GeoMountain采集工程师表层调查软件及其应用

A surface survey software in the GeoMountain Acquisition System and its application

中国西部地区的表层结构复杂多变,这不仅影响了激发和接收,使野外采集难以获得较高信噪比的原始资料,而且也严重影响了地震资料的成像和振幅保真处理。针对该问题,GeoMountain采集工程师表层调查软件通过对微VSP、微测井、小折射和双井微测井等资料的人机交互处理和解释,实现了表层速度反演,建立了准确的表层物理模型,从而指导野外激发、接收,为静校正量计算提供了可靠的数据。从实际应用情况看,该软件是研究复杂多变近地表环境的有效工具。

The surface structure in West China is complicated and variable,which influences not only excitation and receiving in seismic exploration,thus making it hard to get original data with high SNR in field acquisition,but also seismic data imaging and amplitude fidelity processing.In view of this issue,the surface survey software in the GeoMountain Acquisition System,through man-machine interactive processing and interpretation of micro VSP,micro logging,mall-angle refraction as well as twin-well microlog,realizes surface velocity inversion and establishes an exact surface physical model,thus guiding field excitation as well as receiving and providing reliable data for the static method.Observed from its actual application,this software is an efficient tool to do research in complicated and variable near-surface environment.
