| 中文摘要:大牛地气田石盒子组泥岩发育，钻井液抑制性不足，易发生井壁失稳事故，严重影响施工安全和施工进度。在分析石盒子组泥岩段失稳机理的基础上，开展了钾铵基聚合物钻井液抑制性研究。放大蒙脱石和伊蒙混层矿物含量，评价和优选出具有高效抑制性的钾铵基聚合物钻井液体系。该体系具有较低的线性膨胀率和较高的滚动回收率，对大牛地气田预防泥岩段井壁失稳具有重要的实际意义。 |

| Abstract:Mudstone developed in Shihezi group of Daniudi gas field and the inhibitive properties of the drilling fluids are poor, construction safety and progress are seriously affected by borehole instability. Based on the analysis on the instability mechanism, a study on the inhibition of potassium amino polymer drilling fluid was made. Mineral contents of montmorillonite and illite mixed layers were increased to evaluate and optimize higher inhibitive potassium amino based polymer drilling fluid system, which has lower liner expansion ratio and higher roll recovery and is of great practical significance to prevent borehole instability of mudstone section in Daniudi gas field. |
