Abstract: This paper describes a device of ~(113)Sn-~(113m)In application to logging of total liquid production profiles.The technical specifications of ~(113)Sn~(113)In; Radioactivity of ~(113)Sn not less than 1.11x10~9Bq, working period, not less than four months, elution efficiency>70%, working temperature 4—45℃, storage temperature>0℃.The device can undergo the rocking of a rough road. The eluate of ~(113m)In can be applied on site. The operation is very convenient and safe. The eluates do not pollute environment and can get high logging efficiency.
