摘要

在石油天然气勘探开发中,由于断层和裂缝等地质特征是发现和描述油藏的基础,所以分辨和分析地震数据中这些地质特征是非常重要的。本文提出的一种保边界的最大一致性倾角扫描去噪方法,可以在很好地保留地质边界特征的情况下,有效地压制噪音,准确地拾取地层倾角信息,提高油气藏识别的精度。
Highlighting and analyzing the geological features of faults and fractures in seismic data is particularly important for hydrocarbon exploration and exploitation since they are often essential for finding and delineating reservoirs. We apply edge-preserving smoothing (EPS) to seismic processing and propose a most homogeneous dip-scanning method. The method preserves the geological features, eliminate random noise efficiently, obtain dip information, and improve the accuracy of identifying the oil and gas traps.
