1. 21 centuries are the century of natural gas, natural gas is high grade fuel and industrial chemicals. As fuel, its combustion is complete, unit hair quantity of heat is big, the child after combustion is small to environmental influence; As industrial chemicals, it is clean, qualitative actor, cost is low, can produce products of a variety of careful chemical industry and product of high additional cost with it, the above character of natural gas is the reason that it favors by the user. The proportion that natural gas holds in structure of world energy resources rises ceaselessly, was 1970 according to statistic 17.7% , was 1980 18.8% , was 1990 21.5% , was 2000 22.3% , predict to was 2010 24.3% .
Experience of 19 centuries coal exceeds Chai Xincheng 100 years to be the first the sources of energy; Experience of 20 centuries oil exceeds coal 60 years; Natural gas will come to exceeded oil to become the first the sources of energy 2020 2010 with 40 years. Recoverable reserves of global natural gas now oneself amount to 145 trillion stere, crop of item the year before last year is 2.2-2.3 about -727379968 stere, store collect than be as high as 65, substantial natural resources laid solid foundation for the development of natural gas industry; At present what two big trends are promoting natural gas consumption increase. It is each country government above all the coal of the sources of energy that to protect an environment to be in abundantly replaces a tradition with natural gas and oil; It is to developing the applied field with new natural gas next (if serve as a car,use fuel) . Already grew 25% to the consumption that 10 years culmination enraged like that 1997 1987 from this, and oil is tasted for 15% , coal is 4.5% . Produce the difficulty with area and distant apart of consumptive area situation to overcome natural gas, liquefied natural gas (LNG) oneself the main product in making natural gas international trade, year trade volume is 100 billion stere about, and its price oneself can taste photograph competition with oil. Be built as conduit and store the progress of carry technology, cost transporting gas also is in drop ceaselessly, because of the commerce of this natural gas the volume also is rising, already achieved left and right sides of about 440 billion stere at present, 20% what occupy gross about.
2. Our country is one of countries with resourceful natural gas, reserves of natural gas distant view amounts to 38 trillion stere about, among them onshore occupy 79% , maritime occupy 21% . Although our country has rich natural gas resource, of natural gas use serious however lag, occupy only in structure of the sources of energy about 2% , and industrial developed country is 30-40% commonly. Our country still is in the structure of the sources of energy that gives priority to with coal, develop quickly as national economy, oneself bring a series of serious problems, if the environment is exasperate, traffic is carried can't bear heavy burden, people life quality is not advanced. As a result of our country oily resource oneself the need that cannot satisfy economy to develop, our country oneself become oil to taste entrance country, and import specific gravity rising ceaselessly. Structural adjustment of the sources of energy already extremely urgent, structure of affirmatory the sources of energy will have the state strategical adjust, make coal, oily, angry application scale tends reasonable. Start at present enrage on the west east be defeated by a project is structural adjustment of the sources of energy is prelusive, the use per cent of the natural gas inside a few years will last henceforth apace rises, 2015 around, predict to will achieve 10% above.
