摘　　要：为降低压裂施工摩阻,提高非常规储层的压裂改造效果,在系统调研国内外关于压裂用减阻剂文献的基础上,综述了减阻剂的类型和减阻机理,分析了减阻性能的影响因素,介绍了减阻剂的现场应用情况和减阻剂主要存在的问题,并提出了减阻剂未来的发展方向。结果表明:目前常用的减阻剂主要存在成本高、性能不稳定、减阻机理不明确的问题;低成本、对储层伤害低、减阻性能高效的多功能型纳米复合减阻剂将是未来减阻剂研究的重点和热点。通过对减阻剂的全面研究,可为目前减阻剂性能的提升、新型减阻剂的研发和非常规油气的开采提供可行性的帮助。In order to reduce the friction of fracturing construction and improve the effect of unconventional reservoir fracturing,based on the systematic investigation of domestic and foreign literatures on drag reducing agents used in fracturing,the types and mechanism of drag reducing agents were reviewed,the influencing factors of drag reducing performance were analyzed,the field application of drag reducing agents and the main existing problems of drag reducing agents were introduced,and the future development direction of drag reducing agents was proposed.The results show that the main problems of the current commonly have problems such as high cost,unstable performance,and unclear drag reduction mechanisms.The multi-functional nano-composite drag reducer with low cost,low damage to reservoir and high drag reduction performance will be the focus and hot spot in the future research of drag reduction agents.Through the comprehensive study of drag reducing agents,it can provide feasible help for improving the performance of current drag reducing agents,the research and development of new drag reducing agents and the exploitation of unconventional oil and gas.
