Abstract

This study investigates how temperature profile changes with time during fluid circulation through the wellbore and annulus by using ANSYS Fluent, to help designing offshore cementing job in the petroleum industry. The use of two-dimensional nature of transient computational-fluid-dynamics (CFD) simulations shows that both flow rheology and fluid distribution in the well affect heat transfer calculations and such an effect is more pronounced at the bottom hole where the flow direction changes from downward to upward. When compared with one-dimensional (1D) simulation, multi-dimensional simulation results predict a longer time for heat transfer consistently, implying that simple 1D simulation techniques tend to under-predict the amount of time associated with cementing job. How fluid distribution within the well changes with time and how the resulting pressure and temperature calculations are affected at different times and locations are also visualized in this study.
