摘要: 从动量定理角度出发建立求解蒸汽压降方程,而从能量守恒角度出发建立求解蒸汽干度变化的方程,采用节点分析方法和数值计算方法对模型求解.计算过程中借鉴传统的气液两相流Beggs-Brill方法计算水蒸汽混合物的物性参数.通过对辽河油田齐40块和杜80块10口井井筒的压力、温度和干度分布计算表明该模型计算精度较高.

Abstract: The steam pressure equation is deduced with the momentum theorem while the steam quality equation is deduced with energy balance.The model is solved with nodal analysis and numerical calculation.The property parameters of the steam mixture are calculated with the traditional Beggs-Brill method.The calculation results are compared with the detection on 10 steam injection wells (Qi 40 and Du 80)in Liaohe Oil Field,which indicates that this model works well in calculating the steam properties of steam injection wells.

Key words: heavy oil thermal recovery, injected steam, vertical wellbore, distribution of pressure, distribution of temperature, distribution of quality
