摘要
结合测井、钻探和地质成果,充分利用二维/三维地震勘探技术,以利用测井资料制作合成地震记录和地震正反演为手段,以标定标准波和煤层反射波的波形特征与煤层宏观结构关系为重点,解释了煤层一次、二次分叉分界线和煤层视分叉点平面位置,圈定了煤层赋存范围及煤层宏观结构,查明了厚度变化趋势。
Combined with logging,drilling and geological results,making full use of 2D/3D seismic exploration technology,making synthetic seismic records and seismic forward and inversion by using logging data,focusing on calibrating the relationship between the waveform characteristics of standard wave and coal seam reflected wave and the macrostructure of coal seam,the primary and secondary bifurcation boundaries of coal seam and the plane position of apparent bifurcation point of coal seam are explained,and the occurrence range and macrostructure of coal seam are delineated.The changing trend of thickness is found out.
