Abstract

The invention discloses a system for storing and transporting natural gas based on a hydrate method and a use method of the system, relates to the field of natural gas storage and transportation, andparticularly relates to a system for storing and transporting the natural gas based on the hydrate method and the use method of the system. Specifically the system is a system for carrying out hydratesynthesis, storage and decomposition reutilization on the natural gas by the hydrate method. The system comprises a hydrate slurry synthesis system, a low-temperature hydrate generation system, a transmission system, a hydrate underground low-temperature storage reservoir and a hydrate decomposition system. According to the system, natural gas and configuration water are used for synthesize hydrate slurry through the mode comprising stepped distribution of gas injection ports, pressure-fluctuation-type injection of the natural gas, and forward and reverse vortex-type stirring; and the hydrateslurry and the natural generate a natural gas hydrate through spraying. The preparation method provided by the invention simple, the processes are few, and the problem of blockage in a water circulation loop is solved, so that the natural gas can be stored and transported in a solid form, and the storage and transportation mode is more flexible and convenient.

Description

technical field [0001] The invention relates to the field of natural gas storage and transportation, in particular to a system for storing and transporting natural gas based on a hydrate method and a method for using it, in particular to a system for hydrate synthesis, storage, decomposition and reuse of natural gas through the hydrate method. Background technique [0002] The huge resource potential of natural gas hydrate has attracted widespread attention in the oil and gas industry.
