| 摘 要： | 非开挖工程常会遇到的淤泥质高粘土土层,施工中往往需要较大的剪切力才可以破坏土体,因此常常会导致钻杆扭矩过大,导向和扩孔难以进行,造成施工困难,延误工期等后果。针对此类地层,通过室内试验研究和对分子结构的作用机理的分析,介绍了一种应用到钻井液中能有效地解决该类地层中的高扭矩问题的常见二糖有机物,并在实际工程中得到有效应用。

| Abstract: | High viscosity silt soil strata have been often encountered in trenchless engineering.Great shear stress is needed to destroy the soil mass,thereupon many project accidents happened such as too large torque of drill pipe,difficult guided drilling and hole reaming with construction delay.In this paper,by the laboratory experimental study and the analysis on the mechanism molecular structure,a common disaccharide organic compound was introduced,which was applied in drilling fluid to effectively solve the high torque for drilling in viscosity silt soil strata. |
