Abstract: Lithology and lithofacies of volcanic rock are very complex, which control reservoirs characteristics. Seven geophysical methods are available for comprehensive study of volcanic rock, while 5 are useful for identification of lithology and lithofacies of volcanic rock.Calculation of reservoir parameters with the established model from the selected framework parameters of different lithologies can improve the accuracy of log interpretation, thereby favoring volcanic rock reservoir evaluation.
