巨厚黄土层覆盖区二维地震找煤参数选取研究及应用

摘要

本文基于在类黄土塬巨厚黄土层覆盖及地下水位较深地区二维地震数据采集质量较差、资料处理过程困难的现实 [1],通过河南省荥巩煤田三李深部煤炭勘查区地震参数试验研究,阐述了在地震参数选取及资料处理过程中采取的技术措施.通过适合本区的激发与接收因素及合理的观测系统获得了信噪比较高的原始资料,取得了理想的地震地质成果.为今后在类似地区寻找煤炭资源提供参考.%Based on the poor quality of 2D seismic data acquisition on the loess tableland areas with deep underground water level, and in the reality of difficult data processing, this paper expounds the technical measures of seismic parameters selection and data processing, through the coalfield seismic parameter test and research on SanLi deep coal exploration area in Xinggong coalfield, Henan Province. A high signal noise ratio original data has been obtained by a reasonable observation system and suitable excitation and receiving factors, providing a reference for the future coal resources exploration in similar areas.
