Jiannan Region of Lower Jurassic Ziliujing group Dongyue Temple argillaceous shale development, I Taguchii in the period of generally see good oil and gas shows. Shale gas reservoir source and reservoir type oil and gas reservoir, which belongs to the shale properties of reservoir, and has low porosity, ultra low permeability characteristics, this article through to the Jiannan structure artesian well group Dongyue Temple period of shale gas reservoir lithology, physical property, electric, gas bearing characteristics and reservoir "four properties" research, combined with core, mud logging, gas test data statistical analysis of shale gas reservoir physical property and electrical limit value, to further establish the effective thickness interpretation chart, draw shale gas quantitative interpretation of standard limit, for shale gas evaluation and interpretation provides reference.
