Abstract: This article discussed log curve response characteristics of various rock types in Changtu depression based on its identification materials under rock core lens, established lithology interpretation models and confirmed the calculation methods for reservoir physical property parameter according to rock core laboratory tested analysis materials. Aiming at the characteristics of fracture pore double cubage among volcano elastics rock, and base on the logging interpretation theory, it discussed interpretation methods for volcano elastics rock physical property and provided more reasonable and more accurate parameters for reservoir evaluation.
