摘要
OBN由于其独立采集的特点,正成为在深水OBS海洋地震采集的主流方法.,OBN点位定位精度是决定地震资料好坏的主要因素之一,本文主要介绍新型声学定位系统超短基线(USBL)工作原理,工作过程,以及在OBN作业中的使用方法和应用效果.
Abstract
OBN is becoming the mainstream method for OBS Marine seismic acquisition in deep water due to its independent acquisition characteristics.OBN point positioning accuracy is one of the main factors that determine the quality of seismic data.This paper mainly introduces the working principle and working process of the ultra-short baseline(USBL)of the new acoustic positioning system,as well as its application methods and application effects in OBN operations.
