Description
technical field [0001] The invention relates to a natural gas hydrate reservoir in-situ property parameter simulation test system and a natural gas hydrate reservoir in-situ property parameter simulation test method based on the system, belonging to the field of natural gas hydrate exploration and exploitation. Background technique [0002] According to expert estimates, the world's total oil reserves range from 270 billion tons to 650 billion tons. According to the consumption rate in the 21st century, in another 50 to 60 years, the world's oil resources will be exhausted. The discovery of natural gas hydrate has brought new hope to mankind in the energy crisis. Gas hydrate (methane hydrate, commonly known as combustible ice) is a potential geological energy source with large reserves and wide distribution. According to the estimates of the International Geological Exploration Organization, the reserves of hydrated methane in the deep sea of the earth are enough to exce...
