摘要

The effect of temperature on nuclear magnetic resonance (NMR) logging while drilling (LWD) has been studied. Heat conduction and permeability effects in the near wellbore invasion zone have been taken into account. Analytical solutions and numerical calculations have been exemplified and verified with the use of NMR LWD field data.
