摘要
随着OBN海上石油勘探活动的日益增加,OBN勘探作业中如何更好地获取节点仪器设备点位基于平均海水面的水深数据变得尤为重要。本文应用Arc GIS平台,根据OBN勘探作业过程中实时记录的水深数据建立了海底的数字高程模型;根据水下节点设备的位置信息,从海底数字高程模型中提取对应位置的高程值,从而减少了水深踏勘的工作量,提高了生产效率,最后利用数据对比说明了数据质量。
With the development of OBN offshore seismic exploration activities,how to measure the seabed elevation and get better data becomes particularly important.This paper based on the real-time water depth data which recorded during the operation of OBN exploration,use ArcGIS to establish the seabed DEM(Digital Elevation Model).According to the position of the node,extracted the seabed elevation from the DEM,so as to reduce the work of water depth exploration and improve the production efficiency.Finally,the data comparison was used to illustrate the data quality.
