摘　　要：在Ｚｕｏ－Ｇｏｍｍｅｓｅｎ－Ｇｕｏ水合物模型的基础上，通过简化和改进，将该模型扩展应用于同时含有盐和甲醇的水溶液体系中气体水合物生成条件的预测。结果表明，对于１２个含单盐（或多盐）和甲醇水溶液体系，预测的气体水合物生成总的压力平均相对误差为５．２７％。The Zuo Gommesen Guo hydrate model was simplified and modified in this work.The equilibrium hydrate formation conditions for twelve systems containing salts and methanol were predicted using the new model.It was found that the prediction and experimental data were in good agreement.The total average absolute deviation of formation pressure was 5 27%.It could be concluded that the extension of the simplified and modified Zuo Gommesen Guo hydrate model to the prediction of gas hydrate formation conditions for systems containing salts and methanol was feasible.
