摘　　要：随着钻井技术的不断发展、钻井深度的不断加深、钻井地质条件的不断复杂化,现有的钻井液已不能满足要求,一些学者提出了在水基钻井液中加入不同类型的聚合醇,从而优化现有的钻井液,达到满足复杂条件下的需求,优化钻井液性能。对常规的钻井液的性能进行了概述,描述其不足之处,以及新的需求;并且对在钻井液中使用的聚合醇的性能进行了阐述,合成的钻井液必须具备一定的润滑、防塌、保护油层的效果。With the continuous development of drilling technology,the deepening of drilling depth and the increasing complexity of drilling geology,the existing drilling fluid can no longer meet the requirements.Some scholars have proposed to add various types to today’s water-based drilling fluids.The polymerized alcohol optimizes the existing drilling fluid to meet the needs of complex conditions and optimize drilling fluid performance.The performance of conventional drilling fluids is outlined,the shortcomings and new requirements are described;and the performance of the polymerized alcohol used in the drilling fluid is described.The synthetic drilling fluid must have certain lubrication and protection.The effect of collapse and protection of the oil layer.
