本文介绍了第一次尝试推断洋流的形状地震拖缆使用真实的数据。它表明,当没有横向转向时,在每个炮点使用总最小二乘解来推断洋流是可行的。当存在横向转向时,推断的电流中存在一些假象;这被认为是由估计拖缆速度的误差引起的。本文描述了构成代价函数的残差方程,并讨论了如何根据物理准则选择代价函数中的权值。正确选择权重是一门艺术,需要进一步的研究来实现自动化和鲁棒性。
This paper describes the first attempt to infer ocean currents from the shapes of seismic streamers using real data. It demonstrates that it is feasible to infer the ocean currents, using a total least‐squares solution at each shotpoint, when there is no lateral steering. There are some artefacts in the inferred currents when there is lateral steering; this is believed to be caused by errors in estimating the streamer velocity. This paper describes the residual equations that form the cost function and discusses how to choose weights in the cost function based on physical criteria. Correctly choosing weights is something of an art and requires further research to make automatic and robust.
