摘要
海底节点位置坐标误差会直接影响OBN地震资料成像品质,需要采取措施对节点位置进行质控.文章分别论述了超短基线声学定位系统和长基线声学定位系统在放缆过程中和节点沉放之后对节点位置的有效质控,并通过实际案例阐述了OBN地震采集水下定位质控技术应用效果.
Abstract
Coordinate errors in the position of seabed nodes directly affect the imaging quality of OBN seismic data,and measures need to be taken to control the quality of node positions.This paper discusses the effective quality control of the ultra short baseline acoustic positioning system and the long baseline acoustic positioning system on the node position during the cable laying process and after the node sinking.And the application effect of OBN seismic acquisition underwater positioning quality control technology was explained through practical cases.
