前陆冲断带深度剖面的建立及三维可视化研究——以酒泉盆地南缘金佛寺冲断带为例
|
摘要
金佛寺冲断带因无法直接获取花岗岩体速度数据,且岩体本身属地震波高反射介质,导致岩体下伏深部构造在时间域与深度域地震剖面影像的形态产生较大的偏差。本文利用已获取的模拟花岗岩体地下深部温压条件下波速与深度的实验室测试数据,定量化花岗岩体地下深度与波速的关系,进行金佛寺冲断带二维地震剖面的时深转换,并进行深度域剖面与时间域剖面之间掩伏构造形态的分析比较。在此基础上利用gocad软件对冲断带构造进行三维可视化建模,并讨论其深部构造特征,认为下伏中新生界整体为南西倾单斜,局部发育掩伏构造,掩伏构造高点埋深较大,两翼倾角减小。
Jinfosi Pluton is seismically highly reflective medium and it has been difficult to obtain velocity data of the pluton directly.The deep structures of Jinfosi thrust belt revealed by time-domain and depth-domain seismic data show significant difference.We used the velocity data that were derived in laboratory under high temperatures and pressures simulating conditions at depth to quautify the relationship between velocity and depth underground.This allows time-depth conversion for the 2-D seismic data of the Jinfosi pluton and comparison of the deep structures of Jinfosi thrust belt revealed by the time-domain and depth-domain seismic data.Based on the new depth data and interpretation,GOCAD software was employed to establish a 3-D geological model,which allowed further discussion of the deep structures.The model shows that the Mesozoic-Cenozoic rocks form a deeply buried monocline which dips SW and structural highs are relatively deeply buried with dips diminishing toward the two limbs.
