DigiFIN系统在海上三维地震勘探中的应用
|
摘要
在深海多缆拖缆三维地震作业中,由于受海流影响,每条电缆之间的间隔会超出技术标准的要求,造成面元覆盖不均匀,导致补线率增加,影响作业效率。DigiFIN系统在深海多缆三维地震勘探中,可控制电缆间距,提高面元覆盖质量,通过去噪方法的有效组合,在固体电缆上产生的噪音对地震资料品质不构成影响。
When multi-streamers are used for 3D marine seismic acquisition in the deep water, the separation between each streamer is beyond the requirement of technical standard due to the effect of ocean current, which will lead to the nonuniform binning coverage, increased infill and the low operational efficiency. In the 3D marine seismic survey, DigiFIN, a lateral control system can control the interval between each streamer, improve the binning coverage quality. The noise from solid streamer will not affect the seismic data quality by the effective combination of the de-noising method.
