摘　　要：国外油田服务公司生产的井眼清洗工具在我国油田使用时功能单一,针对不同碎屑没有针对性的收集方案,打捞效果不佳。为此,研制了多功能井眼清洗工具,并在油田进行了现场试验。该清洗工具含有2个收集腔,通过不同大小碎块的沉降速度不同来分级收集,独特的分屑设计使得碎屑不会回落井底,且根据作业量的大小可适当增加收集腔的长度,有效地保证单次作业效率。现场试验结果表明:该工具可在磨铣桥塞作业中有效收集磨铣产生的碎屑,整个作业平稳,安全可靠,且在作业过程中节省了工作液,大大降低了作业成本。所得结论可为井眼清洗工具的进一步优化提供参考。The wellbore cleaning tool of foreign service company features single function,no specific collection schemes for different debris and poor fishing performance. To address the issue,a multi-functional wellbore cleaning tool has been developed and been tested on-site. The new wellbore cleaning tool,with two collection chamber,could collect different fragments of various sizes with different sedimentation rate. The unique debris classification design makes sure the debris would not come down to the bottom hole. The length of the collection chamber could be appropriately increased in accordance with the amount of work to ensure the efficiency of single job.Field test results show that the tool could effectively collect debris generated by milling bridge plug with smooth,safe and reliable operation,saving the working fluid and significantly reducing operating costs. The study could provide references for further optimization of wellbore cleaning tools.
