Energy sector, "newborn"

In China, shale gas is the energy sector, "newborn", in December 2011 was only approved by the State Council as an independent minerals. However, in the international arena, because of  shale gas  reservoir area has long been mined long life, long production cycle and other unique advantages, as an important complement to conventional energy sources. In recent years, the United States launched the "shale gas revolution", it is by virtue of the large-scale commercial shale gas exploitation, the country gradually get rid of dependence on imported energy, took a benign self-sufficiency road. In the 1970s, out of concern for their own oil and gas resources, the U.S. government science and technology research organization and implementation of shale gas projects, want from unconventional energy to find a breakthrough. 1981 first shale gas well fracturing success, marking a major breakthrough in technology barrier. 20 years from 1979-1999, the U.S. shale gas annual net increase of seven times, initially confirmed the great potential of the industry. In the 21st century, with horizontal drilling, hydraulic fracturing large,fracturing proppant repeat fracturing, staged fracturing promote the use of technologies such as the U.S. shale gas industry to really take off into. Shale gas production in 2011 to achieve 172 billion cubic meters, with annual output of 12.2 billion cubic meters compared with 2000, an increase of more than 10 times, accounting for the same year of natural gas output of 1/4 or more. The rapid development of shale gas in the United States reduced the price of gas energy and related social costs, promote the optimization of energy structure adjustment,hydraulic fracturing while promoting environmental protection, accelerate employment and ensure national energy security, played a significant role can not be ignored.
