摘要

在分析了现阶段煤田物理模拟地震数据特征的基础上,针对物理模拟数据处理过程中因换能器特性导致的振幅指向性及波形畸变问题实现了振幅补偿及波形畸变校正,对物理模拟地震数据中的多次波、虚反射干扰及宽频问题经过测试制定了合理的处理方案,最后在此基础上提出了针对煤田地震物理模拟地震数据的高精度成像流程,并通过某地区房柱式采空区物理模拟地震数据处理验证该流程可以有效提高煤田物理模拟地震数据的成像精度.

Abstract

Based on the analysis of the characteristics of the current coal field physical simulation seismic data,the amplitude compensation and waveform distortion correction caused by the characteristics of the transducer during the processing of physical simulation data are realized,and a reasonable processing scheme is developed for the multiple waves,ghost interference and broadband problems in physical simulation seismic data.Finally,a high precision imaging process for coal field seismic physical simulation seismic data is proposed,and the imaging accuracy of coal field physical simulation seismic data is verified by the processing of house-pillar goaf physical simulation seismic data in certain area.
