【摘要】 纹理分析是图像处理中的一项常用技术,通过对地震数据的标准化、体元划分等处理后,将该项技术应用到地震数据分析中,并在断层与河道的识别和刻画方面取得较好的效果,但对道内振幅变化关系及小断层细节刻画不是非常清晰.本文通过对算法的研究及程序开发,以单个体元为标准,并以奇数对称为准则,修改了数据标准化的方法,实现了模型数据测试,结果显示该技术能清晰刻画出道内与道间振幅变化关系;并在HL工区的进行应用,在河道与断层细节刻画方面取得较好的成果.通过体纹理属性的分析,较好的计算出了地震数据中道内与道间振幅变化的统计关系,尤其在细小断层或裂缝发育区,充分体现出了重新标准化后的纹理分析技术在分析河道及细小断层或裂缝上的优越性.更多还原

【Abstract】 Texture analysis is a common technology in image processing,which can be extended to the field of seismic data analysis by normalizing seismic data,dividing volume element etc.It achieved better effect in fault identification,channel detection,but,It’s not very clear of intrace relationship of amplitude and the details of small fault.Through the algorithm research and program development,With a single volume element as a unit,and the odd symmetry as a criterion,data standardization method modification,the model test is realized,so that this technology is great advantages in characterize both intratrace and intertrace relationship of amplitude;this method is applied in HL area and the better results on describing channel and fault detail are obtained.Through the analysis of volume texture attribute,the Statistical relationship both intratrace and intertrace of seismic data is better characterized,especially in small fault or fracture development zone,which fully reflects the advantages of renormalized of texture analysis technique on detection channel and small faults or cracks.更多还原
