[Abstract]:According to the related properties of natural gas hydrate, several main mining methods of gas hydrate at present are compared and summarized. Based on the existing theory of gas hydrate hydraulic lifting technology, the minimum lifting speed of gas hydrate particles in the gas hydrate hydraulic lifting system is studied. The minimum lifting velocity of natural gas hydrate particles is calculated by using the theory of hydraulic lifting minimum velocity of mainstream particles and combining with the particle properties of natural gas hydrate, and the comparison is made at the same time. The pipe conveying system of hydraulic lifting system is modeled theoretically, and the particle concentration and particle diameter in the pipeline system during the process of gas hydrate transportation are studied and compared. Effect of lifting speed on pressure drop in gas hydrate riser system.
