摘要
大佛寺井田位于鄂尔多斯盆地东缘,煤层气资源量约31.70亿m^3,资源丰度平均0.41亿m^3/km^2,局部可达0.70亿m^3/km^2以上,具有巨大的开发利用价值,同时也是彬长矿区最具开发潜力的区域。本文分析并总结了大佛寺井田地层、水文地质、区域构造、煤储层特征、含气性特征及煤层气勘探开发现状,指出了存在的问题并提出了新的开发思路,对下一步煤层气开发具有一定的借鉴作用。
Dafosi Coal Field is located in the eastern edge of the Ordos Basin, and the CBM resources of Dafosi Coal Field reaches about 3.17 billion m3, with the average resource abundance of 41 million m3/ km2 and locally reaching over 70 million m3/km2, which shows a great value for CBM development and utilization. This area is also the region with the highest development potential in Binchang Mining Area. This paper analyzes and summarizes the current situation of coal field formation, hydrogeology, regional structure, coal reservoir characteristics, gas-bearing characteristics and CBM exploration and develop- ment, points out the existing problems and puts forward the new development ideas, which is an impor- tant reference for CBM development in the next step.
