Abstract
The temperature distribution in a reservoir with hydraulic fracture is studied by numerical modeling of transient temperature fields taking into account the Joule-Thomson effect and the adiabatic effect. It is shown that the presence of hydraulic fracture in the reservoir leads to a nonmonotonic temperature variation in the reservoir temperature: as the well pressure decreases, the temperature first decreases due to the adiabatic expansion of the fluid and then increases due to the Joule-Thomson effect. As the water-oil displacement front approaches the wellbore, the temperature decreases slightly due to the heat exchange processes in the fracture-reservoir system.
