Abstract:

The paper presents the influence of various parameters of oil-water flow in a horizontal well on the intensity of the interfacial heat exchange. The stratified flow regime with a one-dimensional computational model is analyzed. It is demonstrated that the distance required for the full alignment of the phase temperatures can be tens or hundreds of meters. Thermal conductivity and viscosity of oil, as well as the angle of inclination, have the greatest influence on the intensity of the interfacial heat exchange with the stratified flow regime. For more information on the production rate and composition of inflows for the study of such wells it is recommended to use temperature sensors distributed over the cross section of the well.
