Simulating device for solid-state mining experiment of gas hydrate

Abstract

The invention relates to a gas hydrates solid state exploiting experiment simulation device, which is characterized by comprising a vertical lift pipe, wherein an inlet on the lower end of the lift pipe is connected with a feed bin and extends into the feed bin; an outlet on the upper end of the lift pipe is tangentially connected with the upper part of a cylindrical separator; the bottom of the separator is provided with a turbine flowmeter and a solid state particle weight-measuring device; the turbine flowmeter is connected with a liquid level holding water tank; the solid state particle weight-measuring device is connected with an inlet on the upper end of a particle recovery pipeline; an outlet on the lower end of the particle recovery pipeline is connected with the feed bin; the bottom of the liquid level holding water tank is connected with the bottom of the feed bin through a pipeline; a vertical section of the lift pipe is provided with a plurality of gas injection pipelines; each gas injection pipeline is provided with a plurality of gas injection ports communicated with the lift pipe; the gas injection ports are connected in parallel with a gas transmission pipeline through the gas injection pipelines; and the gas transmission pipeline is connected with an air compressor through a rotermeter and a gas-pressure regulator. The device has the advantages of simple structure, convenient operation, accurate simulation and the like, and can be applied to laboratory simulation of a sea seepage type gas hydrates solid state exploiting technology.

Description

technical field [0001] The invention relates to a natural gas exploitation device, in particular to a natural gas hydrate solid-state exploitation experiment simulation device. Background technique [0002] Gas hydrates have been widely found in permafrost zones and seabeds, and their content is estimated at 2000 trillion m 3 About two times the carbon content of known minerals (oil, coal, natural gas) in the world. Natural gas hydrate has the characteristics of wide distribution, large storage scale and high energy density, and is considered to be one of the potential new energy sources in the 21st century. The development and utilization of natural gas hydrate resources has become a top priority for governments in the energy field, especially the research on the production methods of seepage-type natural gas hydrate with high quality, shallow burial and concentrated distribution is the main direction of current research. Natural gas hydrate is mainly stored in the ocean ...
