428XL仪器炸药震源和可控震源交替施工探讨

Discussion about alternate performance of explosive source and vibroseis on the 428XL instruments

在428XL仪器中,两个blaster接口可以同时配接炸药震源与可控震源控制器,因这两种震源在系统中对应不同的处理类型,而仪器在载入SPS文件时只能引用一种处理类型。为了实现两种震源的交替生产,在系统中必须能同时引用两种处理类型。本文介绍的参数文件修改法与多线束施工法,能实现同时引用两种处理类型,从而达到两种震源交替生产的目的。

In 428XL instruments, the two blaster interfaces can simultaneously connect explosive source and vibroseis con- troller, owing to their different process types in the seismic system. But the instruments only apply only one kind of process type when importing sps files. In order to achieving the alternate performance of the two seismic sources, system should accept the two kinds of processing types simultaneously. This paper introduced in detail about the method that the 428XL instruments using two kinds of processing types in the same time.
