开发并应用了一种数值热多相井筒流动模型。该配方需要一维空间（轴向）和时间离散化，并包括耦合质量守恒方程的油，水和气体成分，三相流体流动，能量守恒方程，和压降关系。采用漂移通量模型来表示流体相之间的滑移。该模型被实施到储层模拟器中，以实现完全耦合的储层-井筒模拟。一系列的数值结果，包括验证对以前的实验结果，验证对分析模型，并模拟复杂的热多相流的情况下，涉及垂直和多边威尔斯井耦合油藏模型。总的来说，这些数值模拟结果证明了新的井筒流动模型的广泛适用性和鲁棒性。(C)2009年由Elsevier BM出版。
A numerical thermal multiphase wellbore flow model is developed and applied. The formulation entails one-dimensional spatial (axial) and temporal discretizations and includes coupled mass conservation equations for oil, water and gas components, three-phase fluid flow, an energy conservation equation, and a pressure drop relationship. A drift-flux model is employed to represent slip between fluid phases. The model is implemented into a reservoir simulator to enable fully coupled reservoir-wellbore simulations. A series of numerical results are presented, including validation against previous experimental results, verification against an analytical model, and simulations of complex thermal multiphase flow scenarios that involve vertical and multilateral wells coupled with oil reservoir models. Taken in total, these numerical simulation results demonstrate the broad applicability and robustness of the new wellbore flow model. (C) 2009 Published by Elsevier BM.
