吐哈盆地沙尔湖煤田瓦斯赋存规律及影响因素

Gas Distributed Rule and Control Factors of Shaerhu Coalfield in Tuha Basin,Xinjiang

据煤田地质勘查资料和油田钻井资料,对新疆吐哈盆地沙尔湖煤田瓦斯赋存规律进行分析,认为张性断层、贫水区无封闭作用、煤变质程度低等因素是导致沙尔湖煤田瓦斯含量低的主要原因,同时指出随着埋深的增加瓦斯会相应增加,这是今后煤田勘探开发值得注意的问题。

According to the geological exploration of coal and oil field drilling data,gas distributed rule of Shaerhu Coalfield in Tuha Basin is discussed.The results indicated that Leading to the main reason for the low gas content is tensile fault,the water-deficient areas without closed, low coal rank.Also pointed out that with the increasing of depth,the gas will increases,which is worth to noticing in the coalfield＇s exploration and development in future.
