摘要：

六盘水亦资孔盆地上二叠统煤系可采煤层厚度20～40m,煤层含气量为10～20m3/t,煤阶主要为肥、焦、瘦煤,利于煤岩割理发育。煤体结构为块状、碎块状,煤层渗透率相对较高。煤层气资源量为35878×108m3,平均资源丰度429×108m3/km2,具有良好的煤层气勘探开发前景。经钻井评价,金竹坪区块为较有利区块,有继续勘探开发潜力;亮山区块为较差区块,不具备开发价值。

Abstract:

The Permian coal measures in Yizikong basin in Liupanshui area have workable seams of 20- 40 m thick with gas content of 10- 20 m2/t. Coals are mainly of rich coal, coking coal and lean coal, which are favorable for development of cleat. Coals are in massive or lumpy texture. Permeability of coalbed is relatively high. The basin has coalbed methane resources of 358.78 billion m3 with an average abundance of 429 million m3/km2. Therefore, prospects for exploration and development of coalbed methane in the basin are bright. Evaluation through drilling several wells in the basin shows that Jinzhuping block is a favorable area with further exploration and development potential, while Liangshan block is a poor area without any development value.

Key words: coalbed methane, gas content, exploration and development, gas production rate, water production rate
