, appearance characteristics and the fluid characteristics in three-dimensional space, so as to carry out volcanic reservoir modeling. Multi-disciplinary collaborative research, such as geology, seismics and logging, is the fundamental method for studying the volcanic seismic reservoir. Rock and mineral analysis, logging lithologic identification, reservoir seismic prediction, fluid prediction, reservoir modeling and 3D visualization are six key technologies of studying volcanic seismic reservoir. Volcanic seismic reservoir can be applied to the various stages from exploration to development. However, due to the limited resolution of the existing seismic data, the recognition range of high-quality thin beds of volcanic rock is only 10 mor so, and the research of the reservoir properties and reservoir fluid properties is still in the semiquantitative stage.
