山西省沁水煤田固县井田主要可采煤层及煤质特征分析

摘要

以大量钻孔成果数据为基础,通过钻探取芯、数字测井等手段对井田范围内主要可采的3号、15号煤层在横向平面上的厚度变化规律进行了分析研究,并利用煤质化验数据及测井曲线相对比的方式对15号煤层在垂向上的煤质特征变化规律进行了研究,结果表明:3号煤层全区稳定可采,为低灰、特低硫、高发热量之无烟煤,15号煤层全区稳定可采,为低灰、高硫、高发热量之无烟煤.%On the basis of a lot of achievements in research and drilling data,by coring drilling,by means of three digital logging,the thickness of 15 # coal seam in horizontal plane change regularity was analyzed,and use of coal quality analysis data and well logging curve comparison results of 15 # coal seam in vertical variety patterns of coal quality characteristics are analyzed.The result shows: 3 # coal seam in the stable recoverable,as low ash,low sulfur,high calorific value of anthracite coal,15 # coal seam in the stable recoverable,low ash,high sulfur,high calorific value of anthracite coal.
