The Method of Image Dynamic Intensify and Morphing in Imaging Log

YAN Jian-ping~1,SHOU Xiang-yun~1,SHAO Zai-ping~2,YAO Sheng-xian~3,ZHAO Zhong-ming~3(1.China University of Petroleum,Dongying,Shandong 257062,China;2.Shengli Well Logging Company,Dongying,Shandong,257096,China;3.Sichuan Well Logging Company,Chongqing 400021,China)  
Imaging log is used widely for its higher discernibility,but the firsthand image usually reflect formation feature indistinctly.Static state normalization image is applicable to display logging response with large variable range and lithology analysis result.Dynamic intensify image increases its definition in borehole zone,but makes the image step-shaped because of the use of narrow window.Both of smoothing filtering or re-sampling cannot remove the step.Based on histogram local equalization method,this paper utilizes Morphing technique to do linear interpolation to the color data to smooth the step.The result shows that the step problem can be effectively resolved in this way.
