摘　　要：通过对超声成像测井过程中因测井仪器工作出现偏心状况而造成采样图像中出现垂直暗条特征的分析,提出针对此类问题的偏心修正算法,分别通过理论分析与实际测井资料的处理验证并进行效果比对.实践证明:该方法为进一步改善井径图像成像质量、提高后期测井资料解释处理的精确度提供了有效的解决方案.In the analysis of well logging by ultrasonic imaging, under eccentric condition of logging instrument in the process of work, the sampled image will appear vertical dark strip features. To solve this problem, we put forward the eccentricity correction method. By comparing the theoretical analysis and the actual validation of logging data, it proves that the method offers an effective solution for further improving the caliper imaging quality, increasing the accuracy of the latter interpretation and processing of logging data.
