According to xinhua news agency said, after more than 10 years of technical research, jilin university scientific research team developed a cold gas hydrates drilling thermal recovery key technology for land, in the international leading level.

Natural gas hydrate, also called combustible ice, distributed in deep-sea sediments of the permafrost of the land or, is formed by water and natural gas in high pressure under the condition of low temperature of the ice crystal material, after combustion generates only a small amount of carbon dioxide and water, pollution is a lot less than coal, oil, natural gas, but ten times higher than that of energy.

Combustible ice huge reserves, including total organic carbon resource is equivalent to two of the world's known coal, oil and natural gas, is internationally recognized as oil, natural gas energy.

Jilin university since 2004, to research and develop the combustible ice drilling project for land to conquer the high altitude and cold region construction and so on many technical problems, successfully developed the first at home and abroad with independent intellectual property rights of the hydrate cold thermal recovery key technology.

With general international "passive pressure insulation sampling drilling principle, new technology for the first time put forward" active cooling refrigeration sampling ", invented the drilling mud improved hole bottom cooling method, the hydrate rapid freezing sampling method and the high temperature heat pulse excitation mining technology, the main technical indicators are more than similar foreign technology.

At an altitude of 4000 meters of yushania basin in qinghai province, the scientific research team for the first time to use the technology to drill for the land natural gas hydrate samples in our country, and successfully realized the land natural gas hydrate exploitation, breaking the monopoly of foreign hydrates drilling sampling technique.

Recently, the technology won the national prize for technical invention in 2016.
