| Abstract: | Based on experiences of previous treatment data of coalbed gas test wells,the featrues of fracture treating pressure in coal seams and the relationship between the depth,R o and fracture pressure gradient are analyzed.The fracture features after fracturing operation are also classified and summarized,according to fracture orientation and height recorded by fracture monitoring(temperature logging,ground potential and uphole survey).Based on that some useful suggestion and valuable reference for the future fracturing in coalbed gas wells are provided. |

| Keywords: | coalbed gas fracture treating pressure fracture orientation fracture height |
