| 摘 要： | 基于护壁材料对浆液的流变性和失水及造壁性的影响，通过室内试验，研究了适用于煤系复杂地层的护壁浆液——膨润土-高聚物浆液。采用正交试验法得出护壁浆液的优化配方:5%膨润土+0.3% SM植物胶+0.04%聚丙烯酰胺（PAM）+1%腐植酸钾（KHm）。将这种高聚物低固相泥浆用于现场试验，在煤系复杂地层的钻探护壁中取得了良好的效果。

Research and application of well wall-protecting slurry in drilling in complex formation of coal measures |
| |
| Abstract: | Starting from the point of view to solve the difficulties of drilling, the paper studies the well wall protecting slurry in coal-bearing complex formation. Through the indoor test study of bentonite-polymer slurry system, then adopting the method of orthogonal test, the optimization formula of wall-protecting slurry was obtained. Finally the slurry of high polymer of low solid phase was used in field test, achieved good results in well wall protection during drilling in coal-bearing complex formation. |
