| 中文摘要:钻探工程中钻孔漏失常用纯水泥浆液进行堵漏，而针对矿区复杂地层钻进，漏失严重，易垮孔卡钻，为防止漏失及井内事故发生，必须使用高效的水泥堵漏浆液及合理的堵漏工艺。以道真新民铝土矿区为例，对水泥-粘土浆液护壁堵漏工艺进行研究，分析了水泥浆液中加入膨润土、水玻璃、减水剂后性能的变化规律，得出水泥堵漏浆液的优化配方。实际工程应用中取得了良好效果，大大提高了钻进效率。 |

| Abstract:Pure cement slurry has been used to plug leakage in drilling engineering. For the serious leakage, collapse and sticking in complex formations drilling, effective cement slurry and rational plugging technology must be used to prevent the loss of flushing fluid. The analysis is made on the performance variation of cement-clay slurry with bentonite, water glass and water reducing agent adding, and the optimized formulation of the cement-clay slurry is obtained, good effects have been received in the practical engineering project with higher drilling efficiency. |
