According to the news from Observer.com on November 25, good news came from the southern waters of China. It took five years for China's largest high-temperature and high-pressure gas field, Dongfang 13-2, to successfully put into production. This is also a major breakthrough in China's gas field exploration and development technology.
China’s marine power
my country is one of the few countries in the world that has systematically mastered gas field exploration and development technology. China has successfully built my country’s first high-temperature and high-pressure gas field since 2015, which also means that China has formed a systematic high-temperature and high-pressure gas field Exploration and development technology system. With the advancement of the modernization process, China's maritime power is also an important part of it. In the past 20 years, China National Offshore Oil Corporation (CNOOC) has successively overcome world technical problems in many fields such as high pressure and high temperature in the western South China Sea oil fields, laying a solid foundation for China's marine power plan. With the development of China's offshore oil industry technology in recent years, China will also further develop and promote oilfield construction projects to make greater contributions to the transformation of China's energy structure and economic upgrading and transformation.
China's oil and gas exploration and development process
It is understood that the Dongfang 13-2 gas field is located in the Yingqiong Basin in the South China Sea. CNOOC put into production in the stratum about 2,000 meters deep in the 1990s. At a depth of more than 3,000 meters in this formation, it is extremely difficult to conduct exploration and development of oil and gas. It is also because of the lack of technology and funds. China has introduced nearly 6 oil companies from Western countries to explore here, and the exploration has continued for 20 years. After spending 5 billion yuan in 2005, there was still nothing and no commercial value was found.
Many countries have given up. Oil and gas exploration in the South China Sea has thus become a recognized world-class problem. However, CNOOC did not give up because of this, and made great efforts for the long-term development of the country.
Since then, the Western South China Sea oilfields have started their tackling plan based on major national scientific research. After 10 years of hard work, a major breakthrough was finally made and the theory of natural gas accumulation in the area of high temperature and high pressure in the Yingqiong Basin was established. This theory refreshed the previous theoretical understanding and made it clear that the region can be freed and formed on a large scale Since then, the Chinese team has also conducted more than 20 years of technical research and experiments on the basis of this, and continuously overcomes the world’s problems in drilling technology, and subsequently discovered two gas fields, Dongfang 13-1 and 13-2. It is understood that this technology was awarded the first prize of National Science and Technology Progress Award in 2017, and now this technology has been widely used worldwide.
The future construction and development of the South China Sea Atmospheric Region
The successful production of the Dongfang 13-2 gas field is also one of the great achievements China has made over the years. The gas field started construction in 2015 and completed its construction in 5 years. The person in charge of related development said that the peak annual output of the gas field can exceed 3 billion cubic meters, and the annual output alone can provide 1 million people for use for about 15 years. This high-volume production has also driven the development and reform of China's industry. This time the oilfield also adopted China's most advanced drilling technology system, and built two production platforms with various methods such as the integration of key equipment localization. The complexity and scale of the process is also the largest in recent years. China's technological and equipment innovations have also made China's South China Sea atmospheric area more solid. CNOOC also stated that it will continue to use existing theories and technologies to further increase the development of natural gas resources in the South China Sea to further meet the gas demand for industry and people's livelihood in South China.
The implementation of China’s maritime power has also led to the optimization and transformation of China’s various industries, and China’s technological means have continued to make breakthroughs to comply with the progress of energy development and exploration. China has gone from a backward technological approach in the last century to today's global leader. After passing through layers of obstacles and difficulties, China once again proved China's scientific and technological progress with practical actions. It is believed that with the development of China's industry, China's demand for natural gas and other resources will continue to increase, and it is believed that China will also start a new round of exploration in the construction of oil fields.
