| 中文摘要:钻孔的护壁堵漏一直是深孔钻进中的技术难题，在小秦岭深部找矿项目钻探施工中，由于该地区区域地质较为复杂，且构造发育，岩石破碎，钻进过程中孔内经常出现掉块、塌孔、漏失等问题，泥浆堵漏效果不佳，施工中采用水泥浆护壁堵漏达到了良好的效果。本文针对小秦岭深部钻探项目水泥浆护壁堵漏技术的应用，对深孔岩心钻探水泥浆护壁堵漏技术进行分析与总结，提出深孔灌浆堵漏技术对速凝水泥浆性能的要求与施工技术要点，并对该矿区相关钻探施工提供指导与建议。 |

| Abstract:Wall protection and plugging has been technical difficulty in deep hole drilling. In the drilling construction for deep prospecting projects in Xiaoqinling, because of the complex regional geology with tectonic development and fractured rocks, block falling, hole collapse and leakage often occurred in drilling process and mud plugging effect was poor, while good result was achieved by slurry plugging in the construction. According to the application of cement slurry plugging technology for deep drilling projects in Xiaoqinling, the paper analyzes and summarizes wall protection and plugging technology for deep core drilling, puts forward the requirements of deep holes grouting and plugging technology to the performance of quick-setting cement slurry and gives advices to the related drilling construction in this area. |
