Evaluation on development potential of deep coalbed methane in middle-east area of Qinshui Coalfield

SU Yufei;ZHANG Qinghui;QU Xiaorong;Shanxi Research Institute of Coal Geological Survey;  
In order to promote a further development of the deep coalbed methane industry in Shanxi Province,based on the analysis on the development status of the coalbed methane resources survey in Shanxi Province,an analysis study was conducted on the structure of YusheWuxiang area,basic characteristics of the seam,coalbed methane content and physical characteristics of the reservoirs in the middle-east part area of Qinshui Coalfield and the study held that in the study area,the structure was stable and the development potential of the deep coalbed methane was tremendous. The study results showed that the gas content of No. 3 seam and No. 15 seam in the study area was 18.63 m~3/t and 17.58 m~3/t individually in average value. With the estimations,the potential resources volume of the coalbed methane in No. 3 seam and No. 15 seam of the study area was about 2 278 × 10~8 m~3. Meanwhile,with the summarization and evaluation of the coal measure "three gases"co-exploration technology,the open-hole multi-parameter logging and the gas logging with the drilling was found as the important survey means to discover and evaluate the coal measure shale gas and other unconventional natural gas. According to the available geological information and the knowledge obtained,the further survey orientation and the study focus of the area were provided.
