摘要
针对深海油气田由于饱和潜水员的下潜深度通常在300 m以内,无法依靠潜水员完成海底管线膨胀弯和跨接管的测量的问题,介绍长基线水下定位技术,利用该技术,南海某气田项目成功测量和安装了多条膨胀弯和跨接管。
With regards of conventional method for subsea pipeline spool piece and jumper distance measuring by means of using saturation diving equipment and flange gauge,deep-water oil and gas fields is not applicable due to the saturating diver generally is not able to reach 300 meters depth or more. A new and advanced measurement technique of spool piece and jumper,the long baseline（ LBL） underwater positioning technique was introduced. This technique is already used and successfully installed several spool pieces and jumpers in Yacheng13-4 project.
