Abstract: 金海洋矿区为朔州原有小煤矿资源整合后的矿区,为了解决多个采区煤层编号不统一,煤层对比不严谨的问题,从研究区域沉积环境及矿区含煤地层的岩性特征、微量元素特征等入手,绘制矿区岩相古地理图,划分矿区沉积旋回,并以此为基准,运用岩性标志、物性参数、测井曲线特征等方法有效划分各煤层,并进行追踪对比。研究认为,该区太原组主要分3个沉积旋回:第1旋回为太原组底部潮坪相,沉积了稳定的11号煤,11号煤呈西厚东薄、北厚南薄的趋势;第2旋回属于泻湖潮坪相,沉积了全区稳定的9号煤,在区内物源方向及海侵海退方向影响下,9号煤层呈西薄东厚的NE向展布;第3旋回为太原组顶部的河控浅水三角洲平原(水下)相,多次沉积薄厚不均的煤层。
