摘　　要：传统的黏度测量仪器无法保证水合物浆稳定存在所必须的高压、低温条件,因此无法准确有效地测量其黏度。基于水合物浆黏度理论计算和实验测量方法,通过分析黏度计测量原理,指出对于任一实验系统,其扭矩和黏度存在线性比例关系,因此通过标定标准的扭矩-黏度关系,在实验过程中使用扭矩仪测量扭矩值,即可根据线性关系得到水合物浆的黏度。进一步设计了实验方案,采用4种常用的预测模型作为理论模型,将测量结果与理论计算结果进行了对比验证。结果表明:该方法操作简单,可以快速、准确地测量水合物浆黏度。(图2,表3,参10)Conventional viscosity measurement instruments cannot guarantee the high-pressure and low-temperature conditions for the stable existence of hydrate slurry, resulting in failure of accurate and effective measurement of viscosity of hydrate slurry. This paper presents the theoretical calculation and experimental measurement methods of hydrate slurry viscosity and analyzes the measurement principle of viscometer. It points out that there is a linearly proportion relationship between torque and viscosity for any experimental system. So, through calibrating standard torque-viscosity relationship, torque meter can be used to read torque during experiment and then the viscosity of hydrate slurry can be obtained according to the linear relationship. Moreover, experimental scheme is designed to use three prediction models proposed in literatures as theoretical models and then the measured results are compared with the theoretical calculation results. The results show that this method is simple and can realize quick and accurate measurement on the viscosity of hydrate slurry.（2 Figures, 3 Tables, 10 References）
