Bohai Bohai! Another Important Discovery_ 东方 富 网

Original title: Bohai Bohai! Another Great Discovery

CNOOC announced today (22) that the Bozhong 13-2 oil field located in the Bohai Sea has tested 100 million tons of geological reserves. This is after Bozhong 19-6 got 100 billion cubic meters of gas field, my country got another 100 million tons in the Bohai Sea. Large-scale oil and gas discoveries. The Bozhong 13-2 oil field is located in the central waters of the Bohai Sea, about 140 kilometers from Tianjin, with an average water depth of about 23.2 meters. The Bozhong 13-2-2 discovery well encountered an oil layer with a thickness of approximately 346 meters, and the drilling depth was 5223 meters.proofThe average daily production from this well is about 300 tons of crude oil and about 150,000 cubic meters of natural gas. The oil field is characterized by its lightness and high quality.

　　CNOOC Exploration DepartmentGeneral managerZhou Xinhuai:The discovery of Bozhong 13-2 achieved a breakthrough in the exploration of “covered” deep buried hills in the Bohai Sea, greatly expanding the space for buried hill exploration and has significant promotional value for future hill exploration. similar buried in Bohai. Sea and offshore of my country.

To achieve efficient reserve conversion, CNOOC’s innovative exploration and development application integrationmanagementThe model uses existing oilfield facilities to rapidly promote test production in the well area, and exploratory wells are directly converted to production wells, saving more than 70 million yuan in drilling costs, cutting in greatly the oilfield production cycle and increasing oil and gas. production.

　　Director of the CNOOC Exploration DepartmentmanagerZhou Xinhuai:During the “14th Five-Year Plan” period, we will continue to promote the deployment and implementation of the overall development plan of Bozhong 13-2. The project is estimated to be built in 2023 and peak annual production will reach 1.2 million tonnes of oil equivalent, making a significant contribution to the 40 million tonne increase in oil in the Bohai field.

　　News background: Exploration of the primary oil and gas field on a buried hill in the Bohai Sea made great stridesAs the largest offshore oil field in my country, Bohai Oilfield has produced nearly 500 million tons of oil and gas since its development in the 1960s. In recent years, scientific researchers have continually strengthened innovations in the geological understanding and exploration technology for complex geological structures, such as buried hills, and have made a number of important oil and gas discoveries. Already half a century ago, my country began exploring for oil and gas in geological structures on hills buried deep in the Bohai Sea. After several generations of continuous exploration by explorers, it has successfully discovered large and medium oil fields such as Jinzhou 25-1 South and Bohai Sea. A large-scale integrated gas condensate field of 19-6 billion cubic meters

　　Zhou Xinhuai, General Manager of CNOOC’s exploration department:The main area discovered by Bozhong 13-2 belongs to the archaic buried hill, which is covered by a very dense and thick Mesozoic stratum, like a thick cotton hat on the top of the head, so the deposit, accumulation and transport The two main problems of migration mode are very difficult to solve, and the depth of exploration is deep, so the explorationcostVery high, CNOOC has not made large-scale exploration breakthroughs in this field.

If there are high-quality reservoirs and if oil and gas reservoirs can form around the buried Archean hills.objectives, CNOOC explorers through geological knowledge innovation, proposed a new understanding of the accumulation model, discovered the Bozhong 13-2 oil field, enriched their knowledge and experience in the field of buried hills exploration, and reached the goal of 30 million tons of oil per year. for the Bohai oil field Consolidated the reserve base.
