地震采集测量高程异常的发现与处理

Discovery and Processing of Height Measuring Anomaly in Seismic Data Acquisition

测量高程数据应用于地震勘探数据采集、数据处理及数据解释,其高程精度对地震数据的影响较大。阐述在地震数据采集过程中,物探监督通过专业软件发现高程异常,经室内测量环节检查、测量原始数据检查、测量专业监督检查,确认导致高程异常的原因,提出复测,并对全工区的测量作业提出要求。

Height measuring is applied in the acquisition, processing and interpretation of seismic exploration data, and its accuracy has great influence on seismic data. In seismic data acquisition process, the height anomaly is found using special software. In geo- physical supervision, the causes leading to the height anomaly are determined by laboratory inspection of measurement link, crude data and professional supervision, and the suggestion to the measurement operation in the whole work area and the requirement of re- measurement are proposed.
