一种地震属性切片滤波
|
摘要
随着三维地震的开展,目前研究地震数据从原来的剖面延伸到了平面,但往往由于采集、处理等影响,地震平面属性切片往往会有纵横向的印记,这些印记会破坏数据的平面连续性,不利于进行平面地震相解释。为了去掉平面属性的纵横向印记,提高平面属性的连续性,可采用数字滤波技术。该文中使用一维和二维的平面属性滤波去噪方法,并对二者的滤波效果进行比较,证明二维滤波去噪效果更好。因此,可将二维滤波应用于对平面地震属性切片的处理。
With the development of 3D-Seismic,the research on seismic data extends from section to plane now.But the slices of seismic plane attribute always have marks in inline and crossline direction because of the influence of the process of data acquisition and processing.These marks will damage datas' plane continuity and affect the process of the plane seismic facies interpretation.In order to get rid of these marks,improve plane attributes' continuity,the paper adopts digital filtering technique.This paper utilizes the methods of plane attributes' one-dimension and two-dimensional filtering.Through comparing the results of them,the paper demonstrates that two-dimensional filtering is better.Wherefore,it is necessary to process the slices of seismic plane attribute by two-dimensional filtering.
