| 摘 要： | 西山窑组上段是卡姆斯特煤田主要含煤地层。通过对大量钻孔、地球物理测井资料的分析,应用层序地层学基本理论和方法,对卡姆斯特煤田西山窑组进行层序地层分析,识别出SQ4相当于西山窑组上段。通过分析沉积基础图件,明确了本区西山窑组上段沉积演化特征。高位体系域煤层通常较低位体系域及湖侵体系域煤层分布广泛且稳定。通过对卡姆斯特煤田西山窑组上段的沉积演化特征和聚煤规律的分析,为下一步煤炭地质勘查提供了依据。

| Abstract: | The upper member of Xishanyao Formation is the main coal-bearing stratum in Kamst coalfield. Based on the drilling and logging data, and by the means of the principle and method of sequence stratigraphy, this paper studied the sequence stratigraphy of Xishanyao formation in Kamst coalfield. The sequence of SQ4 is equivalent to the upper member of Xishanyao Formation. The characteristics of sedimentary evolution of the upper member of Xishanyao Formation were also defined through the study on sedimentation basic maps. The coal seam of highstand system tract was more widely distributed and more stable than that of lowstand system tract and transgressive system tract. The result provided the basis for further exploration of coal geology in Xishanyao Formation in Kamst coalfield. |
