摘　　要：特殊结构井在作业过程中容易出现岩屑床堆积问题,进而诱发井下复杂情况。传统的岩屑床清除方法存在效率低、成本高的不足,目前国内外逐渐开始采用井眼净化工具解决特殊结构井作业过程中的岩屑携带问题。综合调研了国内外井眼净化工具研究现状和应用情况,分析了现有井眼净化工具的技术优势和不足,指出了井眼净化工具的研究方向:一是高效率,减少井眼净化工具的入井数量,降低环空压耗;二是智能化,实现地面对井下工具的智能控制。In drilling special structure well, one common problem is the building-up of cuttings beds, which often leads to down hole problems. The traditional methods of cuttings removal have a number of problems, such as inefficiency, high cost. At present, hole cleaning tool has been grad- ually adopted for removing cuttings beds. Therefore, the research progress and application of hole cleaning tools at home and aboard are reviewed, and technical advantages and disadvantages of dif- ferent tools are analyzed. Finally,a summary of future research is ended with in this paper,which focuses on high efficiency and intellectualization hole cleaning tools.
