摘　　要：中值滤波技术可以有效地去除随机噪声,增强水平同相轴的连续性,但其未考虑地层倾角的变化。断层/边缘增强滤波技术考虑到地层倾角的变化因素,能够突出细微差别,改善低信噪比资料,显著提高地震剖面质量。实践证明,断层/边缘增强滤波技术能更加突出地层接触关系,可以有效提高小断层的解释精度,提高煤田三维地震勘探资料解释的精度和准确性。Median filter technology application not only can effectively remove noise,but also enhances the coherent axis,but did not take into account the change of the stratigraphic dip.And fault enhancement filter technology and edge enhancement filtering technology based on the consideration of change of dip stand out the subtle nuances,improve low SNR,and significantly improve the quality of seismic profiles.Practice proves that the filter technology more prominent stratigraphic contact relationship,can effectively improve the interpretation accuracy of small faults,have improved accuracy that the 3D seismic prospecting of coal field data explains greatly.
