Radial temperature distribution in production oil wells

SHI Ying~1,SONG Yan-jie~1,XING Li-bo~2(1.Geoscience College,Daqing Petroleum Institute,Daqing,Heilongjiang 163318,China;2.Institute of Petroleum Exploration and Development,Daqing Oil field Corp.Ltd.,Daqing,Heilongjiang 163712,China)  
Being informed of downhole temperature distribution is very important in knowing producing development and producing condition.On the basis of the energy conservation equation,based on the heat transfer theory of continuous medium and porous medium,the 2-D mathematical models of downhole temperature field in cylindrical coordinates have been constructed for production wells.Proper initial and boundary condition wellbore parameter and formation property parameter are selected.Downhole temperature distribution with multiple pay zones in different distance from producing oil wellbore have been simulated by finite difference algorithm,and simulated result corresponds to general knowledge,which is the theoretical basis for further observing oil field production condition.
