【摘要】 陷落柱赋存特点及其与围岩地层的物性差异,决定了其陷落柱特殊的地震响应特征:如地震剖面出现同相轴的中断、扭曲、弯曲、倾斜现象以及振幅、波形、频率等动力学特征突变现象,另外还可见异常波;在属性切片上其形态特征表现为椭圆形、似圆形,有时可见到长条形或串珠状。断陷点的解释是陷落柱解释的关键,为此利用放射状、网格状测线切出的剖面来解释陷落柱,能够基本控制断陷点的位置,再配合属性切片、三维可视化显示等解释手段,全方位、多角度地对数据体进行分析,大大提高了解释陷落柱的准确度。运用该种方法解释的成果已得到实际资料的验证。更多还原

【Abstract】 The hosting features and physical property differences with surrounding rock of subsided columns decide their special seismic response characteristics. Such as phenomena of breaking lineups,twisting,bending and tilting on seismic sections,as well as amplitude,waveform,frequency kinetic feature mutations,besides,abnormal events;shape characteristics on attribute slice have ellipse,circle-like,sometimes long strip or beaded. The interpretation of breaking point is the key of subsided column interpretation,for this,sections derived from radial,latticed traverses are used in interpretation,thus can basically control the locations of breaking points. Then combined with means of attribute slice,3D visualization,carry out omnidirectional,multi-angled data volume analyses,thus can improve accuracy of subsided column interpretation greatly. The method is already verified in practices.更多还原
