en.Wedoany.com Reported - On June 16, with the successful loading of the final platform onto a vessel in the Binhai New Area of Tianjin, the land-based construction of all platforms for the Bozhong 26-6 Oilfield Development Project (Phase II), the world's largest metamorphic rock oilfield, has been completed, laying the foundation for the oilfield's scheduled production.
Located in the central Bohai Sea, the Bozhong 26-6 Oilfield has its reservoir in the Archean buried hill metamorphic rock formation at a depth exceeding 4,500 meters. It is the world's largest metamorphic rock oilfield, with cumulative proven oil and gas geological reserves exceeding 200 million cubic meters. The Phase I development project was officially put into production in February last year. The Phase II project will install two new wellhead platforms offshore, consisting of jackets and topsides. The two wellhead platforms, whose construction has now been completed, will operate unmanned.
During the construction of the platform topsides, the project leveraged the intelligent manufacturing model of CNOOC Engineering's Tianjin Intelligent Manufacturing Base and actively promoted integrated construction. The project introduced welding robots, and through tooling modifications and program optimization, welding efficiency was improved by 20%.
As a key carbon dioxide capture and utilization demonstration project planned by CNOOC in the Bohai Oilfield, and a critical support for studying the geotechnical properties and bearing capacity laws of the Bohai region, the Bozhong 26-6 Oilfield carries multiple missions, including energy supply security, green transformation, and scientific research. It is of great significance for ensuring energy security in the Beijing-Tianjin-Hebei region and the Bohai Rim area.
Currently, the two platforms have set sail for the central Bohai Sea to commence offshore installation operations.
