| 摘 要： | 在固体岩心钻探过程中,水泥护壁是一种较常用的护壁方法,同时也是一种不易操作控制好的护壁工艺,根据水泥浆的性能及其在孔内的流动性,结合ZK3901孔的实际灌注经验,进行综合分析、比较,得出结论——在不同孔深,选用不同的灌注方法和不同水灰比的水泥浆,会取得不同的护壁效果。

| Abstract: | Cementing protection is a common method of borehole wall protection in solid core drilling,but it is not an easy process at the same time.According to the slurry performance and its fluidity in the borehole,analysis and comparison were made with practical grouting experience in ZK3901.It was concluded that when different grouting method and slurries with different water-cement ratio were applied at different hole depth,the wall protection effects were different also. |

| Keywords: | core drilling borehole wall protection with cementing grouting method formula water-cement ratio |
