【摘要】 随着科学技术的发展,海洋油气勘探目的层由浅部向深部发展。工业化生产要求采用的拖缆长度越来越长,但是受到外部环境的影响,如海流和障碍物的影响,长缆不易在海上施工。如果采用双船作业,就可以通过调节船距来控制拖缆的最大偏移距,从而实现长缆作业。其次,随着勘探需求的增加,宽方位和广角反射勘探成为解决某些特定地质问题的手段。本文旨在对几种应用比较成熟的双船作业关键技术进行分析。更多还原

【Abstract】 With the development of science and technology,the target layer of marine oil and gas exploration changed from shallow to deep operation,therefore required the longer and longer streamer lengths,but the external environment,such as flow and obstacle,will influence the long streamer working.The undershooting mode can used to adjust the boat distance then to control the maximum offset of longs streamer,in addition,a wide range and wide angle reflection exploration can be used to solve some specific geological problem means.This paper introduced the application of several kinds of advanced and sophisticated technologies of undershooting streamer.更多还原
