摘　　要：研究将离子液体BMIM-Cl(1-丁基-3-甲基咪唑氯盐)用作甲烷水合物抑制剂,考察了不同质量浓度的BMIM-Cl溶液对甲烷水合物形成的抑制效果。结果表明,BMIM-Cl可抑制甲烷水合物生成,且抑制效果随其质量浓度的增大而增强。在w(BMIM-Cl)分别为50×10-6、100×10-6时和500×10-6时,它抑制甲烷水合物生成的时间分别为450min、620min和1000min。Ionic liquid 1-butyl-3-methylimidazolium chloride （BMIM-C1） was studied for use as methane hydrate inhibitor, and the effect of BMIM-CI concentration on inhibiting methane hydrate formation was investigated. The results showed that BMIM-C1 could inhibit the formation of methane hydrate and the inhibition effect increased with the concentration. When mass fractions of BMIM-C1 were 50x10^6, 100x10^6 and 500x10^6, the inhibition times were 450min, 620min and 1,000 min, respectively.
