摘　　要：介绍了近年来改性原有添加剂后形成的新型水合物添加剂,从改性的方式到作用效果和机理,提供了一个完整的改性过程的理论概述。总结了改性添加剂作用于水合物生成的关键控制机制,对特定水合物的工程设计提供了指导。改性添加剂可加速或减缓水合物的形成过程;其中,—SO_(3)—磺酸基官能团(类似于十二烷基硫酸钠中的亲水基团)改性的纳米粒子在稳定纳米悬浮液、促进水合物生成方面的效果突出。This paper focuses on new hydrate additives formed by modifying the original additives in recent years. From the way of modification to the effect and mechanism,a complete theoretical overview of the modification process is provided. The key control mechanism of modified additives on hydrate formation is summarized,which provides guidance for engineering design of specific hydrate.Modified additives can accelerate or slow down the process of hydrate formation. Among them,the nanoparticles modified with —SO_(3)— sulfonic groups(similar to the hydrophilic groups in sodium dodecyl sulfate sodium lauryl sulfate) have outstanding effects in stabilizing nano suspension and promoting hydrate formation.
