Abstract
The authors evaluate the influence exerted by tectonic structure on methane content patterns in QD site in the Qinshui Coal Basin. The gas flow rate versus bottomhole-fault distance and the minimum bottomhole-fault distances for profitable methane production are determined. The obtained results are applicable to methane well patter design in the test site.
