"Combustible ice", experts say for natural gas hydrate or methane hydrate ", is a natural gas and water under high pressure and low temperature conditions in hybrid produced a solid material, looks similar to ice or solid alcohol, ignition can be combustion. "Combustible ice" is abundant and widely distributed, and scientists predict that it is the best alternative to conventional oil and natural gas. On February 15, 2012, the Japanese began in Aichi Prefecture Atsumi Peninsula coast from submarine production "combustible ice", opened the prelude to human exploitation of "combustible ice".
The use of combustible ice human has just taken a small step
Deep in deep in the ocean and land, to date on the "combustible ice reserves and recoverable number of years are estimated, different research institutions and experts to provide the data gap" combustible ice ". In some countries, scientific exploration is carried out in order to find out the reserves, distribution and characteristics, which is the prerequisite and basis for the effective development of "combustible ice" resources.
"Combustible ice" occurs in the ocean of 300 - 3000 meters water depth of the seabed sediment, mainly occurs in slope and island slope and basin sediments or sedimentary rocks. The South China Sea "combustible ice" is hidden in the depth of 3200 - 350 meters range. According to media reports, Japan responsible for the drilling of deep earth "," exploration ship to submarine dipping artificial diamond bit, down to a depth of about 1000 meters underwater through remote control robot to find the optimal drilling location, drill down four about 260 meters to reach formation of combustible ice reserves.
The combustible ice resources on the land are mainly distributed in the high latitude polar permafrost, or the slope and uplift of the continental margin. China is the third country in the world, with an area of 215 square kilometers, which is conducive to the occurrence of combustible ice conditions and resource prospects. On September 25, 2009, a news conference held in the Ministry of land and resources, Ministry of land and resources chief engineer Zhang Hongtao, Ministry of land and resources in November 2008 in the Qilian Mountains (600720, Guba) on the southern margin of the permafrost with (Qinghai Tianjun Muli County town, elevation 406.2 m) successfully drilled methane hydrate; June 2009 continue drilling to obtain valuable physical samples, and the samples of indoor identification, mastering a series of data. This is another major achievement after the methane hydrate was drilled in the northern part of the South China Sea in May 2007. Qinghai Province, methane hydrate reserves accounted for about China's terrestrial methane hydrate reserves 1/4. According to the "combustible ice" one of the project leader, China Coal Geology Bureau of coal geology of Qinghai 105 team captain and chief engineer Huai Jun Wen introduction, Qinghai Muli Coalfield containing combustible ice layer section shallow buried, only 130 - more than 300 meters, which mining flammable ice provide very favorable conditions. The frozen soil layer is thin, only 120 - 80 meters, but also for the future research and development brings great convenience, China's development of combustible ice is expected to make a breakthrough here.
The above shows that identify deep marine or terrestrial depths of combustible ice reserves is no easy task, for commercial exploitation more difficult. Since 1830s, some scholars and countries have been studying the problem of the development of combustible ice. However, so far, it is still in the stage of scientific exploration and trial production. Some experts estimate that the development of the marine and terrestrial combustible ice resources, will be in 30 years and 15 years after the mass start. The importance of the development of combustible ice is that, with the increasing reduction of conventional oil and natural gas reserves, combustible ice will become the best alternative energy and strategic resources.
People say that in the depths of the ocean is a great treasure house, however, so far seabed how many and how much reserves of mineral resources remain to be cognitive, still without the ****** of large-scale development. Early in 1965, the former Soviet Union in the West Siberian permafrost Mysore Ahab methane hydrate reservoir by buck, chemical medicine for the mineral resources development, the Soviet Union to become the world's first successful development of methane hydrate. In 1999 Japan's success in offshore production. In 2011, the Japanese R & D out in sandy bottoms and rocky terrain to walk freely unmanned detection machine and detection of seabed terrain of high performance sound technology. On February 15, 2012, in Japan Aichi Atsumi Peninsula coast of trial mining, to prepare for the 2013 formal mining, when there would be the actual mining, and observed the development of combustible ice to the surrounding environment. If successful, Japan will be the first country in the world to develop combustible ice from the bottom of the sea. In 2006, Canada the "decompression" in land exploitation of combustible ice, if can will "decompression" applied to submarine development and success, then add take general is world first use "decompression" exploitation of combustible ice at the bottom of the sea.
The competition among countries is mainly the competition of resources, especially energy. Published in 2001 American security experts Michael Claire "resource wars: the new landscape of global conflict," a Book prophecy: "is the basic outline of the 21st century geopolitical, countries will of oil, timber, minerals and water this kind of strategic material resources, large-scale competition." Back in the 70s of the 20th century, the former U.S. Secretary of State Henry Kissinger prospect of long-term goal of the United States of America geopolitical said: "who controls the oil, who took control of all countries, who control food, who is in control of the all the people; who control the money, who is in control of the whole world." According to the American Legacy Foundation will be May 31, website of the 2011: American free energy center executive director Alexandra Reidy Byrne, an article entitled "America's free energy: economic recovery" in the foundation in this paper. Since 1973, the United States
