摘　　要：地震采集中震源和仪器记录的同步性质控对地震资料采集质量至关重要。实际地震采集过程中,由于设备的迭代发展,震源与仪器记录的同步性方面有了较高发展,反而在质控过程中容易忽略。一旦发生非人为设置造成的同步误差,会直接影响到采集资料的质量。而且同步误差通常难以准确测量,造成后期数据处理中无法予以精准消除相应误差。本文主要结合中海油服所使用的设备以及在实际施工过程中出现的问题,探讨触发信号异常和GPS授时系统出现异常造成的同步误差发生原因及相应的解决方案。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.
