摘　　要：综述了聚合醇(多元醇)钻井液的作用机理和特点。聚合醇(多元醇)的作用机制包括浊点效应、降低滤液化学活性和吸附机理等。聚合醇(多元醇)钻井液体系具有较强的抑制性、良好的润滑性、钻速快、防止和消除钻头泥包、对地层损害小、环保性能好和配伍性好等特点,对此作了详细评述。The mechanisms and characteristics for the polyglycol-based drilling fluid have been reviewed.The mechanisms include the turbidity point effect,lowing the chemical activity of the filtrating fluid and the adsorption,et ac.The polyglycol-based drilling fluid system has a series of good properties,such as strong inhibition,good lubrication,rapid drilling speed,minimizing bit balling,protecting the oil layer and environment,and good co-operation effect with other additives.These properties were all remarked in detailes in this paper.
