摘要
掌握井下的温度分布,对于了解油井的生产动态和监测油井的生产状况有着重要意义.根据能量守恒方程,依据连续介质和多孔介质的传热机理,建立了生产油井井下温度场在柱坐标系下的二维数学模型;选取了适当初边值条件、井筒参数和地层物性参数,采用有限差分法模拟计算了多个产层的生产油井井下径向不同位置的温度分布,计算结果符合一般认识,该研究为监测油田的生产动态提供了理论基础.
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.
