Due to the long development time of CO2 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 CO2 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.
