摘要
为了研究黔西织纳煤田戴家田井田的含气特征及控气地质因素,依据大量的煤田地质勘探资料及实验室测试分析数据,探讨了研究区控气地质因素对煤层气含气量的影响作用。研究结果表明:在诸多地质影响因素中,地质构造,水文地质,煤层埋深及灰分含量是控气的主要影响因素,含气量与煤层埋深呈正相关关系,而与灰分含量成负相关。
In order to study the gas content features and the gas control geological factors of Daijiatian Minefield in Qianxi Zhixi Coalfield, according to the great coalfield geological exploration information and the lab measurement and analysis data, the paper had a study on the gas control geological factors of the study zone affected to the coal bed methane content. The study results showed that in the several geological influence factors, the geological structure, hydrology; seam depth and ash content would be the main influence factors. There was a positive related relationship between the gas content and seam depth and there was a negative related relationship between the gas content and the ash content.
