Analysis of the changing characteristics of interfacial tension shows that condensate oil has low interfacial tension. When condensate gas well liquid loading is analyzed, wells are suggested to be divided into two types: oil-gas wells and oil-water wells. Oil-gas interfacial tension was used in calculation for oil-gas wells, while gas-water interface tension was used in calculation for oil-water wells. According to the well production state, the actual temperature and pressure were used to calculate the interfacial tension. Three general models were modified by considering the variable interfacial tension, and the critical flow rates were calculated for 20 gas wells of a condensate gas field in Xinjiang. The results show that the accuracy rate of critical flow rate calculated by the modified Turner's model reached 90%, which can be used as the judging standard of prediction of liquid loading in this region., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null, pdf=2BkjKrkkzdaiKJW3gyc+UA==, pdfFileSize=999250, pdfExtLink=null, richHtmlUrl=null, mobilePdfUrl=null, reviewReport=null, pdfFirstPage=null, abstractGraph=null, abstractGraphContent=null, abstractVideo=null, citation=null, cebUrl=null, magXmlContent=null, mapNumber=null, authorCompany=1.
