China Gas Information
Has the nation which just finished geological survey revealed work conference, preliminary estimates China's shale gas recoverable resources in 31 trillion cubic meters, and conventional gas quite.
The xinhua news agency reports that our country has to speed up the development of shale gas the favorable conditions, if the measure is proper, can greatly shorten the shale gas development and utilization in China development process, and realize the great-leap-forward development. Shale gas as quickly as possible scale development, will help reduce oil and gas resources shortage in our country, the current situation of even change the energy structure.
Shale gas, is the state department recently approved for the new independent minerals. It is hosted by rich organic matter mud and sandwich in shale, is based on the adsorption and the free state as the main way of existence as a kind of abnormal gas, ingredients to methane is given priority to, is a clean and efficient energy resources and chemical raw materials.
The ministry of land and resources oil and gas to 2020, shale gas center more than 100 billion cubic meters will yield, and 2011 years of conventional gas production (99.8 billion cubic meters) quite. To 2030, production and conventional gas is expected to be quite, and close to the United States.
Enterprise would have WenFengErDong, in international oil prices under the situation of unconventional natural gas seriously.
February 10,, the oil in the institution of China petroleum and natural gas exploration and development of the acquisition of royal Dutch shell, British Columbia, Canada west Groundbirch block assets 20% rights and participate in the downstream LNG project was approved by the national development and reform commission factory cooperation.
Previous January 5,, sinopec group announced $2.2 billion purchase price in German companies in the us Nebraska endure eritrea, Nebraska, Mississippi, especially to Ohio, especially's card's card, Michigan and tower kalou shale oil and gas assets, five of the rights of a third. At the same time, cnooc also and sinopec HuaDongJu joined in shale gas exploration.
But with the U.S. shale gas mining decades of experience in China than in shale gas mining has just started, including technology, management system, all at groping stage.
Shale gas prospect is infinite
In 2011, China's natural gas external dependence in reaching 24.3%. The Chinese government has been pushing energy diversification, including shale gas and coalbed methane as a major unconventional natural gas is ready to chase after hold in both hands.
Xiamen university, director of the institute of China's energy economy LinBoJiang says, shale gas production if able in 2020 to 100 billion cubic meters, can really improving domestic energy structure. But hongfa oil company technology researchers said: "the outlook is good, and the specific will have to see the actual policy is proper, also need to the test of time."
The United States from the 1970 s, is in a shale gas research. The horizontal well with the key technologies, such as a breakthrough, its development costs down. In the late 1990 s, shale gas in the United States to take the lead to achieve the commercialization, scale. In 2010 the United States shale gas production more than 137.9 billion cubic meters, which accounts for 23% of the national total output in natural gas.
Lack of core technology
"Shale gas reserves and the data is there is a lot of version, each data are the basis, but all are not the most accurate." Anton oil shale gas development department general manager said.
says, the current domestic oil enterprise are not master the size of shale gas mining core technologies, is through the introduction and the foreign enterprise cooperation way.
However, the state council development research center in the ZhangYongWei researchers in a paper said China in the drill, fracturing, underground train equipment manufacturing equipment, etc, and we have strong technology and production capacity, the domestic company's drilling equipment has been exported to the United States, used for shale gas development. At present the main in the system and complete set technology of some single supporting technology gap equipment.
On the other hand, think, domestic and foreign shale gas shale gas phase of product has a difference, the domestic shale gas is still under development groping stage, even if introduce technology, also need time to digest, localization.
"The enterprises purchase introduce foreign shale gas mining project, estimate is accumulating experience and technology." said, introduce the domestic enterprises in three shale gas resources also many, "but in the short run, domestic shale gas mining is still in the experimental stage, the output is difficult to promote quickly."
