Reservoir heterogeneity is one of the main bottlenecks that affect the exploration and development of shale gas in coal measures. By analyzing the compositional and reservoir characteristics of the shale samples of Taiyuan Formation (Fm.) and Shanxi Fm. in the Ningwu basin, the intervals and types of shale are divided. The macro heterogeneity of TOC, mineral porosity, surface area, pore volume and the micro heterogeneity of pore structure are analyzed to reveal the influencing factors of the macromicro heterogeneity. The result shows that the average thickness of the shale in Taiyuan Fm. and Shanxi Fm. are 32.77 m and 67.68 m respectively, and can be divided in 5 intervals and 4 types of shale. According to the property parameters, the black shale with medium TOC, porosity, water sensitivity and high brittleness is highquality reservoir which is most conducive for exploitation. The micro pores are mainly affected by the clay mineral content, showing a positive correlation, and TOC content is positively correlated with the micropore volume when the clay content is low. The macro heterogeneity of coal measure shale is mainly controlled by sedimentary and tectonic factors, while the micro heterogeneity is influenced by the diagenesis and evolution. The research results can provide a reliable basis for the selection of high quality reservoirs and fracturing process of shale gas in coal measures.
