摘要
为提高低渗透油田采收率、攻克生产过程中的结垢腐蚀等问题,实现油藏的高效开发,不可避免地会用到油田化学剂,但目前已投入现场使用的油田化学剂大多为有机试剂,其会对环境造成极大的污染。随着人们环保意识的提高,新型环保型油田化学剂已成为热点研究方向。碳量子点(CQDs)具有良好的亲水性、低毒性、生物相容性、较稳定的物理化学性质,在油田化学领域具有广阔的应用前景。本文综述了CQDs在驱油剂、缓蚀剂、阻垢剂以及杀菌剂等油田化学剂领域的研究进展及作用机理,讨论了碳量子点化学剂残余浓度的检测方法,以期为CQDs在油田化学领域的应用提供参考。
In order to enhance the recovery rate of low-permeability oil fields, overcome problems such as scaling and corrosion caused by development and utilization, and achieve efficient development of oil fields, it is inevitable to use oilfield chemicals. However, most of the organic reagents currently used on site can cause significant environmental pollution. With the increasing awareness of environmental protection, the research on the new environmentally friendly oilfield chemicals have become a hot topic. Carbon quantum dots (CQDs) have superior characteristics including good hydrophilicity, low toxicity, biocompatibility, and relatively stable physical and chemical properties, and have broad application prospects in the field of oilfield chemistry. This paper provides an overview of the research progress and mechanism of CQDs in oil-displacing agents, corrosion inhibitors, scale inhibitors, and fungicides, and also discusses the methods for detecting residual concentrations of CQDs chemical agents, which are supposed to provide reference for the application of CQDs in the field of oilfield chemistry.
