| 摘 要： | 阿不亥勘查区位于东胜煤田东北部,区内主要含煤岩系为侏罗系中下统延安组,主要含5个煤组,含煤9~22层,平均15层。含煤地层岩性空间上变化频繁,给煤岩层对比研究工作带来很大难度。文章通过选取岩性组合对比法、标志层法、层间距法和测井曲线对比法并结合地震剖面成果,对区内煤层进行综合对比研究,共编号煤层18层。其中,可采煤层15层,不可采煤层3层,可采煤层中基本全区可采煤层3层（4-1、4-2中、6-2中）,大部可采煤层9层（2-2上、2-2中、2-2下、3-1、3-2、4-2上、5-1、6-2上、6-2下）,局部可采煤层3层（2-1、3-2下、6-1）。主要可采煤层（基本全区可采和全区大部可采）对比可靠程度相对较高,煤层结构简单,厚度变化较小,属于较稳定煤层。

| Abstract: | Abuhai Exploration District is located in the northeast of Dongsheng Coalfield.In the study area,the mainly coal measures is Yan'an Formation of Lower-middle Jurassic,which include 5 coal-seam groups,9-22 seams and 15 seams on average.Lithology of coal-bearing strata changes frequently in space and this makes it great difficult in comparative study of coal seams.Through multiple methods of lithological combination,marker beds,interlayer spacing,correlation of logging curve and inversion profile of 2d earthq... |
