煤田三维地震综合解释技术应用研究

本文以矿方建设高效、安全生产的现代化矿井要求为出发点,阐述了三维地震解释技术的发展,指出了地震多属性提取和波阻抗反演技术应用的实际意义,通过对陕北某矿三维地震勘探的应用实例,提出了地震多属性提取技术在预测煤厚、煤层冲刷范围等方面具有较好的应用效果;根据波阻抗反演技术在河南某矿的应用实例,提取了全区煤层顶板波阻抗值,并与钻孔揭露的岩性之间建立一定的对应关系,实现了对全区煤层顶板岩性的预测.

Applied Research of Multi-interpretation Technology in Coal Field with 3D Seismic Exploration

Based on the constructed efficiency and producted safety modern mine requirements as a starting point, the article elaborated on the development of 3D-seismic interpretation technology,and pointed out the practical significance of seismic multiple attributes extraction and wave impedance inversion technology. Through the application of 3D-seismic exploration in a mine of the northern ShaauXi province,it proposed that seismic multi-attribute extraction technology had a good application effect in the prediction of coal thickness, coal seam scouring scope and so on. According to the application examples of wave impedance inversion technology in a mine which lied in HeNan province,author extracted the wave impedance values in the coal seam roof,and revealed certain corresponding relationship between lithology and drilling,su as to realize the lithology prediction of the coal seam roof.
