China's ministry of land and resources on November 1, held a press conference, announced in 2011, the Chinese oil and gas resources dynamic evaluation results. Results show that by the end of the end of 2011, China petroleum geological resource of 93.9 billion tons, a 2007 evaluation of 76.5 billion tons of increased 22.7%; Natural gas geological resource of 54.6 trillion cubic meters, with 2007 evaluation of 35 trillion cubic meters of increased by 55.8%. Oil and gas geological resource growth significantly.
The recoverable resource volume change perspective, China's oil recoverable resource of 24.58 billion tons, a 2007 evaluation of 21.2 billion tons of increased 15.9%; Natural gas recoverable resource of 33.8 trillion cubic meters, with 2007 evaluation of 22 trillion cubic meters of increased by 53.2%.
It is estimated that by 2030, China's total oil production is expected to more than 250 million tons, natural gas output reached 450 billion cubic meters, the oil and gas production more than 600 million tons of oil equivalent. Among them, the unconventional oil and gas production accelerated growth. Conventional oil output of remain over 200 million tons level, unconventional oil output of 3000-50 million tons, annual production of conventional gas can be close to 300 billion cubic meters, unconventional gas an annual production capacity of 150 billion cubic meters, greatly enhance China's oil and gas support capacity.
In recent years, China's energy resources, such as the ratio of dependence on foreign rising year by year. With oil as an example, its external dependence has from the beginning of the present century of 32% to 57%. In order to alleviate oil and gas resources for economic and social development restriction, China in the recent 10 years continuously increase oil and gas exploration and investment.
Total investment from 2002 in to 22.1 billion yuan (RMB, same below) increased to 2011 yuan, increased by 2.2 times. Oil output of 160 million tons by 2002 increased to 2011 tons, by the world's fifth to fourth; Annual production of natural gas from 22.9 billion 10 years ago to 2011 cubic meters in 101.3 billion to cubic meters, the world to sixth. 18.
According to the Chinese ministry of land and resources geological exploration company priests peng salvo introduction, in addition to increasing investment outside, to master in time the Chinese oil and gas resource potential change situation, the ministry of land and resources regularly organizes to choose some areas to develop oil and gas resources dynamic evaluation. Completed in 2010 six ordos basin evaluation results, announce to the society. 2011 years of dynamic evaluation mainly concentrated in the northeast.
The results show that northeast China petroleum geological resource of 22.5 billion tons, the evaluation result is better than the traditional growth 34%, among which shale oil potential is tremendous, Natural gas geology resources growth 127%, among which shale gas geological resources of 5.9 trillion cubic meters, the recoverable resource of 1.7 trillion square meters; Oil shale (a solid combustible organic mineral) geological resources of 594.3 billion tons, up 74%, becoming the important reserve energy.
