摘要
为使油田井筒传热问题的研究结果能更加精准地指导工程实践,须建立高精度井筒传热模型。本文综述了建模中涉及的井筒温度场模型、井筒多相垂直管流压降模型以及井筒温度-压力耦合模型的国内外发展历程和研究现状,其中井筒温度场模型研究方法又分为半瞬态法和全瞬态法。在RAMEY等的原始模型基础上,国内外学者们建立了考虑井液相变、井液与管壁的摩擦和焦耳-汤普森效应等前人忽略掉的众多因素的模型,且模型依然具有计算简便的特点,在指导工程实际问题时可供合理选择并联系实际进行完善。
In order to make the research results of oil field wellbore heat transfer more accurately guide the engineering practice, it is necessary to establish a high-precision wellbore heat transfer model. In this paper, the development history and research status of wellbore temperature field model, wellbore multiphase vertical pipe flow pressure drop model and wellbore temperature-pressure coupling model involved in modeling at home and abroad were summarized. The wellbore temperature field model research methods are divided into semi transient method and full transient method. Based on the original model of Ramey et al., scholars at home and abroad have considered many factors neglected by predecessors, such as the well fluid phase transition, friction between well fluid and pipe wall, Joule-Thompson effect,and so on. Moreover, the model still has the characteristics of simple calculation, which can be used for reasonable selection and can be improved according to the actual situation when guiding the practical engineering problems.
