节点设备无桩号地震采集的测量方法
|
摘要
地震采集技术的发展日新月异。随着同步扫描技术、节点设备在地震采集中的应用,地震采集对物探测量的方法和质量控制也提出了新的要求。国外某项目采用无桩号施工方法,使地震采集的各个环节得以数字化,在一定程度上改变了以往的物探测量施工方法。新的施工方法对于工区的各种信息要求更加全面、更加准确,因此测量的工作内容变得更加丰富,要求也更高。本文从无桩号地震采集施工的震源导航、节点放样导航、GSR节点定位、车辆导航设备以及施工方法和质量控制等方面进行了论述。
With application of the seismic acquisition technologies of synchronous sweep and node devices,the new seismic surveying methods and quality control methods are also required.stackless acquisition method used in one abroad project has made all procedures of seismic acquisition fully digital and completely changed the previous seismic surveying method.Recording,vibrates navigated and positioned autonomously,and surveying group change duty from locating the position of receiver and source points to prepare design data in advance for a variety of positioning equipment,quality control and post data processing.Moreover,the new acquisition method requires more comprehensive and accurate information in working area,and thus measure the content of surveying becomes more abundant and higher demands.This article introduces the surveying equipments for vibrator navigation,node device navigation,GSR positioning and vehicle navigation,operation methods and quality control methods for stackless acquisition operation.
