【摘要】 随着石油开采程度的不断加深,勘察地下隐伏的地质构造显得尤为重要,特别是那些对石油勘探与开发有重要影响的断层.由于地震数据的采集受到多种因素的影响,降低了数据质量和信噪比,干扰断层解释的准确性.本文采用的基于图像处理的地震断层增强技术,能够减少各种随机因素的影响,使断层刻画得更清晰,边界轮廓更清楚.该技术主要是在图像信息提取的基础上,利用地震剖面的方向和各向异性等信息,进行广义Kuwahara滤波,达到对断层增强的目的.该技术在断层解释方面有较好的应用价值.更多还原

【Abstract】 As the deepening oil exploitation of degree,investigation of insidious underground geological structure is particularly important,especially those faults has an important impact on the exploration and development of oil.However,seismic data are affected by various kinds of factors in the progress of data acquisition,which reduces the SNR of the seismic data,and then interfere with the accuracy of interpretation of the geological structure.This paper is based on image processing of the enhancement of fault of technique.It could reduce the impact of random factors and depicte the fault and the boundary more clearly.The technology combine the image of the anisotropy and the orientation and so on with generalized Kuwahara filter in order to the fault enhance on basis of the image of the information extraction.The technique in the interpretation of the construction of fault has a most important value.更多还原
