【摘要】 在地震勘探数据处理中,人们通常认为同时提高信噪比与分辨率是一对难以解决的矛盾。针对这一问题,在数据处理中引入了保边去噪这一方法。并在地震剖面上作了保边去噪与平滑滤波的对比试验。试验结果表明:相对平滑滤波而言,保边去噪处理可较真实地反映地下地质结构,保持裂缝储层地震波场的运动学和动力学特征,使上述矛盾得以部分解决。最后还利用保边去噪进行了某区的裂缝检测,从检测的平面图上来看,效果较好。更多还原

【Abstract】 Generally, people deem that signal/noise ratio improvement and resolution improvement are very contradictory each other in seismic data processing. Facing this problem, we bring edgepreserving to seismic processing. After making edgepreserving and smooth filter trial on seismic section, we can draw the following conclusion: comparing with smooth filter, edgepreserving can mirror geological shape authentically and keep kinetic characteristic and dynamical characteristic very well. As a result, the contradiction can be solve parlty. In addition, we applied edgepreserving to some zone’s fracture detection and got a good result.更多还原
