黔西南中营向斜煤层气储层综合评价

Comprehensive Assessment of Coal Bed Gas Reservoir in the Zhongying Syncline, Southwest Guizhou

综合分析了黔西南地区中营向斜煤层的分布、厚度、埋深煤质、含气性等方面特征,该区主要含煤地层为二叠系龙潭组,含煤40余层,可采15层。煤储层含气量较高,煤层气的保存条件较好,估算区内埋深500~1 500m深度范围内煤层气资源量为93.09亿方,该区煤层气资源具有良好的开发前景。

This paper deals with the occurrence of CBM in the Zhongying syncline, southwest Guizhou, including burial depth and thickness of coal layer, features of coal and gas content. The coal-bearing formation is the Permian Longtan Formation with 40 coal beds and 15 minable seams. The preserved conditions of CBM are advantage. The CBM resources in the depth from 500 to 1500 m in this area are estimated at 93.09×108m3.
