【摘要】 结合拟地震数据处理思想,提出多极叠加观测方式下多极三维偏移处理技术,利用多道电阻率测深数据进行拟地震记录分析,通过划分网格单元在等位球面进行电阻率值叠加,实现异常电阻率值的空间归位。实际应用表明该处理技术可以从巷道后方观测数据体中充分提取工作面前方地质体的电阻率分布特征,超前预测预报效果显著。更多还原

【Abstract】 Imitating the data processing method of seismic wave,multi-pole 3D excursion technique is proposed according to the multi-pole stack observing system.Pseudo-seismic approach was applied to the multi-path resistivity sounding data.By stacking resistivity on the equipotential surface girding,abnormal resistivity is put correct location.Application revealed that the resistivity distribution ahead of the tunnel is precisely abstracted from the surveying data back of the tunnel using 3D migration processing.Its effect is very obvious.更多还原
