| 中文摘要:山西古交矿区钻探施工中遇到严重漏失现象，采用传统的粘土球、水泥球、快干水泥、801堵漏剂加木屑等材料堵漏方法，均无效果，经过摸索和实践，采用聚丙烯酰胺+切削膏进行堵漏，取得了很大的成功，施工效率高、施工成本低、堵漏效果好，同时还减少了钻具的磨损，沉淀了钻渣，净化了冲洗液。 |

| Abstract:Traditional clay ball, cement ball, rapid hardening cement and lost circulation additive with sawdust were ineffective for drilling construction in a mine of shanxi, while polyacrylamide and cutting grease brought high efficiency with good sealing effect and low cost, which could reduce the drilling tool wearing, precipitate the drilling waste and purify the washing fluid. The paper briefly introduced the sealing method and the application result. |
