| 中文摘要: |
| 主要是从霍林河河组的地质条件及其煤层特征双角度出发,详细地阐述了霍林河盆地煤层气的基本地质特征,指出煤的镜质组反射率多在0.5%~0.6%之间,煤质含气量最高为7.7m3?t-1。煤质中煤层气含量以及煤层气中甲烷含量随深度加大而迅速增加。400m以下为甲烷带,400m以上为甲烷——氮气带。同时,预测了有利于煤层气形成和勘探的有利地段,9-73孔、21-11孔附近地区为最有利煤层气勘探区。 |
| 英文摘要: |
| The geological characteristics of coal-bed gas in Huolin Basin are described in detail from the geological conditions of Huolin river and features of the coal bed. The reflectivity of coal-seam mirror-quality body in this area is in general between 0.5% and 0.6 %. The maximum content of coal-bed methane reaches 7.7 m3?t-1. With increasing depth of coal buried, contents of the coal-bed gas and methane in it increase rapidly. More than 400 meters below ground is the methane zone, and the region above 400 meters depth is the methane-nitrogen zone. In addition, favorable locations for coal-bed gas formation and exploration are predicted, and areas nearby 21-11 and 9-73 holes are most favorable for exploration. |
