一、前言自喷石油井中流体的流动是两相垂直管流。在石油开采时,油藏、井筒和地面集输的总压力损失中,井筒的垂直流动阶段占有主要部份。早在1930年,就已有气-液两相流的理论问世。开始,这种分析是局限的,应用范围也有限。1952年Polttman和Carpenter发表了《Multiphaseflow of gas and water through verticalfloe strings》,1963年Duns和Ros发表了 I. INTRODUCTION Flow of fluid from a jet-oil well is a two-phase vertical flow. During oil production, the vertical flow of the wellbore occupies the major part of the total pressure loss from the reservoir, wellbore and ground transportation. As early as 1930, the theory of gas-liquid two-phase flow had existed. Initially, this analysis is limited, the scope of application is limited. 1952 Polttman and Carpenter published “Multiphaseflow of gas and water through verticalfloe strings”, Duns and Ros published in 1963
