摘要
本文应用测井相解释技术对聊城煤矿区山西组的沉积环境进行了研究,认为该区山西组为三角洲沉积体系.作者在分析了山西组主采煤层(M_3)成煤作用的基础上,进而运用灰色系统理论,建立了 M_3的灰色数字模型,并对煤厚变化进行了灰色预测,为煤炭资源的评价与开发提供了必要的理论依据。
The sedimentary environment of Shanxi Group in the Liao City coal field is studied by writers using explanation technique of well-logging facies in this paper.Shanxi Group in this distract is known as daltaic deposit systems. After analysing formation coal affect of mainly workable coal seam(the third coal seam) in sbanxi Group,writers have established grey mathematical models of the third coal seam ap- plying theory of grey system to the third coal seam,and forecasted change of thickness of the coal seam.
