In conventional drifting and scraping ,different types of pipes need to be used which complicates process and reduces working efficiency .Based on the comprehensive analysis of the well repairing techniques ,a new kind of multi-tool for drifting and scraping was developed .It can realize various operation just in one trip ,such as drifting ,scraping ,pressure testing,direct and indirect flushing ,etc.The tool has been used in field and achieved desired effect in saving time and cost ,improving efficiency ,cutting down reservoir -invaded time by workover fluid .
