优化OBC电缆连接上船方式
|
摘要
海上OBC地震采集使用的仪器设备,需要通过电缆将铠装电缆与甲板电缆进行连接。在观测系统及施工参数(包括炮点距、炮线数、排列滚动线数、炮船船速等)确定的前提下,电缆的连接方式成为船队提高生产效率的关键问题。船队根据以往的施工经验,制定多种方案,优选高效率、低风险的电缆连接方式,提高了船队的生产效率。
For ocean seismic acquisition,the cable used to be equipped on the vessel.Based on determinate the observation system and construction parameters,such as shot point interval,numbers of shot line and rolling line,source vessel velocity etc.,the method of cable connection became the key factor in enhancing efficiency for OBC crews.By fully using of previous experiences,multiple plans are made for choose out the connection method with the highest efficiency and lowest risk to enhance production efficiency.
