Fig. 10. Distribution of physical properties of Permian pyroclastic rock from Well YT1.9Comparison of eruption facies pyroclastic rock and overflow facies basalt shows they have apparent differences in reservoir properties, and pyroclastic rock has better reservoir property among the igneous rocks, a special kind of reservoir rock, in Sichuan Basin.
