| 摘 要： | 济宁二号煤矿3煤分叉为3上、3下煤层后,在地震剖面上表现为复杂的"薄互层"反射特征,这在常规地震时间剖面上确定"视分叉点"的精度不高。采用小波分析技术,改善了原始三维地震成果数据体的信噪比和分辨率,使得3煤层宏观结构解释的精度得到显著提高。

| Abstract: | The Coal Seam No.3 of Jining No.2 Mine shows on seismic section "thin interbedded" properties due to its branching into Coal Seam No.3 upper and Coal Seam No.3 lower,which caused the accuracy of determing apparent branch point on conventional seismic time section.The application of wavelet analysis technique improved the signal to noise ratio and resolution of original 3D seismic result data body,therefore,the accuraccy of macro-structure explanation of Coal Seam No.3 is apparantly increased. |
