Discussion on Volcanic Rock Reservoir Structure-Genesis Classification

Traditional classifications of volcanic rock emphasize the connotation of petrography and poorly relate to reservoir spaces, which cannot meet the need for reservoir studies with respect to the oil and gas exploration. Based on the analyses of reservoir space types, combinations and genetics of volcanic rock, six factors that are closely related to reservoir spaces are summed up. Combining with the traditional classification schemes and previous knowledge, a new classification scheme of volcanic rock reservoir in oil and gas exploration is set up.
