地震勘探空气枪悬挂拖曳系统综述
|
摘要
空气枪作为水域地震勘探的一种具有良好激发特性和环保特点的无污染激发震源被工业界广为使用已经多年。按照完成地震勘探采集任务要求,空气枪需要按照气枪阵列组合方式进行模拟设计。为了取得所需的激发能量,与不同结构的船舶配合、在不同海域施工可以采取形式多样的阵列设计、气枪悬挂方式和阵列拖曳模式。文章对目前几种常用的空气枪悬挂拖曳系统进行了分析与论述。
Owing to the excellent and stable firing characters,the airgun system,as a kind of non-polluting marine energy source,has been widely used by marine seismic exploration for many years.In order to optimize seismic survey field data acquisition,the applied airgun array must be designed by using special marine source modeling software.The versatile airgun array modeling,array hanging mechanism and towing methods about the airgun systems have been used to suit different vessels.This paper describes several ways of array hanging and towing systems that can be referenced by the people concerned.
