摘要
四川盆地边缘复杂山区地形起伏剧烈,相对高差大,灰岩普遍,地表地震测量条件复杂,能量吸收衰减明显,低频现象严重,导致地震记录中静校正问题严重,信噪比较低。针对该地区的特点,利用高程静校正和层析反演静校正进行监控处理,解决静校正问题,便于及时指导野外施工,保证地震数据的采集质量。
Large elevation difference and wide distribution of limestone in the marginal mountains of the Sichuan basin result in obvious energy attenuation, serious low frequency phenomenon, low signal noise ratio and serious static correction problems of seismic records. Elevation static correction and tomographic inversion static correction may be used for solving above-mentioned problems.
