The important application of synchronous quality control in Marine seismic acquisition
The synchronous quality control of source and instrument records in seismic acquisition is very important for data quality.In the actual seismic acquisition process,due to the iterative development of the equipment,the synchronization of the source and the instrument record has a high development.The synchronization error caused by non-human Settings will directly affect the quality of the collected data,and the synchronization error is usually difficult to measure accurately,resulting in the failure to accurately eliminate the corresponding error in the later data processing.Based on the equipment used by China Oilfield Service and the problems in the actual construction process,this paper discusses the causes of synchronization errors caused by abnormal trigger signal and GPS timing system and the corresponding solutions.
