| 中文摘要:钻孔漏失是钻探施工中一直较难解决的难题，尤其是绳索取心钻进施工中的严重漏失，造成钻进效率低、施工成本高的后果，严重的直接威胁钻孔安全、甚至会导致钻孔报废。 Aus-Plug是2006年自国外引进的高效延时膨胀钻孔堵漏剂，Aus-Plug钻孔堵漏剂的使用较好地解决了我院绳索取心钻孔漏失的问题。2003年至今，根据我院用绳索取心钻进工艺在多个矿区试验及钻进施工中遇到的不同地层、不同漏失方式特点，通过多年生产实践，摸索和总结了绳索取心钻进施工中冲洗液漏失的危害及采用的一些堵漏施工方法。同时也总结了Aus-Plug钻孔堵漏剂在不同漏失情况下比较实用有效的应对堵漏方法，较快推动了我院绳索取心钻进工艺施工的应用和发展。 |

| Abstract:Circulation lost is a difficult problem in drilling construction, especially in wire-line core drilling. Severe circulation lost may lead low drilling efficiency and high construction cost, directly threaten the drilling safety and even result in drill hole abandoned. Aus-Plug was an effective delay expansion drilling plugging agent introduced in 2006, by which the circulation lost was well controlled. Since 2003, according to the different formations and lost situations encountered in the tests and construction in a number of mines and through years of practice, the hazards of circulation lost and some plugging methods were explored and summed up; and the practical and effective methods to deal with circulation lost in different geological conditions by Aus-Plug plugging agent also were summarized. |
