摘要
表面活性剂凭借其具有亲油基和亲水基的特殊结构,能够吸附在油气水三相界面,达到改变润湿和降低界面张力的作用,这一性质被广泛应用在油气田开发的各个领域。本文综述了钻井完井表面活性剂、注水开发表面活性剂以及复配表面活性剂在不同场景下的相关机制及其应用的研究进展、目前存在的问题与发展趋势,并总结表面活性剂相关机制的应用实例,为扩展表面活性剂在未来油田开发领域中的应用提供一定的参考。
Surfactant(SA),with its special structure of oily and hydrophilic groups,can change the wetting and reduce the interface tension through adsorption to the oil-gas and water three-phase interface.This property is widely used in various fields of oil and gas field development.This paper summarized the research progress and application trend of SA in different scenarios and the existing problems and development trends were also studied.By summarizing the application examples of SA related mechanisms in different problems,it provided some reference value for expanding the application breadth of SA in the future oilfield development application.
