Abstract: The factors affecting the production of coalbed methane well after fracturing are numerous and complex. It mainly includes geological conditions, fracturing factors, drainage and other aspects. This paper mainly discussed the fracturing factors which affect the production after fracturing of coalbed methane well. Through statistics, processing, analysis and summarization of great amount of data in 2009 in Hancheng block, the results have been obtained, showing positive relationship between the pumping off pressure, actual fluid, sand into the well and the effects of coalbed fracturing for seam A#, B#, C#, the inversely proportional relationship between the pressure drop and the effects of coalbed fracturing for seam A#, C#. Therefore, by using the results of this study, the coal bed methane wells after fracturing could achieve the desired output results by adjusting and optimizing construction parameters.
