408UL/XL仪器的蛇形排列在三维地震勘探中的灵活应用

The Agile Use of Snaking Layout of 408UL/XL Seismograph in Seism Exploration

三维地震勘探,在一些地表条件特别复杂的地区,采集排列有时需要通过高速公路、航道河、水库.这种排列的布置十分困难,它不仅要增加工作量,而且施工效率很低.408UL/XL仪器的蛇形排列(Snakinglayout)能够为这样地表条件特别复杂的地区施工带来极大的便利,本文通过施工实例,阐述了408UL/XL仪器的蛇形排列在三维地震勘探中的使用方法.

In some area of complex surface conditions,the gathering lines of the three dimensional seismic survey,sometimes can pass through the highway,the route river,the reservoir and so on.It is extremely difficult to lay this kind of arrangement so that increas-es the work load and reduces working efficiency.The Snaking Layout of 408UL/XL seismograph can lead to the enormous convenience of seismic acquisition in such area of complex surface condition for seismic prospecting.For example,using Snaking Layout we just need to lay a transmission cable of Seismic Area Network for solving the problem of the many seismic gathering lines passing simultane-ously through the highway.This paper shows howSnaking Layout is applied to the field seismic acquisition by an example.
