China Ocean Petroleum Co., Ltd. announced on Wednesday (19th) that the first deep-water deep atmosphere of deep-water deep atmosphere is found in the Qiongdong South Basin of the southeast of Hainan Island on Wednesday (19th).50 billion cubic meters.
According to interface news reports, CNOOC introduced that the Treasure Island 21-1 has a large-scale Delta development structural background, most likely to be a large and medium-sized gas field.The deployed first -mouth pre -detecting well diamond gas layer was 113 meters, setting the thickest record of the single -well air layer in the deep water area.
After testing, the pre -detecting Nissan natural gas was 587,000 cubic meters.Repeated natural gas proved geological reserves exceeded 50 billion cubic meters, and condensed oil proved that the geological reserves exceeded 3 million cubic meters.
In the field of marine oil and gas exploration, waters with water depth exceeding 300 meters are generally referred to as deep water, and wells with a well depth of more than 3,500 meters are defined as deep wells.The Treasure Island 21-1 gas field discovered this time is located in the deep water area of the southeast of Hainan Island. The maximum operating water depth is more than 1500 meters and the drilling depth is more than 5,000 meters.Extremely complex.
According to the overall planning of China Sea Oil, by 2025, the overall proven natural gas reserves of the three basins of Yinggehai, Qiong, and Pearl River in the South China Sea can reach 1 trillion cubic meters, and it will be established "trillion squaresAtmospheric area.Through the largest "Yicheng-Hong Kong" underwater gas transmission in Asia, these natural gas will be directly connected to the Guangdong-Hong Kong-Macao Greater Bay Area and Hainan Island.
