摘要(Abstract)：
油藏与水平井段耦合的蒸汽辅助重力驱数学模型及其求解方法已经建立。本文在此基础上考虑建立沿水平井井筒方向上有质量、能量损失的一维多相管流数学模型。如果能研制相应的油藏模拟软件,可预测水平井蒸汽辅助重力驱蒸汽腔室的大小及形状的动态变化,模拟计算毛管力、蒸汽干度、地层深度等对蒸汽腔室发育程度的影响。
This paper is about solution method of mathematical model for SAG flooding with oil reservoir coupling horizontal well section. Based on this method, 1D multiphase conduit flow mathematical model along the direction of well bore of horizontal well can be established. If the corresponding oil reservoir simulation software can be developed, the dynamic changes for the size and shape of steam compartment during horizontal SAG flooding can be predicted, and the effect of capillary force, steam dryness and formation depth on the steam compartment can be simulated and calculated.
