三维叠后地震数据可纵向显示的处理方法
|
摘要
在三维地震资料处理中,为使叠后相邻测线的地震数据在绘图纸上能够纵向同时显示,达到节约绘图纸、降低成本的目的,本文提出了一种利用地震资料处理模块生成可纵向显示的三维地震绘图数据的处理方法.该方法通过进行叠后三维数据体的分离、延长测线数据的记录长度、修改线号和数据体合并等处理工作,产生可纵向显示的绘图数据体.经实际绘图显示,不同测线的地震剖面由原来的横向单张显示,转为了纵向的多张绘图.因此,大大节约了纸张,降低了地震资料处理的成本.
In the three-dimension seismic data processing,displaying the post-stack seismic data of adjacent lines in the longitudinal direction may save plotting paper and reduce processing cost.The paper presents the seismic data processing method to create 3D seismic plotting data which can be displayed in the longitudinal direction.The method introduces that the drawing data set can be created by separating 3D post-stack data set,prolonging data record lengths,modifying the line number and merging 3D post-stack data set.Through real plotting,post-stack seismic sections of different lines may be displayed in the longitudinal direction.Therefore the processing method saves paper greatly and reduces processing cost.
