在油气管道多相流模拟中，热力计算是与水力计算相互作用的重要环节，它影响着程序的收敛性和计算结果的准确性。能量方程的形式是热力学计算的关键。从油气管道流动的能量方程出发，推导了油气稳态温度计算的显式温降公式。新的能量方程考虑了焦耳-汤姆逊效应、压力功、摩擦功以及地形起伏和传热的影响。石油和天然气科学与技术--IFP能源新版本与沿线沿着环境。因此，它是一个整体形式的能量方程，能够准确地描述多相混输管道的实际情况。为此，对现有文献中关于管道油气两相流温度计算的一些观点进行了评述。消除了温度迭代循环，并将显式温度方程而不是焓能量方程集成到共轭水力和热力计算中，以提高算法的效率。该计算既适用于组分模型，也适用于黑油模型。将该模型分别引入组分模型和黑油模型中，并对英迈-牙哈和陆丰两条实际管道进行了仿真，将仿真结果与OLGA计算结果和实测结果进行了比较。结果表明，该模型能很好地模拟出温度场的分布。最后分析了油气比热容对流体混合物温度的影响以及焦耳-汤姆逊效应对管道温度分布的影响。结果表明，焦耳-汤姆逊系数是描述油气两相流动的一个关键因素。
In the simulation of oil-gas pipeline multiphase flow, thermodynamic computation is an important process interacting with the hydraulic calculation and it influences the convergence of the program and the accuracy of the results. The form of the energy equation is the key to the thermodynamic computation. Based on the energy equation of oil-gas flow in pipeline, the Explicit Temperature Drop Formula (ETDF) is derived for oilgas steady state temperature calculation. This new energy equation has considered many factors, such as Joule-Thomson effect, pressure work, friction work and impact of terrain undulation and heat transfer Oil & Gas Science and Technology – Rev. IFP Energies nouvelles with the surroundings along the line. So it is an overall form of energy equation, which could describe the actual fact of multiphase pipeline accurately. Therefore, some standpoints in literatures on the temperature calculation of oil-gas two-phase flow in pipelines are reviewed. Elimination of temperature iteration loop and integration of the explicit temperature equation, instead of enthalpy energy equation, into the conjugated hydraulic and thermal computation have been found to improve the efficiency of algorithm. The calculation applied to both the component model, also applied to the black-oil model. This model is incorporated into the component model and black-oil model, respectively, and two simulations are carried out with two practical pipeline Yingmai-Yaha and Lufeng multiphase pipeline and the temperature results are compared with the simulation calculated by the OLGA and the measured. It is shown that this model has simulated the temperature distribution very well. Finally, we analyzed the influence of the specific heat capacity of oil and gas on the temperature of the mixture of fluids and the influence of the Joule-Thomson effect on the temperature distribution on the pipeline. It is shown that the Joule-Thomson coefficient is a key factor to well describe the oil-gas two-phase flow.
