摘　　要：为了对天然气水合物相平衡进行相关研究,实现对不同压力(温度)条件下水合物临界生成温度(压力)的迅速计算,有必要研究和开发天然气水合物相平衡预测软件。利用VB语言面向对象可视化的特点,并结合分子热力学模型法,编制纯水中水合物相平衡预测软件;同时利用软件对混合组分气体生成水合物的相平衡进行分析比较。软件界面简洁,操作简单,通过简单的输入输出操作,可在短时间内完成相应的计算。结果表明,软件对于混合组分天然气水合物的相平衡预测较为准确,其相对误差控制在1%以内,对工程实践有较强的指导意义。It is necessary to research and develop the software for phase equilibrium prediction of natural gas hydrate in order to study natural gas hydrate phase equilibrium, and obtain a pressure （temperature） of hydrate rapidly corresponding to the different temperature （pressure） conditions. With the use of VB, which is object-oriented and visible, combined with the method based on molecular thermod- ynamic model, study and prepare the prediction software of pure water gas hydrate equilibrium; To compare the phase equilibrium of mixture gas hydrate formation with the software. The software interface is simple, easy operation; with the input and output of simple op- eration, can complete the corresponding calculation in a short time. The results show that the software component of the mixed gas hydrate phase equilibrium prediction is more accurate, and the relative error is controlled within 1%, for engineering practice has a certain significance.
