A three-dimensional constant overburden pressure model for high-efficiency simulation of natural gas hydrate

Abstract

The invention relates to a three-dimensional constant overburden pressure high-efficiency simulated natural gas hydrate model, comprising a simulated support, the simulated support including a pair of support blocks distributed up and down; a pressure simulation container placed in the gap between the two support blocks, The pressure simulation container includes a pressure container body; a hydrate simulation container placed in the pressure simulation container, the hydrate simulation container is driven into and out of the pressure container body by a feeding mechanism, and also has a monohydrate in the pressure container body. Simulates a container gripping mechanism. The advantage of the present invention is that: by adding a pressure simulation container outside the hydrate simulation container, when the hydrate simulation container is deformed, the pressure in the pressure simulation container can be changed to prevent the hydrate simulation container from being deformed. By making the hydrate simulation container thinner as a whole, the weight of the corresponding hydrate simulation container becomes lighter, which is convenient for experiments.

Description

Technical field [0001] The present invention relates to the field of natural gas development, and more particularly to a three-dimensional hemorrhable high-efficiency simulation of natural gas hydrate model. Background technique [0002] Natural gas hydrates are also known as "flammable ice", which is distributed in permanent frozen soil distributed in deep sediments or land, which is formed by natural gas and water in high pressure low temperature conditions. Because of its appearance, it can be combusted as ice, it is called "flammable ice". Its resource density is high, the global distribution is wide, and it has a high resource value, which has become a long-term research hotspot in the oil and gas industry. Since the 1960s, some countries represented by the United States, Japan, Germany, my country, South Korea, and India have developed a research plan for natural gas hydrate exploration and development. So far, there have been more than 230 hydrate mines in the sea seas and...

Problems solved by technology

[0005] At present, the existing hydrate development stratification physical simulation container, when simulating the distribution of the hydrate layer in the underground, simulates problems such as high pressure and pressure changes in the container. Therefore, in order to avoid affecting the hydrate layer in the container Generally, the wall thickness of the container is generally thickened, which leads to a large volume, heavy weight, and inconvenient movement of the overall container, which is not conducive to the experiment.
