Abstract: In order to accurately study reservoir characteristics and well logging evaluation method of shale gas, the paper analyzes the basic features of shale gas reservoirs in detail based on investigation of a number of literatures at home and abroad and in combination with geological data and logging data. These basic features include sedimentary environments, mineral composition, organic matter, physical properties, reservoir feature etc. At last, it puts forward the way of shale gas logging evaluation from identification of shale gas, evaluation of hydrocarbon generating potential, and evaluation of reservoir parameter. This summary of the reservoir characteristics and well logging evaluation method will be helpful for research on exploration and development of shale gas.
