“八五”期间,三分量地震资料采集和处理为国家重点攻关课题之一,我们在东北某气田首次用炸药震源激发,斜三分量检波器接收,得到斜三分量地震记录,使人们在这方面的研究工作从理论进入实际应用。本文将介绍我们在斜三分量地震资料常规处理方面的一些思路和经验,包括一些处理参数的选取方法、一些中间处理结果的分析和处理流程等,望引起大家的兴趣和探讨,以推动此项研究工作的进展。

During the eighth five-year plan,as one of country,s major key projects,in a gas field in northeastChina, we first time collect our oblique tricomponent seismic recordings by use ofcompressional point source explosion and oblique tricomponent geophone receiving,so that we cancarry out our study work to real data,not only to theoretic data. This paper will introduce some ofour idea and experience about the processing of oblique tricomponent real data, including thechoosing method of some processing parameters, the analysis of some intermediate results,flowchart of processing,and so on,in order that readers can take it as a reference and make theirdiscussion.
