摘　　要：无标记物探作业无需在地面做任何标记,具有节省人力成本,降低安全风险,减少环境损害等优势,是未来石油物探导航定位的一种新模式。在传统无标记施工的基础上,结合节点技术和激光雷达技术发展,给出了两种探索性方案。一是在节点仪器中记录GNSS原始数据,通过后处理获得高精度节点坐标;二是对节点记录的单点定位结果进行滤波平滑,获得亚米级平面位置,再利用激光雷达数据对高程数据进行替代,从而获得节点的高精度坐标。Stakeless geophysical operation does not require any markings on the ground,which has the advantages of saving labor costs,reducing safety risks,and reducing environmental damage.It is a new model for future petroleum geophysical navigation and positioning.On the basis of traditional stakeless,combined with the development of node technology and LiDAR technology,two exploratory solutions have been proposed.One is to record the GNSS raw data in the node instrument and obtain high-precision node coordinates through post-proces-sing;The second is to filter and smooth the single point positioning results recorded by nodes to obtain sub meter level plane positions,and then use LiDAR data to replace elevation data to obtain high-precision coordinates of nodes.
