摘　　要：国外某石油勘探项目首次采用VSC导航进行可控震源施工,对队形中多台可控震源正常停点和偏点提出了新要求。为此,研发人员针对这些新要求对VSC导航进行了功能升级,通过增加测线角度定义和测线附着两个新功能,满足了施工要求,有力地保证了项目顺利开工和高效运作。本文以该二维项目施工为例,对VSC采用多台可控震源组合施工时的队形定义以及具体设定方法进行了介绍,重点介绍了为施工技术要求而开发的两个新功能及相关参数的设置。For the first time,a foreign oil exploration project has adopted VSC navigation for vibroseis operation,which has put forward new requirements for the normal stopping and deviation points of multiple vibroseis in the pattern.To this end,the R&D personnel have upgraded the functions of VSC navigation in response to these new requirementsby adding two new functionsof line angle definition and line attachment,to meet the construction requirements,and effectively ensure the smooth commencement and operation of the project.This article takes the construction of this two-dimensional project as an example to introduce the formation definition and specific setting methods of VSC construction with multiple combination,and focuses on two new functions developed for the technical requirements of construction and the setting of related parameters.
