摘　　要：本文从相态研究入手，用状态方程和相平衡计算描述流体在井筒中的相态变化，通过能量方程计算出井筒多相流压力分布以及油气水分布。本文方法适用于各种井筒（直井和斜井）以及各种类型的流体（黑油、挥发油、凝析气、湿气和干气）。Starting from phase behavior study this paper describes the phase change in a well bore by means of equation of state and phase equilibrium calculation, and the multi-phase pressure distribution as well as the distribution of oil, gas, and water in a well bore is calculated by using the energy equation. The techniques suggested in this paper can be applied in various well configuration (both conventional and deriated hole)and various fluids combination (black oil, volatile oil, condensate, wet and dry gas)
