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。
In the exploration and development of oil and natural gas, it is very important to distinguish and analyze these geological features in the seismic data because the geological features such as faults and fractures are the foundations of the reservoir. In this paper, a maximum consistent dip scan noise denoising method with preserving boundary can effectively suppress noise, accurately extract information of formation dip angle and improve the accuracy of reservoir identification, while retaining the geological boundary features well.
