Abstract

Wellbore fluid temperature distribution is the important foundation of oil/gas well test and analysis, production optimization design and performance analysis. Due to its complexity and partly unavailable accurate data, the theoretical temperature prediction model is of little application. Based on the previous research, a newmodel was constructed by taking the unsteady state heat transfer in formations into consideration. In this way, the uncertainty of wellbore fluid temperature calculation due to overall heat transfer coefficient could be avoided. The example shows that the prediction of this newmodel is better in both wellbore fluid temperature change under different circumstance and accurate time length required to reach stability.
