【摘要】 祁南勘查区地表条件简单,但是地下目的层埋藏深,且构造相当复杂。由于野外地震勘探受地面村庄和沟渠的影响,未能搜集到可靠的、满意的资料,通过运用真振幅恢复测试、高通滤波、野外静校正、反褶积测试、三维切除处理、高精度速度分析和叠前时间偏移等主要方法反复测试,设定最佳参数,保证了资料的高分辨率、高信噪比及高保真度,获得理想的成果。更多还原

【Abstract】 The surface condition of the Qinan exploration area is simple,however,the destination is buried in deep underground with complex structures.With the influences from the villages and canals on the surface,no reliable results have been obtained through field exploration.By means of the true amplitude recovery testing,high-pass filtering,field statics,deconvolution testing,3D mute processing,high-precision velocity analysis and pre-stack time migration and other major methods,after repeated testing,the information has been ensured with high resolution,high signal to noise ratio and high fidelity,and reliable results have been obtained.更多还原
