Volcanic oil and gas reservoir geology:Thinking and forecast

The volcanic reservoir in China is characterized by rich residual resources and large potential of petroleum exploration, and will be an important field for the future oil and gas exploration and development. The research emphases of volcanic reservoir are lithology, lithofacies classification, the naming standardization, the formation and evolution mechanism, and the main controlling factors for reservoir development, among which the development characteristics and distribution rule ofvolcanic reservoir are the key. The geologyofvolcanic reservoir is a comprehensive geological subject to study the tectonic setting, genetic type, characters, formation, evolution, geometric shape, distribution rule of the volcanic reservoir, and the reservoir research method and description technique, as well as the reservoir evaluation and prediction. The development of the volcanic reservoir geology is helpful to the establishment of theory system and method system and the development of deep research of volcanic reservoir. The research key fields of volcanic reservoir in sedimentary basins in China include: lithology characteristics and distribution, the diagenesis type and evolution sequence, the origin mechanisms of the weathering crust reservoir, inner buried hill reservoir and fractured reservoir, the evaluation and prediction technique, and the geological modeling and development reservoir evaluation ofvolcanic reservoir.
