Abstract: In order to evaluate the exploration and development potential of the black shale of Dalong Formation in Jianshi area,western Hubei,the reservoir characteristics and organic geochemical characteristics of shales in the study area were analyzed by means of FE-SEM,XRD,low temperature N2 adsorption isotherms and CH 4 adsorption isothermal experiment. The results show that the shale reservoir spaces are dominated by mineral dissolved pores and organic pores,and quartz is the major brittle mineral in shale,which has reached mediumhigh level. The shale is classified as ultra-low porosity and ultra-low permeability reservoir with a rock porosity of 0.65%-2.79% and a permeability of 0.000 8-0.462 1 mD. The TOC content ranges from 1.62% to 13.60%,indicating its high organic material content and good material basis for shale gas. The kerogen type is mainly Ⅱ,and the Ro has reached later over-mature stage. The gas content of shale samples is 0.741-3.703 m3/t,with an average of 2.714 m3/t. The adsorbing gas content appears a positive correlation with TOC content and porosity,and shows week correlation with quartz content and organic maturity. The shale of Dalong Formation in Jianshi area deserves to be exploited due to its good hydrocarbon potential and reservoir conditions.

Key words: shale, reservoir characteristics, organic geochemistry, gas-bearing property, Dalong Formation
