摘　　要：为了精确预测袁大滩井田首采区5煤层厚度变化及薄煤带范围,采用地震、测井和地质多学科结合的思路,综合采用常规时间剖面、属性分析、波阻抗反演三种方法,圈定了5煤层薄煤带面积为0.68 km^2,取得了预期效果。In order to predict accurately the thickness change of 5th coal seam and the range of the thin coal zone in the first mining district of Yuandatan mine,the idea combining seismic exploration,well logging and geology was adopted.The conventional time profile,attribute analysis and wave impedance inversion were used.It was located that the area of the thin coal zone was 0.68 km2,achieving the expected effect.

关 键 词：三维地震 综合解释 地震属性 波阻抗反演 薄煤带
