XX地区火山岩发育区地震资料处理技术应用

摘要

The volcanic rocks in the XX area are developed and the quality of seismic data is poor. By tackling the seismic data in this area,the influence of the shallow surface volcanic rocks on the seismic data is weakened,and the signal-to-noise ratio of the data is greatly improved. This paper introduces the technical problems in data tackling,and solves the problem of complex static correction,low signal to noise ratio,the difference among amplitude,frequency and phase,velocity modeling and imaging through the use of supporting technical means.%XX地区火山岩发育,地震资料的品质较差,通过对该区地震资料进行攻关处理,削弱了浅表层火山岩对地震资料的影响,较大幅度地提高了资料信噪比.本文主要介绍资料攻关中面对的技术难题,通过采用配套针对性技术手段,解决资料存在的复杂静校正问题、低信噪比问题、振幅、频率和相位的差异问题、速度建模及成像问题.
