煤炭精细三维地震处理技术的应用研究

An Applied Research on Fine 3D Seismic Data Processing Technology in Coal Prospecting

某研究区为实现综合机械化安全开采,迫切需要查证断距小于5m的断层分布情况。通过分析原始资料,提出了在地震数据处理技术、处理流程及参数选择方面要以保护地震数据动力学特征为原则,对整个数据体实施保真保幅和提高分辨率处理,重点作好高精度动、静校正工作。通过精细煤炭三维地震处理技术在研究区的应用,实现了主要煤层(13-1、11-2、8)地震波的高精度成像。

To realize fully mechanized safety mining,find out minor faults with displacement less than 5m is urgently needed.Through source data analysis,a principle to protect seismic data dynamic characteristics in aspects of seismic data processing technology,processing procedure and parameter selection put forward.To whole data volume carry out fidelity,amplitude preserved and resolution improved processing and put emphasis on high precision dynamic and static corrections.Through the application of the fine 3D seismic data processing technology in coal prospecting study area,has realized main coal seams（Nos.13-1,11-2 and 8） seismic wave high precision imaging.
