| 摘 要： | 平山湖矿区第四系、第三系地层属于遇水不稳定地层,钻探施工时,地层造浆严重、孔径扩大率高,造成钻探事故频发、施工效率低。采用以聚合物为主要添加剂的不分散低固相钻井液体系在该矿区进行了应用试验,有效地抑制了粘土造浆及泥页岩水化膨胀,取得了很好的效果。

| Abstract: | The quaternary and tertiary strata of Pingshanhu mining area are water encounter unstable with serious clay invasion and high borehole expansion rate while drilling;and all these result in frequent drilling accidents and low drilling efficiency.The application test was made on non-dispersed low solid-phase drilling fluid system with polymer as main additives,clay invasion and shale hydration swelling were effectively inhibited. |

| Keywords: | non-dispersible low solid-phase drilling fluid system clay invasion borehole expansion inhibiti performance Pingshanhu mining area |
