【摘要】 在我国南方山地地区,表层条件复杂多变,地形起伏剧烈。表层基岩直接出露,地下地层的低、降速带厚度、岩性和速度的横向变化剧烈,导致地震记录中静校正问题严重,信噪比较低。本文针对复杂地区地震资料的特点,对记录中的干扰波、地表和深层地质条件进行了分析,认识各种干扰波的特征与地表条件的关系,采取相应的措施对地震数据进行静校正处理,在实际的处理中取得了良好的效果,并对其处理效果进行了分析。更多还原

【Abstract】 In the mountainous regions of the south of China,due to the complicated condition of the earth surface and the drastic topographic relief,the directly exposed bedrock,the low underground stratum and the other changes lead to the static correction problem during seismic recording and the low SNR problem.This paper,aiming at the characteristics of the complex regional seismic data,analyzes the interference wave,earth surface and deep geological structure during seismic recording.Their relationships between the characteristics of the interference waves and the surface conditions are distinguished.The appropriate static correction method is used to correct the seismic data,the good effect is gained in the practical process,and the treatment effect is analyzed.更多还原
