| 摘 要： | 测井数据中包含较多与地层信息无关的噪声,对正确认识地层有一定干扰。自适应中值滤波能有效地去除原始图像中的脉冲噪声并保存图像的细节和边缘信息。利用自适应中值滤波技术对声波测井数据进行了处理,结果显示,测井曲线分辨率得到提高,与岩心分析数据有更大的相关性;制作的合成记录精度更高,与井旁道的相关性更强。

| Abstract: | A lot of noise, which is unrelated to the formation, in logging data has some interference to the understanding of formation. The adaptive median filtering can effectively remove the pulse noise and preserve the details and edge infor- mation of the original image. The acoustic logging was processed by adaptive median filtering . The results show that the resolution of the processed logging is improved and has greater correlation to the core data. The synthetic seismogram made from the processed logging has higher precision and stronger correlation to the seismic trace near a well. |
