China Gas Information
"Shale gas development has been listed as countries' 1025 'special development planning, focusing on exploration reserve evaluation, technology research preparations, founding industry development foundation, 2015 sure shale gas, strive to 1035' during the annual output reached 20 billion ~ 30 billion" cubic meters." Recently held in xian of Eurasian economic BBS Eurasian 2011 national energy roundtable and enterprise summit meeting, national energy bureau chief of oil and natural gas company HuWeiPing when accepting a reporter to interview revealed shale gas development thought.
As unconventional natural gas, global shale gas resources totaled 456.24 trillion cubic meters of natural gas resources, is the conventional 2 times, has become the window of exploration and development of oil and gas resources. The United States is shale gas exploration and development, and has realized the pioneer of the large-scale development and the key technology of the breakthrough, 2010 shale gas output reached 137.8 billion cubic meters, accounting for 23% of its natural gas production, this will make the United States the largest natural gas from importing countries change as natural gas exporter, will also the natural gas market and international world energy pattern the enormous influence. Outside the us, at present Canada have shale gas commercial development of realization.
China's natural gas reserves relatively less, to meet domestic demand, to speed up the development of unconventional oil and gas resources is imminent. In August, 2009, the ministry of land and resources in chongqing the qijiang count launched the first domestic shale gas resources exploration project; On August 20, 2010, the national energy research shale gas (tests) center was unveiled; In July, China's first will shale gas exploration to the sinopec and henan CBM development of company, in order to promote the shale gas exploration and development. At the same time, the oil, sinopec, cnooc gas exploration in shale are found progress, at present already in shale gas vertical fracturing 15 mouth try gas, and well see gas, this also confirmed that the shale gas resources in China has great potential.
"Through the shale gas resources main distribution area in the preliminary evaluation, the domestic shale development in the formation of the Marine, Cenozoic basins in continental. At present our country determined the shale gas international general test project 5 types of 32, the analysis test project has and the international community, have the shale gas comprehensive experiment ability, and completed the domestic 21 mouth and geological data well testing evaluation Wells." China petroleum exploration and development institute langfang sorting, vice President of the national energy shale gas, research and development (experiment), deputy director of the center she said. According to the analogy method, shale gas forecast in China recoverable resource volume over 30 trillion cubic meters, and conventional natural gas resources in basic quite.
In recent years, shaanxi extend oil (group) the limited liability company in ordos basin in shale gas basin continental research and exploration, and achieved initial results, has carried out the shale gas FuJiOu, 7 exploration Wells, evaluation Wells 12, all see good mouth shale gas display. May 13, 177 the oil well extend the vent, become our country the first successfully ignited a continental shale gas well.
According to extend the oil group chief geologist WangXiang introduced exploration results show that, the shale gas distribution in ordos basin area wide, single thickness, quartz content 28.25%, on average, clay mineral feldspar content 26.7% 41.4%, organic carbon content 1.76% ~ 5.88%. Preliminary estimate ordos basin shale gas mainly southeast of 1.5 billion ~ 18 trillion cubic meters, exploration and development prospects very optimistic. "We plan to deploy 2012 20 mouth, horizontal Wells and vertical Wells mouth, built 20 million cubic meters capacity." WangXiang increase said.
Oil and gas strategy center of land and resources, deputy director of the car long wave in late September 11 th held in chengdu of the oil and gas industry on the BBS that, China is shale gas independent minerals set out to determine the legal status of the main body of investment, encourage DuoZhong into shale gas exploration and development fields.
"The energy industry is the second largest development bank loan industry, unconventional fossil energy development imperative." The state development bank review game ZhangQingMin is director of the state in the Eurasian energy roundtable and enterprise summit conference, development bank support enterprise of independent intellectual property rights technology research and development, through the "going out" unconventional fossil energy to realize international cooperation; Through the financing and RongZhi combined, to provide financing consultation and enterprise financial advisory services.
It is reported, the national energy bureau of land and resources, has been compiled completed the shale gas "1025" development planning, set up the shale gas exploration and development of the key technology research project. The future will further increase the scientific research strength, break through the core technology to build gas development, leading experimental shale to realize industrialization.
"Oil shale gas in extended though fields have achieved breakthrough, but also just opened the shale gas exploration and development, from the prelude of real shale gas industrialization development way is still very far away." WangXiang increase said. Experts think that, as a new energy, shale gas resources unconventional development needs a large number of technology, capital and talents into, to the requirements of the technology is very high. Shale gas development and China is still in the stage of exploration has just started, lack of key technology. So to take introduction and independent innovation, strengthen with key technology process development, gradually formed suitable for our country to the exploration and development characteristics of shale gas core technology system.
