China Gas Information
June 27,, the ministry of land and resources shale gas exploration first held the bidding, the bidding of the assignment of gas exploration in shale block 4, mostly located in guizhou, chongqing, and other cities were chongqing southern guizhou shale gas exploration, sichuan guizhou suijiang shale gas exploration, guizhou Yang shale gas exploration, chongqing nongdagaoyou qian shale gas exploration, xiang mountain area of 1.1 square kilometers.
The tender invitation for bid are getting positive response, enterprise of China petroleum and natural gas Co., LTD, China petroleum chemical industry Co., LTD, cnooc (China) the limited company, the yanchang oilfield administration bureau, China united coalbed methane Co., LTD, henan CBM development Co., LTD. To the use of the qualification of the company took part in the activities, and the bidding are bidding on the block bid.
Concerned personage points out, the bidding is not only the management system of the oil and gas resources in China, also sounded the innovation try in accelerating China's shale gas development and utilization, the rally.
It is the future of energy "main force"
Shale gas is from page mined from rock formations, ingredients to methane gas is given priority to, is a kind of important unconventional natural gas resources. Shale gas formation and accumulation has its unique features, often distribution in the basins in large thickness, wide distribution shale formation in hydrocarbon source rocks. More routine, shale gas reservoir compared with natural gas since classifies characteristics, shale is born hydrocarbon source rocks, reservoir, and not by structural control, no trap, no clear gas water interface. Shale gas buried depth range, buried deep from 200 meters to deep in 3000 m. Most of the gas production shale distribution range, thickness, and generally contain shale gas, this makes gas well for a long time to to stable gas production rate, with long service life and mining production cycle long advantages.
Global shale gas resources are very rich. According to the forecast, the world shale gas mainly for 456 trillion cubic meters, the main distribution in North America, central Asia and China, the Middle East and north Africa, Latin America, the former Soviet union and other regions. And the conventional gas quite, shale gas resource potential may be greater than conventional gas.
In recent years, along with the social demand for clean energy is expanding constantly, natural gas prices continue to rise, people to improve the understanding of the shale gas quickly. Especially of horizontal Wells and fracturing technology progress of mankind for the level of shale gas exploration and development are forming boom.
It changed the world energy pattern
The world of gas resources research and shale of exploration and development began in the United States the earliest. Depend on the development of the mature production technology and perfect network facilities, the U.S. shale gas costs only slightly higher than conventional gas, it makes the U.S. to become the world's only realize shale gas large-scale commercial mining country. Data showed that in 2010, the United States shale gas production has more than 100 billion cubic meters. In the past five years, the U.S. shale gas output growth of more than 20 times--from 2006 for its natural gas output only to 1% in 2010 and up to 20% of the total U.S. natural gas. Concerned expert points out, rely on shale gas utilization in the next 10 years, the United States can not only a change in the situation of natural gas imports, to achieve full self-sufficiency, also is expected to become liquefied natural gas exporter.
The United States shale gas revolution has moved the world of liquefied natural gas (LNG), and the market will also be more significant influence, and change the world energy pattern. Thanks to unconventional natural gas especially shale gas development technology breakthrough, in 2009 the United States to 624 billion cubic meters of yield more than Russia for the first time as the world's natural gas producers. Production status in the replacement of the natural gas consumption long-term dependence on imported situation turning. American experts excited to think that with shale gas, 100 in the United States do not have trouble back at home.
Shale gas development, especially the United States shale gas production, the rapid increase of the most people are still very strange energy a hot topic. Sadly shale gas revolution "of the" global natural gas supply and demand and began to change and price trend, a major impact and cause a natural gas production and consumption power attention. Shale gas utilization become a low carbon economy strategic development opportunity, the driving force to become the world's oil and gas geopolitical pattern structural adjustment of catalysts.

Our country has DuoDa potential
Our country is rich in shale gas resources. According to the present, our country shale gas exploration recoverable resource volume of about 26 trillion cubic meters, resource potential and the United States, and the different similar is, our country's shale gas mining more difficult, shale gas depth than in the United States more deep. Russia some experts believe that Chinese shale gas development is still in the "young" stage. Americans also think, technically speaking shale gas development in China is still in the early stages.
But our country strong demand for natural gas, driving the shale gas industry to accelerate development. In 2009, China's natural gas consumption of 81 billion cubic meters, which is 76 billion cubic meters per domestic production, accounting for 94%. It is estimated that by 2020, China's natural gas gap will break 135 billion cubic meters. Therefore, actively develop non-conventional gas resources in a planned way to meet the demand for gas in China is an important and security.
In order to speed up the development and utilization of the shale gas, the national development and reform commission and national energy bureau in starting in September of 2009, the researchers developed a encourage shale gas exploration and exploitation of policy. National energy board recently set up shale gas exploration and development of the key technology research project, increase science and technology research efforts, break through the core technology in our country, in order to speed up the pace of shale gas exploration and development. Shale gas special development planning and related policy is compiling the and research.
This April 13, land and resources by oil and gas resources center for strategic studies organization of the implementation of the "national shale gas resource potential evaluation and favorable to the optimization of the first special" a well deep super km strategy survey a well-cen page 1 Wells, 岑鞏 county in guizhou province sheep Bridges smooth spud.
Oil and gas resources of land and resources, deputy director of the center for strategic studies ZhangDaWei said, China's shale gas resources strategy survey and exploration and development of strategic objectives are, to 2020 in the selected and 50 to 80 target zone and 20 favorable to 30 shale gas exploration development zone, recoverable reserves, the stable growth reached 1 trillion cubic meters, shale gas production, achieve the fast growth of the conventional natural gas production by 8% to 12%, make shale gas has become China's important clean energy resources.
ZhangDaWei Suggestions, our country should adopt the American development experience, shale gas development need to break the monopoly and innovation the mining right management system; Encourage shale gas resources for strategic research and exploration and development policies; With reference to the development of domestic coalbed methane exploration, the preferential policy to give shale gas and domestic development of coalbed methane exploration as preferential policies; Shale gas development of key equipment shall be exempted from VAT and customs, import of shale gas mining give norm subsidy, the key technology research and development and application give preferential, guide and promote shale gas industrialization.
