[Abstract]Hydrate slurry technique provides a practical method in preventing hydrate blockage and transporting oil-gas-mixture. The
key to this technology is the stability of hydrate slurry,which is influenced by many factors. In this paper,several orthogonal
experiments were designed to analyze the influence of factors in temperature,pressure,water-oil ratio and gas-liquid ratio on
the hydrate slurry stability,and hydrate volume fraction ratio,water phase conversion ratio and hydrate density were taken as
the representative evaluation parameters of the hydrate slurry stability. On the basis of previously-mentioned hydrate formation
experiments,the influences of these four effecting factors on the stability were determined through programming,and then the
experimental conditions were divided into several different patterns. Finally,the future research direction about the hydrate flow
stability was discussed.

天然气水合物浆液技术为水合物防治和油气混输的实现提供了有效手段,而浆液的稳定性是使该技术实现工业应用的关键,其影响因素较多。利用正交实验分析了温度、压力、水油比、气液比对水合物浆液稳定性的影响,并将水合物体积分数、水相转化率、水合物密度作为水合物浆液稳定性的代表评价参数,基于反应釜内水合物的生成实验,通过编程确定了4 种因素对稳定性代表评价参数的影响程度,在此基础上对流动实验工况进行划分,明确了今后水合物浆液稳定流动性实验的研究方向。
