According to CCTV News Client, China National Offshore Oil Corporation html released a news on the evening of the 219th that it had another major breakthrough in the Qiongdong Basin in the southeastern sea of Hainan Island . It discovered that my country's first deep-water deep-sea gas field - Baodao 21-1. Its geological reserves exceeded 50 billion cubic meters, achieving the largest breakthrough in Songnan-Baodao sag in more than half a century, and it is a powerful progress made in accelerating deep-sea exploration.
In the field of marine oil and gas exploration, waters with water depths exceeding 300 meters are generally called deep water, and wells with well depths exceeding 3000 meters are defined as deep wells. The Baodao 21-1 gas field discovered this time is located in the deep water area of the southeastern sea area of Hainan Island. The maximum operating water depth exceeds 1,500 meters, the drilling depth exceeds 5,000 meters, and about 150 kilometers away from the "Deep Sea One" ultra-deep water gas field. The marine geological conditions are extremely complex.
Wu Keqiang, chief geologist at Hainan Branch of China National Offshore Oil Corporation, said that the successful discovery of Baodao 21-1 not only confirms the exploration potential of Baodao sag, but also shows that we have made important breakthroughs in deep water and deep exploration technology and are of great guiding significance for the exploration of similar strata systems.
