贵州西部煤层气资源丰富,总资源量50 226×108m3,其中埋深200～1 500 m范围的资源量为25197.4×108m3,资源丰度平均为1.42×108m3/km2;其中又以六盘水地区煤层气地质条件较为优越,表现为煤层厚度大,可采煤层分布稳定;煤种齐全,煤岩含气量5～35 m3/t,对比六盘水地区诸盆地的煤层气地质条件,认为亦资孔盆地、岩脚盆地、格木底盆地最有利,其余盆地次之.亦资孔盆地应作为首选勘探盆地,金竹坪区块应作为贵州西部煤层气钻井试验评价示范区.

Exploration Prospects for Coal-bed Gas Resource in West Guizhou

The coal-bed gas resource is very rich in West Guizhou. Its total source reserves of 5.0226 billion m , among which there are 2. 51974 billion m3 discovered underneath the surface with 200 ~ 1500 meters deep. The average resource abundance is 1.42 million m3 per 1 km2. Coal-formed gas geo logical conditions in Liupanshui area are comparably advanta geous , which can be shown by many points like the high thick ness of coal-bed. The distribution of recoverable coal reservoir is stable. There are all kinds of coal. Gas-bearing reserve of coal rock is 5 ~ 35 m3 per one ton. It is thought that Yizhikong Basin, Yanjiao Basin and Gemudi Basin were better than the other basins. Yizhiking Basin should be regarded as the first basin to be explored. The Jingzhuping Block should be acted as a model experimental and assessmental area for coal-bed gas drilling in West Guizhou.
