Research on quality control of seismic shot records ofnodal seismic survey acquisition
The seismic surveyusing nodal blind acquisition technology is based on its flexible application in various com-plex environments,low equipment and personnel investment,no receiver channel limit,no need to wait for troubleshoot time during the acquisition process,long battery life cycle of nodes,and fast recovery of node QC reports.It achieves cost reduction and efficiency in seismic exploration acquisition construction,leading the development trend of the seismic survey acquisition industry.However,due to the limitations of current node equipment and technology,the shot record data received by the node cannot be collected in real-time and in a timely manner.Generally,it is necessary to wait for the node to collect all the requiredshot record data before recycling the node for data processing and analysis.Unable to monitor the quality of shot recorded data in a timely manner,unable to accurately find out the detonator shooting,weak shot,and other phenomena,unable to re-drill for unqualifiedshots in a timely manner,forming a principled quality haz-ard.This article comprehensively analyzes the seismic wave data recorded by the up-hole geophone of the blaster on that day and theshot data with different offsets recorded by each shooter connecting two nodes on that day.It accurately mo-nitors the weak shot phenomena such as shooting with only detonator and incomplete explosion on a daily basis,and takes timely re-drill for unqualified single shots,effectively ensuring and improving the quality of blind seismic survey data acquisition with nodes.
