利用地震偏移剖面解释岩浆岩的方法分析
|
摘要
在吉林敦化黑石煤炭资源赋存区,岩浆岩发育,煤层较大范围内受到岩浆岩侵蚀,岩浆岩侵蚀部位在地震剖面上差异十分明显,利用二维地震方法,对水平和偏移时间剖面特征进行分析和解释,就可确定其分布范围及位置。
The area of Heishi in Dunhua,Jilin Province,the magmatic rocks develop in the host coal rocks,coal seam were eroded by a larger erosion of magmatic rocks,the eroded parts of magmatic rocks is very obvious difference in the seismic section by two-dimensional seismic method,Through the analysis and interpretation of stacked section and migration time section characteristic,we can availably determine position of occurrence and space distributive scope.
