New exploration of petroleum exploration stake-less
Stakeless geophysical operation does not require any markings on the ground,which has the advanta-ges 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 devel-opment of node technology and LiDAR technology,two exploratory solutions have been proposed.One is to re-cord 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.
