【摘要】 地震数据在采集处理过程中不可避免地会受到各种因素的影响,从而导致地震资料的信噪比低,造成断层信息模糊,断层增强的目的是进一步清晰地刻画断层,同时提高地震资料的信噪比.本文提出了方向性边界保持断层增强技术,首先通过方向滤波技术估计地震同相轴的方向信息,然后结合边界保持滤波技术进行断层图像的增强,将该技术用于地震资料,可以得到断层图像更加清晰、分辨率更高的三维地震相干体,以利于进一步的构造解释以及油气输导体系的定量评价,具有重要的理论与应用价值.更多还原

【Abstract】 Seismic data are often influenced unavoidably by various kinds of factors in the course of data acquisition, which reduces the SNR of the seismic data and increases the difficulty of fault recognition. The purpose of fault enhance is to describe the fault clearly and improve the SNR of the seismic data at the same time. Orientational edge preserving fault enhance technology is proposed, seismic event direction information is estimated by orientation filter at first, and then edge preserving filter technology is combined to enhance fault information. Applying this technology to the seismic data and clearer fault information with good continuity of seismic coherence can be acquired. This technology is helpful for structure interpretation and petroleum transportation system quantitative evaluation, thus possesses very important theory and application value.更多还原
