　　Chen Chuanhong, director of the Major Special Office of the Ministry of Science and Technology, presided over the press conference, introduced the overall progress of major national science and technology projects, and pointed out that as an important starting point for implementing the innovation-driven development strategy, the oil and gas development project produced a number of major landmark achievements in the organization and implementation process, and achieved remarkable economic and social benefits, which opened up a new industrial development direction in the oil and gas energy field, effectively supported the national energy security, and significantly improved the upstream scientific and technological innovation capability of the petroleum industry.

　　Li Fanrong, deputy director of the National Energy Administration, introduced the overall implementation progress of the oil and gas development project. Oil and gas development project is the only major national science and technology project organized and implemented by enterprises. Under the leadership of the CPC Central Committee and the State Council, and under the organization and coordination of the National Development and Reform Commission, the Ministry of Science and Technology and the Ministry of Finance, we will adhere to the innovation-driven strategy, practice the scientific and technological research mode with enterprises as the main body and Industry-University-Research as the combination, gather the superior forces of the whole society for collaborative innovation, strengthen the combination of projects and demonstration projects, and comprehensively complete the overall goals and tasks of the Eleventh Five-Year Plan and the Twelfth Five-Year Plan. The three ministries and industry experts spoke highly of the organization, management and implementation of the special project.

　　Since the implementation of the special project, significant progress has been made in six major areas, including onshore oil and gas exploration, onshore oil and gas development, engineering technology, offshore oil and gas exploration and development, overseas oil and gas exploration and development and unconventional oil and gas exploration and development, with remarkable results.

　　First, six major technical series and 20 key technologies have been formed, 13 major equipment have been developed and 22 demonstration projects have been built, and China’s oil and gas exploration and development has entered a new era of innovation and development.

　　The second is to ensure that China’s oil production is rising steadily and natural gas production is developing by leaps and bounds. The output of crude oil increased steadily from 185 million tons in 2007 to 198 million tons in 2016, and remained the fifth largest oil producer. Natural gas production rose rapidly from 67.7 billion cubic meters in 2007 to 137.1 billion cubic meters in 2016, making it the sixth largest gas producer in the world.

　　Third, it has promoted the construction of national innovation system and enhanced China’s oil and gas independent innovation capability. It has formed a high-level R&D team with 100 enterprises covering the upstream technology of the petroleum industry, more than 50 universities of the Ministry of Education and more than 20 research institutes of the Chinese Academy of Sciences. Construction of 9 national, 23 provincial key laboratories and R&D centers and other high-level innovation platforms. Related achievements won 3 national special prizes for scientific and technological progress, 5 first prizes and 19 second prizes, applied for 2,143 invention patents, formulated 185 national and industry standards, and registered 722 software copyrights.

　　Academician Jia Chengzao, the chief technical engineer, mainly introduced the great progress in the exploration and development technology of marine and deep natural gas in China. Through special research, China has made substantial breakthroughs in marine and deep natural gas exploration and development technology, discovered and built a number of large gas fields, realized the leap-forward development of natural gas production, guaranteed national energy security, and promoted social and economic development and the construction of beautiful China.

　　First, a series of international advanced natural gas exploration and development technologies have been formed, and a number of large gas fields have been discovered and built.

　　First, innovative development of major technologies for marine carbonate oil and gas exploration and development, the discovery and construction of Anyue super-large gas field with the oldest geological age, Yuanba deep reef gas field and Puguang high-sulfur gas field in Sichuan Basin, and the growth of carbonate natural gas reserves in Tarim and Ordos basins.

　　Second, the development of deep natural gas accumulation theory and exploration and development technology in foreland thrust belt, especially the conquest of major exploration technologies such as deep-seated wide-line large-scale seismic acquisition and prestack depth migration in complex mountainous areas, has expanded the depth of natural gas exploration and development in Kuqa thrust belt to 8,000 meters, and found six large gas fields with a production capacity of 26 billion cubic meters under extremely thick saline strata, ensuring the safe and stable gas supply of "West-to-East Gas Transmission".

　　Third, major breakthroughs have been made in exploration and development technologies of unconventional natural gas such as tight sandstone gas and shale gas, and unconventional natural gas has become an important part of China’s natural gas production. For example, breakthroughs have been made in key technologies such as tight sandstone gas accumulation theory and reservoir fracturing reconstruction, which has realized the effective development of Sulige large tight sandstone gas field, with an output of 22 billion cubic meters in 2016; Technologies such as multi-stage fracturing and industrial development of horizontal wells have supported the effective development of shale gas fields such as Fuling and Changning-Weiyuan, with an output of 7.8 billion cubic meters in 2016.

　　Fourth, China has made great progress in key technologies and equipment for offshore deep-water exploration and development, discovered large gas fields such as Lingshui 17-2, and successfully developed the first deep-water gas field in the South China Sea — Liwan 3-1.

　　Since the implementation of the special project, China’s natural gas industry has achieved leap-forward development, and the accumulated proven geological reserves have doubled, from 6.1 trillion cubic meters at the end of 2007 to 12.98 trillion cubic meters in 2016, and the world ranking has risen from 14th to 9th. The annual output of natural gas in China has doubled, from 67.7 billion cubic meters in 2007 to 137.1 billion cubic meters in 2016, and the world ranking has risen from ninth to sixth. The proportion of natural gas in the primary energy consumption structure increased from 3% to 6%, and increased to 8.3 ~ 10% at the end of the 13th Five-Year Plan. Make great contributions to China’s energy structure optimization and environmental improvement.

　　In addition, the exploration and development of offshore deep-water natural gas in China has made great contributions to safeguarding China’s maritime rights and interests and implementing the national marine strategy; It has cultivated new industries such as the development of unconventional natural gas resources such as shale gas and coalbed methane in China, such as the development of marine shale gas in the south, which has guaranteed the gas consumption of local industries and residents and promoted the development of local economy; The large-scale development of coalbed methane has become an important clean energy in Shanxi Province, and has made important contributions to the development of low-carbon and green economy.

　　During the "Thirteenth Five-Year Plan" period, we will further strengthen the theoretical and technical research on natural gas exploration and development, constantly overcome the bottleneck technologies of deep-seated onshore, deep-water offshore and unconventional natural gas exploration and development, provide technical support for ensuring the steady growth of national natural gas reserves and production, and promote the further optimization of national energy structure and the sustained and stable development of national economy.
