摘　　要：本文建立了油藏三维地应力场的数学模型。在此模型中，岩石为弹塑性介质，模型考虑了油藏开发过程中温度变化和油、气、水三相流体压力的变化以及岩石的自重对应力的影响。计算温度时考虑了热传导以及流体在多孔介质中的对流换热。在计算流体压力时，考虑了油、气、水三相压力。The mathematical model of 3-dimentional stress field in the oil reservoir has been established. In this model, the rock is regarded as elastic-plastic material. The factors affectingstress field in the oil reservoir development, such as temperature, pressure of the fluid, areconsidered. The effect of the rock gravity on stress is included also. Heat conduction and thermal convection of the fluid through the porous rock are considered in calculating temperature.The pressures of three phases of oil, water and gas are included in the fluid pressure.
