Quality Control Technology and Application of Underwater Positioning for OBN Seismic Acquisition
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.
