两相管流工艺计算软件的研制

利用流体力学理论，结合目前国内外最新的两相流理论和实验研究成果，在描述气液两相管流水力计算、热力计算和流型判断的数学物理模型的基础上，研制出适用于海洋、沙漠、丘陵地区，原油与伴生气、凝析天然气与凝液混合输送工艺的一套新的计算模拟软件TFTCS．对TFTCS的结构、功能、适用范围作了介绍，用该软件对某湿天然气管线进行了模拟计算，同管线生产数据进行了对比，并与国外同类软件PIPEPHASE进行了对比验算。实际应用表明，该软件功能完善、操作方便、计算结果可靠，能满足油气混输管线的设计计算和生产管理的需要。

Development of Technology Calculation Simulator for Two-phase Flow in Gas-liquid Hybrid Pipeline

According to the basic rule of fluid mechanics and in combination with the latest domestic and foreign research results of two-phase flow theoretically and experimentally, a new simulator TFTCS has been successfully developed which covers the hydraulics calculation , thermodynamic calculation and flow regime prediction. The TFTCS can be used to technology calculations in the oil/associated gas or condensate gas transmission pipeline of offshore, desert and hilly zone. The software's structures, functions and ranges of application are introduced,and simulative calculation is made on a submarine wet gas pipeline with TFTCS.The results are examined by comparing with producing data of a submarine pipeline or through a comparison calculation with the foreign same kind software PIPEPHASE. The example analysis shows that the TFTCS is easy to use and have reliable calculation results, can satisfy the need of oil-gas hybrid pipelines'engineering design calculation and operating management.
