| Abstract: | The EMDS-TM-42E gamma-electromagnetic defectoscope imported from Russia is an engineering logging tool to inspect casing damages and is used through tubing. Mainly, it is used to describe deformation, fissure and other defects of tubing and casing. As is known, the primary causes which effect the data are wrong depth of investigation and noises. So, analyzed are the reasons resulting in the wrong depths and signal noises, based on which we proposed two ways to solve these problems. Finally, we give some practicable advice for the defectoscope logging operations to improve the original logging data quality. |
