Why do most of the "combustible ice" stored on the seabed attract the big countries in the world to compete in its mining methods? The main reason is that "combustible ice" has made humans increase a lot of energy sources, if it can be low cost and high security. The commercial development of the land is basically no need to carry out complicated chemical treatment in the later stage. Compared with crude oil/coal, it needs to be cracked. Many refineries need to be environmentally friendly and save money, and the pollution to the environment after combustion is very small.
However, almost as with the previous major scientific and technological breakthroughs issued by the previous countries, this news came out and attracted the voices of all parties.
One type of voice believes that "from science to technological innovation must go through four stages of knowing (discovering phenomena), knowing why (theoretical understanding), making things (technically feasible), and liqiran (economically viable). The significance of this breakthrough in China is to make use of 'combustible ice' to achieve the stage of 'making it'."
"This time China made a breakthrough because it turned the mining solid into a gas, released the methane in the hydrate by depressurization in situ, and directly extracted methane. At the same time, the whole process remained controllable and did not cause the seabed. Methane leaks."
"The exploitation of 'combustible ice' is very laborious. It is deeply buried in the seabed environment of high pressure and low temperature. If it is not careful, it will easily cause submarine landslide. Japan will study the mining technology before China, but it can't solve the problem of silt blockage, 'combustible Ice's mining has not made progress. Although China is not the first country to find 'combustible ice', it is not the first to produce 'combustible ice', but we dare to claim to be the world's number one because 'Stable mining' these four words."
Of course, there is another type of voice: “The drilling technology used in this time, the 'combustible ice' mining technology and the drilling ship are conventional technologies and equipment. This technology and equipment developed by conventional oil and gas exploration to exploit the “flammable ice†All the major oil companies in the world will do it."
“If there is a large area of ​​methane gas spilling out of the sea floor, it will be an ecological disaster...â€
"What kind of technology can cover the methane gas that overflows after the melting of 'combustible ice' under the sea floor without spilling over the sea floor? There is no world at present, and China does not!"
In addition, in the report on "combustible ice", an oolong such as "50,000 km" was also raised. Regrettably, the oolong in this report has contributed to the paradox of another direction: I think that China’s trials are completely meaningless, even self-deception.
Regardless of whether "combustible ice" is "yang" or "suppress", as a portal for scientific instruments and analytical testing, we are more concerned with the detection technology of "combustible ice".
It is understood that deep-sea combustible ice detection has made a great breakthrough in technology, but there are still expensive (for example, "deep sea methane in-situ detection system" its cable-controlled robot price is more than 40 million yuan / Taiwan), the whole set of detection The device is very complex, has limited detection capabilities, and is difficult to adapt to the detection of the characteristics of the flammable ice distribution.
However, there are already technical experts who are working on the development of a new type of deep-sea combustible ice detection system, including an elderly person who is over 70 years old, and the technical leader of Hefei Aox Optoelectronics Technology Co., Ltd., Professor Ding Houben. Ding Houben has been engaged in national defense science and technology since 1963; from 1986 to 1991, he served as dean of the School of Engineering of the Nuclear Ninth Institute; in July 1991, he worked as a high-tech talent introduced in Anhui to work in Anhui Hefei.
He led the development of a deep-sea combustible ice detection system designed to provide a deep-sea combustible ice detector based on gamma-ray Compton backscatter scanning technology. According to the relevant materials of the company, it can directly, quickly, safely and accurately determine whether it is flammable ice; and the equipment production cost is low, the device structure is simple and easy to operate. This project won the first prize in the first Sichuan Science and Technology Workers Innovation and Entrepreneurship Competition in 2016.
According to relevant information, in 2011, China has set up 25 “combustible ice†metallogenic blocks in the South China Sea, with a controlled resource of 4.1 billion tons of oil equivalent. If a block requires 30 sets of deep-sea combustible ice detectors, a total of 750 sets of detectors are required. The price of each set of detectors is conservatively estimated at 2 million yuan, 750 sets are 1.5 billion yuan, and there are more ore-forming blocks. Waiting to be discovered. Therefore, the development of new "flammable ice" detection technology also has potential commercial value.
