| 摘 要： | 内蒙古东乌旗阿吉勒铅锌矿区地层复杂，钻进过程中经常遇到多个构造破碎带，以凝灰岩和碳质板岩为主，蚀变发育，在泥质、硅质胶结段极易遇水膨胀、水化分散，造成坍塌、缩径等护壁难题。在采用多种冲洗液效果不理想的情况下，试验应用了植物胶低固相冲洗液，达到较好的防塌效果，且适应性强、粘度适中，形成的泥饼薄而致密且有韧性，成功地解决该矿区钻孔护壁难题。以ZK1507钻孔为例，阐明了所采用的冲洗液在水敏性地层取得明显的防塌效果。

| Abstract: | The strata of Ajile Pb-Zn mine are complex in Dongwu Banner of Inner Mongolia and multiple tectonic fracture zones were encountered in drilling process. Tuff and carbonaceous slate are the main components of the strata with alteration developing; water swelling and hydration dispersed were extremely easy to happen in muddy and siliceous cement segments, which caused lots of wall problems such as collapsing, necking and so on. In the case that the effects of a variety of flushing fluid are not ideal, the test and application were made on the low solid plant gum drilling fluid, good anti-sloughing effect was achieved with strong adaptability and moderate viscosity, the thin mud-cake formed was dense and flexible to successfully solve the wall protection in this mining area. Taking the example of ZK1507, the paper describes the obvious anti-sloughing effect of the drilling fluid used in the water sensitive strata, which could be applied in the actual production. |
