It is learned that Lingshui 17-2 is China's first 1,500m deep water gas field run by Chinese entities, with a proved geographical reserve of more than 100 billion cubic meters, and being 150km away from Hainan Island. As introduced by Yu Yi, board chairman of Offshore Oil Engineering Co., Ltd., after the gas field is put into production, it will stably supply 3 billion cubic meters of gas for Guangdong, Hong Kong, Hainan and other places each year, and can meet one quarter of the domestic demand for gas in the Greater Bay Area. At the same time, the gas field facility of the "Deep Sea One" energy station may drive the development of the nearby medium-scale gas fields such as Lingshui 18-1 and Lingshui 25-1, so that a gas field cluster may form. Relying on the existing natural gas pipeline connecting Guangdong-Hong Kong-Macao Greater Bay Area and Hainan Free Trade Port, a large gas field zone of 1,000 billion cubic meters will be built in South China Sea to develop, produce and transmit natural gas resources to the greatest extent and to make greater contribution to the construction of a country with strong maritime power and the national energy security.
