西黑山矿区西山窑组下段含煤岩系层序地层格架研究
|
摘要
以含煤层序地层学和高精度层序地层学的理论和技术方法为指导,通过钻井岩芯实际资料研究,较为详细的识别了西黑山矿区西山窑组下段煤层。本文研究重点是含煤层段西山窑组二级、三级层序的划分,主要依据钻井、编制分析单井相图,以准噶尔盆地含煤层序地层学和沉积学为基础,通过对钻孔资料,相关剖面的分析,并结合前人研究分析,识别出准噶尔盆地东部研究区中侏罗统层序地层界面类型,从而建立其层序地层格架,对今后该地区找煤并开发具有一定指导意义。
This paper focused on the division of seam segment sequences of Xishanyao group. Based on the Junggar Basin coal seam sequence stratigraphy and sedimentology, and the analysis on the materials of drill hole and relevant cross-sectional, we identified the stratum interface type in the eastern area of Junggar Basin in Jurassic sequence stratigraphy. Meanwhile, it can help establish the sequence stratigraphic framework to guide the prospecting and the future development in this area.
