This research aims to improve the prediction of temperature fields in wellbores during fluid circulation using an analytical model.
Developed a 1D unsteady energy equation for drilling fluid and a 2D radial transient conduction model for surrounding formation.
Coupled both domains through interface boundary conditions for closed-form solutions.
Validated model predictions with finite element simulations and field measurements.
Validated closed-form solutions show agreement with finite element simulations and field data.
Model reduces computation time by two to four orders of magnitude compared to traditional methods.
Parametric analyses indicate circulation time and formation properties control thermal disturbance extent.
