【摘要】 采用地质定性—地球物理定量相结合的方法,利用地震资料多属性解释及属性分析理论,系统研究了无煤带地震属性响应特征,分析了无煤带与地震信息之间的关系,对比研究了无煤带瞬时属性在偏移和相对波阻抗数据体上的差异及相关关系,并在此基础上综合利用方差属性对小康井田南二采区进行了实验研究,确定了勘探区无煤带的发育范围,实现了应用地震属性预测未采区无煤带的目的。更多还原

【Abstract】 To use combined geological qualitative-geophysical quantitative method and seismic data multi-attribute interpretation and attribute analysis theory,have systematically studied seismic attribute response features of coal barren zone,analyzed relations between coal barren zone and seismic information,comparatively studied coal barren zone instantaneous attribute difference and correlativity on migration and relative wave impedance data volume.On these bases,we used variance attribute comprehensively,carried out experimental research on South No.2 winning district of Xiaokang minefield,determined coal barren zone extent in the exploration area,realized target of to predict coal barren zone in yet to be mined area through seismic attribute.更多还原
