Hydraulic fracture monitoring for coalbed methane pilot wells located in Xinji Coal Mine

This paper presents an economical and effective mathod of hydraulic fracture monitoring,which applied to the CBM pilot wells located in Xinji Coal Mine,by comparing and analyzing typical monitoring methods,with the sum-up of application of temperature logging and electrometric method in Xinji Coal Mine,that means using the credible temperature logging to measure the fracture height and electrometric method to measure the orientation and length of hgdraulic fracture. It is proved that this method is objective and accurate,provides a referable method for the future in this field or even other field.
