摘　　要：根据天然气水合物的相关性质,对比总结了现阶段天然气水合物的几种主流开采方法;在现有的天然气水合物水力提升工艺的理论基础上,研究了天然气水合物水力提升系统中天然气水合物颗粒的最小提升速度;采用主流颗粒水力提升最小速度计算理论,并结合天然气水合物颗粒性质计算出天然气水合物颗粒最小提升速度,同时进行了对比;对水力提升系统的管路输送系统进行了理论建模,研究对比得到了天然气水合物输送过程中管路系统中颗粒浓度、颗粒直径、提升速度对天然气水合物提升管路系统中压降的影响。According to the correlation properties of natural gas hydrate, several main methods of exploi- tation of natural gas hydrate are compared and summarized. Based on the current theory on hydraulic lift- ing process of the natural gas hydrate, the minimum lifting speed of the natural gas hydrate particles is studied, and the minimum velocity was calculated by using the theory of the minimum velocity of hydrau- lic lifting with the natural gas hydrate particles. The theoretical modeling of the pipeline transportation system of the hydraulic lifting system is carried out, and used to study the effects of particle size. The particle diameter is studied, and compared with that on the pressure drop of gas hydrate in the pipeline system.
