摘　　要：CS油田泰州组、阜三段及戴南组油藏因CO_(2)驱开发时间较长,地层原油轻质组分经CO_(2)萃取后,导致生产油井结蜡情况加重,极易造成蜡卡躺井。针对此问题,重点对CS油田目前开发中所使用的的各种清防蜡技术进行分析及评价,总结各类清防蜡技术的特点与应用效果,证明现场各种清防蜡技术的使用效果显著,从而实现CS油井的平稳生产。Due to the long development time of CO_(2) flooding in the reservoirs of Taizhou Formation,the third member of Funing Formation and Dainan Formation,the wax deposition in production Wells is aggravated after CO_(2) extraction of light oil components,which is easy to cause wax sticking in Wells.This paper focuses on the analysis and evaluation of various paraffin removal methods and technologies used in the current development of CS oil field,and then summarizes the characteristics and application effects of various paraffin removal technologies,proving that the use of various paraffin removal technologies is remarkable,so as to achieve the stable production of CS oil Wells.
