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。
In the mountainous areas of southern China, the surface conditions are complex and changeable, and the terrain fluctuates drastically. The surface bedrock is directly exposed, and the horizontal and vertical changes of the thickness, lithosphere and velocity of the low and slow velocities in the underground strata are drastic, leading to serious static correction and low signal-to-noise ratio in the seismic records. In this paper, according to the characteristics of seismic data in complex areas, the interference waves, surface and deep geological conditions in the records are analyzed, the relationship between the characteristics of various interference waves and surface conditions is recognized, and the corresponding measures are taken to deal with the static data of seismic data. In the actual treatment has achieved good results, and its treatment effect were analyzed.
