Abstract
Previously, the study of the coal reservoir characteristics in China has been focused on the shallow coal seam (<1500 m), but less attention has been paid to the deep coal reservoir (>1500 m). Thus, the exploration and development of CBM resources is hindered. This paper aims to investigate the deep CBM at 1755m-1764m in the second member of the upper Paleozoic Shanxi Formation and that at 1815m-1833m in the second member of the upper Paleozoic Taiyuan Formation with the gas content and other parameters from wireline coring in Well Gu 1.The results show that the Shenmu area has the low-medium rank coal with the high vitrinite content and the medium-high gas-bearing potential. This study provides insight into the gas content of the coal seam deeper than 1500m and establishes a basis for evaluating the 1500m-2000m deep CBM resources within the Ordos Basin. Keywords—deep coalbed methane; coal reservoir characteristics; coal seam gas bearing potential; Ordos Basin
