| 摘 要： | 水合物浆液的黏度及非牛顿特性是水合物流动安全保障的重要参数，其研究对于水合物风险控制技术以及深水油气管线输送的安全预警具有重要的意义。本文介绍了用于水合物生成、黏度及非牛顿特性研究的流变仪类型以及在流变仪内进行水合物生成的实验材料；总结了水合物生成影响因素对水合物生成过程中黏度的影响规律，梳理分析了水合物浆液黏度定量表征模型；从剪切稀释性、触变性、屈服特性以及黏弹性4个方面总结了水合物浆液非牛顿特性的研究成果。总体而言，水合物浆液黏度及非牛顿特性研究存在较强的体系依赖性，构建的水合物浆液黏度模型所考虑的因素各异、普适性不高。最后，本文给出了今后在流变仪内开展水合物实验及模型研究的方向和建议：水合物微观结构参数和浆液流变参数的耦合研究；综合考虑水合物浆液非牛顿特性的黏度预测模型；水合物浆液黏度及非牛顿特性和水合物堵管理论的结合。 |

| Abstract: | The viscosity and non-Newtonian properties of hydrate slurry are important parameters for hydrate flow assurance, the research of which is of great significance for the hydrate risk control technology and the safety warning of deep-water petroleum transportation. In this paper, different types of rheometer and non-Newtonian properties were introduced. Additionally, impacts of the influence factors on hydrate slurry viscosity were summarized and the quantitative characterization models of hydrate slurry viscosity were analyzed. The research results of non-Newtonian characteristics of hydrate slurry were reviewed from four aspects including shear shinning, thixotropy, yield stress and viscoelasticity. Generally, there was a strong system dependence on the viscous slurry viscosity and non-Newtonian characteristics. The established hydrate slurry viscosity models considered different kinds of factors and had lower universality. Finally, the future research directions for hydrate experiments and model study in the rheometers were proposed: coupling study on parameters between hydrate micro-structure and slurry rheology, viscosity model considering the non-Newtonian characteristics of hydrate slurry, combination of the viscosity and non-Newtonian properties of hydrate slurry and hydrate plugging theory. |
