| 摘 要： | 运用层序地层学原理和方法,利用钻探和测井资料以及煤的显微组分和煤相参数分析,对新疆准东煤田西山窑组的层序单元进行了划分,特别对煤层中的准层序进行了确定。研究结果表明:西山窑组为1个三级层序,并由低位、湖扩和高位体系域构成;在煤层中确定了水进型、水退型2种准层序类型以及缓慢水进型准层序组和相对快速水进型准层序组;湖扩体系域由水进型和水退型煤层构成,高位体系域由水退型煤层构成;煤层煤相总体为干燥森林沼泽。

| Abstract: | On the basis of the principles and approaches of sequence stratigraphy,using drilling and logging data,maceral and coal facies parameters of coal seam,this study divided the sequence units of Xishanyao Formation in Zhundong coal field,especially the parasequences in coal seams.The results showed that Xishanyao Formation belongs to one third-order sequence and consists of low-stand system tract,transgression system tract,high-stand system tract;the transgression parasequence and regression parasequence,and t... |
