注蒸汽采油高压模型水平井相似准则及模化

Similarity criterion on steam recovery high pressure model horizontal well and modeling

根据水平井井筒及井筒附近的流体流动行为,建立注蒸汽采油高压模型水平井变质量流模型,提出一套模化高压模型中水平井半径及射孔或割缝参数的相似准则体系,并将该相似准则体系应用到蒸汽辅助重力泄油(SAGD)三维高温高压物理模拟试验模型的设计上。结果表明,模拟试验数据可有效反映现场汽腔扩展规律和生产规律。

According to fluid flow inside and beside the horizontal wellbore,the variable mass flow model of horizontal well in steam recovery high pressure model was set up and a set of similarity criterions to design radius and perforating parameters were proposed.The proposed similarity criterions were used to design steam-assisted gravity drainage（SAGD） three dimensional high temperature and high pressure physical simulation experiment.The simulation results can reflect steam chamber development law and oil production law.
