Abstract
The radial angular temperature distribution in a porous medium with nonuniform permeability is investigated by numerical simulation of nonisothermal filtration of live oil taking into account the degassing heat, the Joule-Thomson effect, and the adiabatic effect. It is shown that nonuniform permeability in the wellbore zone of the porous layer leads to anomalous cooling due to intense degassing in the well-permeable zone.
