Abstract: To obtain the relationship between the characteristics of coal reservoirs and logging data, starting from regional geological background, through analysing the characteristics of coal core, well logging, mud logging, seismic data, the structure of coal seam of FanzhuangZhengzhuang in Qinshui Basin and five characteristics of high-rank coal reservoir were studied, s uch as lithology, physical properties, gasbearing properties, aquosity, gassing property. Results show that in the plane the evolution of the planar coal seam structure of Fanzhuang-Zhengzhua ng has strong regularity, the number of dirt band in the south of Fanzhuang is least, 1 ~ 2 in general, the second is Zhengzhuang, 2 ~4, the number of dirt band in the north central of Fanzhua ng is most3 ~ 6. The average ash content of coal reservoir is 11% in Fanzhuang Block, and the average ash content of coal reservoir is 18% in Zhengzhuang Block. The average porosity of C oal reservoir is 9% in Fanzhuang Block, and the average porosity of coal reservoir is 5% in Zhengzhuang Block. The higher the coal quality parameters is, the greater the single well productio n capacity is.The coal quality parameters in the south-west and middle section of Fanzhuang is best. The coal quality parameters of Zhengzhuang are worse than those of Fanzhuang, and this conclusion was also validated in the field production.
