Joule-Thomson Effect on Heat Transfer in CO2 Injection Wellbore
Abstract:
Ramey model is a classical wellbore heat transfer model. However Ramey model did not consider Joule-Thomson effect. In this paper, Ramey model is improved by considering Joule-Thomson effect. The results show that Joule-Thomson effect will cause fluid temperature higher due to a positive Joule-Thomson coefficient and pressure rise. Injection temperature has little effect on fluid temperature. Fluid pressure is influenced by fluid viscidity. Higher injection pressure leads to faster pressure increasing speed.
