内蒙五间房煤田主要含煤段煤层综合对比
|
摘要
五间房煤田为二连盆地群东段的一个含煤盆地,盆地内主要发育有白垩系巴彦花组的7个煤组。搞好煤层对比,对研究二连盆地群煤系地层具有重要意义。根据五间房煤田东南部含煤地层特征,采用综合对比方法,利用标志层法、煤层间距法、煤组(层)结构法、测井曲线法和地震波阻追索法进行综合煤层对比,取得了比较好的对比效果。
Many basins of Erlian Basin Group are connecting to each other,Wujianfang coalfield is a coal-bearing basin located in the east of Erlian Basin Group.There are mainly seven coal groups of Cretaceous Bayanhua formation inside the basin.Making seam comparison is significant for researching coal-bearing stratum of Erlian Basin Group.Based on the characteristics of coal-bearing stratum in the southeast of Wujianfang coalfield,the paper has introduced a way of combining key horizon method,seam interval method,seam structural method,well log method with seismic wave trace method to make seam comparison,which achieves good comparison efficiency.
