海底地震勘探测线设计与实现

Design and implementation of ocean bottom seismic survey line

测线设计是海底地震勘探过程中必不可少的环节,设计的常规测线和声学定位测线是作业过程中作业船航行的主要参考线。海底地震勘探过程中使用的常规测线和声学定位测线一般为直测线或者折测线,本文详细阐述了直测线的设计原理及方法,并且分别叙述了忽略拐点和凑整拐点这两种不同拐点处理方式的折测线的设计规则,以及声学定位测线的相应设计流程。此外,本文通过编程实现了相应的常规测线和声学定位测线设计功能,经检验,设计成果合格,可以推广使用。

Survey line design is an essential step in the process of Ocean Bottom Seismic(OBS),and the designed conventional and acoustic positioning lines are the main reference lines for the navigation of the work vessel du-ring the operation process.The conventional and acoustic positioning lines used in OBS are generally straight lines or poly-lines.This article elaborates on the design principles of straight lines,and separately describes the design rules of poly-lines that ignore inflection points or match inflection points,as well as the corresponding design process of acoustic positioning lines.In addition,this article has implemented corresponding conventional and acoustic positioning line design function through programming.The function has been tested and the design results are qualified,so it can be promoted for use.
