摘要

An analytical transient wellbore-temperature-distribution model that was previously approximated in the literature is solved exactly for either initial or boundary conditions in two different regions of position/time. In addition, the model is extended to include conduction effects and is solved explicitly for both initial conditions (ICs) and boundary conditions (BCs). The three solutions are compared and discussed. In the process, the fundamental temperature and momentum equations are made dimensionless to analyze the process of approximation quantitatively. Also arising from this analysis are the primary dimensionless parameters and scales that affect the solutions.
