Mechanism and Method of the Volcanic Lithofacies Identification in Xujiaweizi Area
摘要
Abstract
In the exploration and development of deep volcanic rocks in Xujiaweizi fault depression ,the recognition accuracy of lithofacies is one of the key factors that determine the success or failure of volcanic reservoir prediction .Although well logging data has rich information and high resolution ,there is no method to identify volcanic lithofacies with well logging data . According to the characteristics of volcanic rock in Xujiaweizi area and based on geological theory ,a lot of cores ,wafer analysis ,conventional and image logging data are used to study the mechanism of natural gamma , density , neutron and image logging and volcanic lithofacies identification .Then with sensitive logging information , the classifications are determined by logging data to identify volcanic lithofacies . Well logging identification method of volcanic lithofacies is established .5 lithofacies and 11 sub-lithofacies can be identified by this method ,it has been verified by 24 coring wells , the coincidence rate of lithofacies and sub-lithofacies is 84.6% and 77.2% respectively ,and the method is good to identify lithofacies .关键词
