煤矿采区三维地震资料解释中的切片技术及其应用

长期以来,煤矿采区三维地震勘探资料解释的工作流程与二维地震勘探基本相同,三维地震资料相对二维地震资料所具有的许多解释方面的优越性未能有效发挥出来,人机联作的过程相对简单.在三维地震勘探获取的三维数据体基础上,可做进一步的运算和分析,提取速度、振幅、频率、相位等相关信息,并利用等时切片、层拉平切片、断层切片、面块切片、方差体、相干体等各种技术,有效解释小构造、小褶曲及岩性方面的信息.

Slicing Technique and Its Application in Coalmine District 3D Seismic Data Interpretation

Over a long period of time,the data interpretation work flow of coalmine district 3D and 2D seismic prospecting are basically the same.Many interpretation superiorities of 3D seismic data over 2D seismic data cannot be brought into play effectively;man-computer interaction process is relatively too simple.Based on 3D data volume acquired from 3D seismic prospecting,may have further operation and analyses,to collect relevant information of velocity,amplitude,frequency and phase,to use techniques of time slice,datumized slice,tomographic slice,surface slice,variance cube,coherent cube etc.to interpret minor fault and fold and lithologic characters.
