Coalbed Methane Reservoir Characteristics and Mining Technology in Xinjiang Fukang Baiyanghe Mining Area

The detailed comparative anatomy technology is used to analyze the surface structural fissure mapping and underground coal reservoir in Fukang Baiyanghe Mining Area of Xinjiang. Combined with coal reservoir observation sampling, test analysis, drilling and logging data, the characteristics are studied, including coal reservoir space distribution, rock physics, gas content, adsorption characteristics, reservoir pressure, big fracture system, closed characteristics of CMB reservoir. The results show that 44^#, 43^#, 42^#, 41^# and 39^# coal reservoirs are fit for coalbed methane exploration; for CBM reservoir characteristics in this area, the countermeasures are proposed, such as well type selection, drilling well and drainage.
