Although shale gas is becoming a bright spot in the primary energy structure, it also brings hope to lower oil and gas prices in the world oil market, lower production and living costs, and promote economic recovery. But shale gas is not renewable energy, even if it can A considerable period of supplements or even substitutes for oil, but it cannot be the kind of renewable energy that is expected to be acquired by anybody. Just as international oil prices are frequently affected by geopolitical factors and other factors, an unconventional natural gas, shale, is on the rise of high levels. Gas has gradually occupied an important position in the existing energy structure and has become a bright spot in primary energy. The International Energy Agency recently said that global unconventional natural gas will enter a golden period of development. Shale gas is natural gas contained in the shale system. It is composed of coalbed methane and tight sandstone gas, which constitutes three unconventional natural gas. It is a clean new energy resource. According to authoritative data, the world's shale gas resources are 456 trillion cubic meters, which is equivalent to conventional natural gas, mainly distributed in North America, Central Asia, West Asia, North Africa, Latin America and the former Soviet Union. Among them, China and the United States have the highest shale gas extraction capacity in the world. According to the latest estimates, the recoverable amount of shale gas in China is 36 trillion cubic meters, and the United States is 24 trillion cubic meters. However, in terms of actual mining, China is still in its infancy, and after more than a decade of development, the United States has formed a daily production capacity of 900,000 barrels of shale gas, which is expected to reach more than 2 million barrels in 2020. In order to speed up shale gas development and reduce dependence on foreign oil and gas imports, China has included shale gas development in the “Twelfth Five-Year Plan†and proposed that shale gas production will reach 6.5 billion cubic meters per year by 2015. The annual output should reach 60 billion cubic meters to 100 billion cubic meters. At present, this plan is being implemented. After the first public bidding for the shale gas exploration rights in June 2011, the second round of bidding will start in September this year. This shows that China's shale gas development is heating up rapidly, and the curtain of full mining has been opened. Some analysts believe that if China can reach mass production in a relatively short period of time, even with the shale gas production in the United States, the layout of the world's energy structure will change dramatically. Statistics show that the US shale gas production in 2010 was 137.92 billion cubic meters, accounting for 23% of the country's natural gas production, and in 2011 it was close to 180 billion cubic meters (the US oil and gas daily consumption was 18.8 million barrels per day). The shale gas extraction has increased significantly, making the United States increasingly dependent on imported oil. According to the US Energy Information Administration, US foreign dependence on oil has dropped from 60.3% in 2005 to 45% in 2011. In the next decade, the US plans to cut oil imports by another one-third, and by 2020, oil imports will be reduced. Reduced to about 6 million barrels, and reduced to less than 4 million barrels by 2035. By then, the US self-sufficiency rate for energy will reach 87%. According to the International Energy Agency, if the oil price remains high in the future, the development speed of shale gas will inevitably increase. It is estimated that by 2035, the output of unconventional natural gas, mainly shale gas, will reach 1.6 trillion cubic meters, accounting for nearly two-thirds of the increase in natural gas supply over the same period. The share of unconventional natural gas in total natural gas production will be from the current 14% rose to 32% in 2035. Among them, the proportion of shale gas in the United States is expected to reach 43% by 2015 and 60% by 2035. US public opinion even believes that non-traditional energy development, including shale gas, will create 600,000 new jobs for the United States in the second decade of this century. Shale gas mining will not only revitalize the US economy, but also enable the United States. Become a Saudi Arabia in the natural gas industry. However, it is still too early to conclude that shale gas will dominate the energy structure. Because the exploration and exploitation of such unconventional natural gas is subject to fluctuations in international oil prices, it is also expected to break through the new exploration and mining technology, and it is also subject to environmental protection. According to the operating rules of the world oil market, when oil prices remain high, the market is highly motivated to explore oil and gas, because only when the oil price rises, the relevant investment will have a profit return, otherwise no one cares. Exploration and exploitation of shale gas is no exception. If oil prices are low and declining, people would rather consume cheaper oil, in which case shale gas will be lost. Therefore, the industry believes that the exploration and development of shale gas will inevitably face risks from the market and will require strong support from national policies and regulations. In addition, the exploitation of shale gas faces many technical and environmental barriers. At present, the United States uses hydraulic fracturing technology, which requires a large amount of water resources. This is obviously not desirable in the case of global water shortage, which is wasteful and environmentally friendly. Therefore, some countries such as France have clearly denied This mining method. At present, in addition to the United States, Canada, Australia, Germany, France, Sweden, Poland and other countries have begun to invest in shale gas research and exploration and development. However, due to the different geographical locations and topography of the countries, the relevant mining technologies have yet to be developed according to the actual local characteristics. Therefore, shale gas exploration and exploitation in the world still faces major technical challenges. It should be pointed out that although shale gas is becoming a bright spot in the primary energy structure, it also brings hope to lower oil and gas prices in the world oil market, lower production and living costs, and promote economic recovery. But shale gas is not renewable. Energy is still a traditional energy source that is consumed at one time. According to current technical means, shale gas can be used for up to 100 years. It is the same as existing oil and gas, and it will be exhausted even in a comparable period. It supplements and even replaces oil, but it cannot be the kind of renewable energy that can be expected from any production. As experts believe, shale gas will play a transitional role in connecting other fossil fuels such as oil before renewable energy such as wind and solar power matures.
