摘　　要：水合物浆液流动时黏度较大,添加阻聚剂可起到一定降黏作用。研究吐温80和司班40作为阻聚剂对四丁基溴化铵水合物浆液黏度与热物性的影响。结果表明,添加质量分数为0.025和0.05的阻聚剂具有较好的降黏效果,同时可提高水合物相变温度、增大水合物占比、降低冰含量,从而实现浆液流动性的提升。The viscosity of hydrate slurry is large when it flows.The anti-agglomerant can play a certain role in reducing the viscosity.The effects of Tween 80 and Span 40 as anti-agglomerant on the viscosity and thermophysical properties of tetrabutyl-n-ammonium bromide hydrate slurry with different mass concentrations were studied.The result showed that the anti-agglomerant with the mass fraction of 0.025 and 0.05 had good viscosity reduction effect,which could improve the phase change temperature of semi-clathrate hydrate,increase the proportion of hydrate,and reduce the ice content,so as to improve the fluidity of hydrate slurry.
