摘要

在以往柴达木盆地地震勘探中,为了达到压制噪声的目的,常常是用大组合接收。但是随着勘探的深入,大组合的劣势逐渐显现。单检波器接收, 在数据后期处理过程中进行道组合,既能达到压制干扰的目的,又能消除大组合时道内静校正影响,有利于数据的分辨率、保真度和成像精度。本文结合盆地内尖顶山地区某条测线的数据进行了道组合处理、分析,探讨了在处理中进行道组合,完成野外检波器组合的功能的方法、流程以及应注意的问题,展示了道组合处理的效果。

Abstract：

In the past seismic exploration in Qaidam Basin,large combination receiving has been often used in order to achieve the purpose of suppressing noise.However,as the exploration goes deeper,the disadvantages of the big combination gradually emerge.The single detector receiver can combine the channels in the post-processing of the data,which can not only suppress the interference but also eliminate the influence of statics in the large combinations,which is beneficial to the resolution, fidelity and imaging accuracy of the data.Based on the data of a survey line in the area of the peak mountain in the basin,this paper deals with and analyzes the trace combination,discusses the method,process and problems that should be paid attention to in the process of the trace combination,completes the function of the field detector combination,and shows the effect of the trace combination treatment.

Key words： single point reception path combination processing processing flow
