China Sea Oil says, This proves once again the advanced nature and reliability of the complete set of deep-water oil and gas field drilling and completion technology system, It indicates that China already has the oil and gas exploration and development capability of deep water and super deep water. "Deep Sea No .1" gas field is located 150 kilometers from Hainan Island, Found in 2014 by China oil exploration, Proven natural gas reserves of more than 100 billion cubic meters, The maximum water depth is over 1500 meters, The altitude of Mount Tai, The maximum depth of the well is over 4000 meters, So far, China has found the deepest average water depth and the most difficult exploration and development of the offshore deep water gas field. "Deep Sea No .1 gas field is developed using the" semi-submersible production platform underwater production system "model, A total of 11 development wells were deployed in seven deep-water well areas with an east-west span of more than 50 km, Faced with many challenges, such as large working water depth, large differences in well conditions, frequent extreme weather, There are few successful cases of the same type of operation worldwide. "completion of drilling and completion, Is the key link of gas field production, We found oil and gas from deep sea formations and set up transport channels, Clean energy from the deep sea can reach thousands of households ." China Sea Oil "Deep Sea No .1" gas field development drilling and completion project director Liu Hexing told reporters. Currently, The Deep Sea No .1 gas field production pipeline has been connected to the clean energy supply network around Hainan Island. After the gas field was put into operation, Will become the main gas field to ensure the construction of energy supply in Hainan Free Trade Port and Guangdong-Hong Kong-Macau Greater Bay Area, Each year will be a stable gas supply of 3 billion cubic meters for Guangdong, Hong Kong, Qiong and other places.
