遥感数据和地理信息系统在地震数据采集中的应用
|
摘要
在复杂地表条件下,如何优化地震测线部署和观测系统设计,合理选择试验点,监控野外施工质量,合理组织、安排生产设备与施工班组以及HSE管理等系列问题一直是野外采集工作的难点。为此,利用高分辨率遥感影像与数字高程模型(DEM),并结合地理信息系统(GIS),形成一套综合技术;探讨了其在油气地震勘探采集设计、监控生产动态和生产质量等方面的应用情况。应用结果表明,采用该套技术后地震勘探采集设计更加科学,采集设备和施工班组的安排更加合理,有助于在复杂地表条件下获得高品质的地震资料。
Seismic acquisition is challenging in areas with complex surface conditions,and the main problems include the optimization of seismic line emplacement and the design of observation system,the selection of experiment location,the quality control of field operation,the arrangement of equipment and working shifts,as well as HSE management.High resolution remote sensing data,digital elevation model(DEM) and geographic information system(GIS) are applied to seismic data acquisition design,performance monitoring and quality control.The results show that these technologies can improve the design of seismic data acquisition,optimize the arrangement of equipment and working shifts,and enhance the quality of seismic data acquisition in the areas with complex surface conditions.
