摘要

在深海进行拖缆数据采集过程中,往往产生许多辅助数据和地震数据,为了确保数据的质量,必须对这些数据进行实时现场质量监控。本文以Pioneer三维拖缆船为例(Pioneer三维拖缆船数据记录系统是SERCEL公司SEAL系统,船载处理系统是ProMax),通过分析拖缆船三维地震数据采集的道头数据和对应的现场处理系统,开发了船载现场处理质量监控的功能,形成了一套有效的拖缆数据采集的船载系统质量控制技术。实践应用表明,这套质量监控方法有利于保障地震资料采集的质量和生产时效的提高。
In deep sea seismic acquisition,a large amount of auxiliary data and seismic data were acquired,in order to ensure the data quality,on-site quality control of those data has to be done. In this paper Pioneer 3D streamer boat was taken as example (its recording system is SEAL from SERCEL,and its on-site processing system is ProMax),by analyzing header data acquired in the boat and corresponding on-site processing system,on-site processing quality control function was developed,and an effective quality control technical workflow for the streamer acquisition system was established,application of the workflow shows that the technical workflow does help to ensure the acquired seismic data quality and the acquisition efficiency has been raised since using the technical workflow in the deep sea seismic acquisition.
