【摘要】 通过分析钻孔资料,首先对煤层进行了精细分层,然后利用三维地震反演技术将地震数据、地质构造模型、井点测井资料有机地结合,研究了各煤层三维空间展布及其顶底板岩性特征,理清了煤系地层的沉积演化特征及目标层系构造演化与断裂发育特征,并对测区的煤层分层方案进行了调整,将全区原划定的4个煤层(B1、B2、B3、B4)调整为5个煤层(B0、B1、B2、B3、B4)。更多还原

【Abstract】 Through drilling data analysis,carried out coal seam precise layering,then using 3D seismic inversion,judiciously combined seismic data,geological structure model and well logging data,studied 3D spatial extending features and their roof,floor lithologic characteristics.Clarifying coal measures strata sedimentary evolution,target series of strata and faulting development features,then adjusted coal seam layering scheme,has changed original 4 coal seams(B1,B2,B3 and B4) into 5 coal seams(B0,B1,B2,B3 and B4) in the area.更多还原
