建立了直井和小斜度井中多相流分析的数值模型。该模型通过计算油气水三相井中各相的速度、体积流量、压力、流体特性等流动参数随深度变化情况来模拟油井内三相流的流动。 A numerical model for multiphase flow analysis in vertical well and small inclined well was established. The model simulates the flow of the three-phase flow in the oil well by calculating the flow parameters such as velocity, volume flow, pressure, fluid properties and other parameters along with the depth of the oil-gas-water three-phase well.
