二维地震数据闭合方法新探

Newly probing of method for 2D seismic data closure.

地震数据闭合是二维地震资料处理过程中一项不可缺少的工作。以往地震数据处理员需要通过制作纸剖面进行手工闭合,这种传统方法不仅会引入人为闭合差,而且费时费力。本文提供一种运用Promax处理软件有关模块进行二维地震数据闭合的方法,具体包括准确求取交点文件、单点闭合、反交点闭合(断层上下盘,斜层)、多点闭合及环形闭合。

The seismic data closure is a necessary work in 2D seismic data processing. The former seismic data processor needs to carry out hand closure by making paper section. This traditional method not only introduced man-made mis-tie, but also is time-consuming and with an efforts. The paper presented a method that uses module relevant to Promax processing software to carry out 2D seismic data closure, and concretely including: accurately acquiring cross-point file, closure at single point, inverse cross-point closure (handing wall and heading wall of fault, tilted stratum), multi-point closure and circle closure.
