【Abstract】 The calibration position of cement bond log (CBL) is hard to be determined,the author analyzes the reason causing the problem and improves the current calibration method,realizing CBL successful calibration in one run,making the normalization and autocommunization of CBL calibration possible,and reducing the influence by induced factors. Aiming at the problem of base line shift of CBL,the author develops a method that uses software to trace the actual CBL signal base line. The method ensures that the CBL results reflect the actual cement bond quality and it is proven reliable and effective by practical applications.更多还原
