本文以南方碳酸盐岩地区某复杂构造工区为例,讨论了超多道地震资料处理中应注意的几个问题。分析了在单检波器、小道距、小偏移距和长排列接收条件下干扰波的效应以及用超多道处理方法解决的途径。

Taking the case of a carbonate area where structure is complex as an example, the paper deals with some problems warrant attention while processing the seismic data wilh larger number recording channels. The effect of inteference wave (receiving conditions; single geophone, shorter group interval and offset, and longer spread) is examined. Also, the approaches aimed at solving the long -standing problen arisen therefrom by way of the larger multi -channel seismic data processing are remarked.
