摘　　要：本文综述了几年来国内外有关井壁失稳机理和一些新型防塌泥浆作用机理研究的文献，由此归纳出防塌泥浆作用机理的一些共同规律，为泥浆防塌处理剂新的作用机理的研究和建立提供具有启发性的思路。This paper is a comprehensive review of the mechanisms of borehole instability and stabilization by some novel water based antisloughing drilling muds on the basis of recent literature data published in China and abroad. The topics covered are: trends and features in researches; target for mud developing; reasoning borehole instability induced by chemical factors; mechanisms of stabilizing borehole by oil based muds; functions of some novel antisloughing water based muds (alcohol alkoxylated systems; glycol muds; PVA/catalyst system; silicate base muds; cationic polymer muds; artificial consolidation of instable zones); common rules of borehore stabilization utilising antisloughing mud systems.
