Temperature Variation Across The Wellbore in SAGD Producer

摘要

Temperature measurements are widely used for SAGD real time monitoring.Nevertheless field DTS data demonstrates presence of the strong temperature variations across the SAGD producers and therefore introduce uncertainty in interpretation of the temperature data.This work is devoted to the numerical analysis of the generation mechanism for temperature variation across producer,estimation of the magnitude of such temperature variations.Methodology for numerical evaluation of temperature variation across the SAGD producer wellbore was developed.The simulated temperature variations were found to be in good agreement with the field data.
