Abstract
Abstract The rich coal-bed methane resources in the Turpan-Hami Basin are mainly located in the Shisanjianfang, Hami, Shanshan, Sha'erhu, Kekeya, Kerjian, Aidinghu inclines and the Dananhu coal-bed methane reservoirs. The bigger coal-bed reservoirs are sitting at a depth of less than 1500 m. The coalbed methane generation, storage and confining conditions of the Turpan-Hami basin can be indicated by eight key parameters. They are coal-bed thickness, coal rank, missing period, permeability, Langmuir volume, rock covering ability, structural confinement and hydrodynamic sealing environment. These parameters constitute a comprehensive appraisal index system of the coal-bed methane reservoir characteristics of the Turpan-Hami basin. In these parameters, the missing period of coal-bed methane is indicated by a stratum missing intensity factor. It reflects the relative exposure period of coal series. The results of a fuzzy comprehensive judgment showed that the Shisanjianfang coal-bed methane reservoir has the best prospects for exploitation and the Sha'erhu, Shanshan, Hami coal-bed methane reservoirs are next in line.
