摘　　要：常规通井与刮削分别下2套管柱,操作工序多、作业效率低,通过对修井作业工艺综合分析,研制出新型通井刮削多功能工具,实现了1趟管柱进行通井、试压、刮削、正反洗井多种作业功能,在现场应用中,能够减少作业时间、降低作业成本、提高作业效率,减少修井液对油层侵害时间。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 .
