Numerical Simulation Of Heat Transfer In Reservoir Porous Media

This project has been supported by the National Science Foundation (No: 50776014).Oilfield development practice shows that high ultimate recovery could be obtained in water flooding oilfield. Studies always concern about the development effect of water-flooding reservoir, but studies in terms of the thermodynamic view to explore the law of heat and mass transfer are rare. In this paper, the Fluent software is used to conduct numerical simulation of heat and mass transfer in terms of the thermodynamic view in reservoir porous media. It mainly includes the following elements:(1) Introduce the thermal physical properties of oil, water and rock, the basic parameters of oil&water flowing in porous media and the research methods for heat and mass transfer of oil&water in porous media systematically;(2) In order to explore heat and mass transfer laws of oil and hot water in the reservoir porous media, this article simulated from a macro perspective. Firstly macro-physical and mathematical model are set up to carry out the numerical simulation, and the flow regulation of oil and water is analyzed. From the field of velocity, pressure and temperature, it can be seen that the flow effect of water is much better than that of oil. Finally the effect of the thermal properties of oil, water and rock to the heat and mass transfer law is studied;(3) In order to explore the displacement law of oil & water two-phase flow in the reservoir porous media, this article simulated from a micro perspective. Firstly physical and mathematical model was set up, numerical simulation studies and the displacement effect analysis was carried out based on different parameters, and the results show that: the rock's wettability and oil&water's interfacial tension are the most important parameters that can affect the micro heat and mass transfer;(4) Introduce the basic characteristics of fractal, fractal dimension and the utility of the fractal theory in the reservoir simply.
