复杂山地地震资料采集参数论证和观测系统的设计—以西昌盆地昭觉区块的地震资料采集为例
PARAMETER AUGMENTATION FOR SEISMIC-DATA ACQUISITION IN COMPLEX MOUNTAINOUS TERRAIN AND ITS GEOMETRY DESIGN:AN EXAMPLE FROM ZHAOJUE BLOCK,XICHANG BASIN
【摘要】 地震数据采集观测系统的优化设计是整个采集工程设计的重要环节,针对西昌盆地地形起伏变化大、地表和地下地震地质条件都较复杂的特点,解剖分析了1994年及2004年的施工参数,并对以往采集的单炮记录和叠加剖面进行对比分析,优化得到该地区的地震施工参数,圆满完成了1354km二维地震资料的采集。
【Abstract】 An optimization design of seismic-data acquisition geometry is important for entire acquisition engineering.According to characteristics of large topographic relief,and complex seismic and geologic conditions in surface and subsurface of Xichang Basin,the operation parameters from 1994 and 2004 are thoroughly analyzed.The single shot records and stack sections acquired in the past are also comparatively analyzed,and the optimized parameters are obtained,2D seismic data with 1354 km long is satisfactorily acquired.
