摘　　要：经过计算分析比较,特高含硫天然气水化物形成温度比不含硫天然气水化物形成温度高。对特高含硫天然气而言,硫化氢含量越高,对水化物形成温度影响越大,且随压力的降低,硫化氢含量越高对水化物形成温度影响得越大。其中二氧化碳含量的高低,对水化物形成温度影响不大。Calculation and analysis results results show that hydrate formation temperature of natural gas with very high sour content is higher than hydrate formation temperature of natural gas with little sour content.Higher H_2S in natural gas with very high sour content has less affect on hydrate formation temperature,which is more evident as pressure drops.CO_2 in natural gas has less affect on hydrate formation temperature.
