My Country's First Oil And Gas Production System Under The Seabed Mud Surface Completed Testing

The underwater production system is an indispensable core equipment for the development of offshore oil and gas fields. Recently, all tests of the underwater production system of the Jinzhou 25-1 West Oilfield Well Area 1 development project have been completed. This independently developed and manufactured underwater production system can be installed under the seabed mud surface, bringing technology to the development of my country's offshore oil and gas fields. breakthrough.

The underwater production system of the Jinzhou 25-1 West Project has complex processes, and many technologies are being attempted for the first time. All equipment is concentrated in a steel cylinder with a diameter of 24 meters below the mud surface. The installation space is very narrow, which places extremely high requirements on integration testing. .

Zhang Meng, deputy general manager of the Engineering Project Branch of Offshore Oil Engineering Co., Ltd.: By giving full play to the advantages of the entire industry chain of offshore oil engineering, we will concentrate our efforts on technical research and fill 12 technical gaps in the industry. It took more than 2 months to complete 23 complex tests including underwater control system integration, underwater structure, and installation simulation to ensure the safety and reliability of the system structure, communication, control, and stability, laying a solid foundation for subsequent offshore installation and system joint debugging. Base.

It is understood that deep-sea underwater production systems are usually installed on the seabed. Due to the shallow water depth in the Bohai Sea, frequent fishing and navigation activities pose serious challenges to the safety of underwater production systems. CNOOC pioneered the steel underwater production protection system, which was installed under the seabed mud surface to cover the production tree, manifold system, connection system, underwater control system, etc., to comprehensively protect the underwater production system from damage. .

Meng Fanran, person in charge of the Jinzhou 25-1 West Oilfield 1 Well Area Development Project of CNOOC Tianjin Branch: Through independent innovation of the steel cylinder protection system under the seabed mud surface, it will provide important technical support for the future development model and production and operation methods of the Bohai Sea oil and gas fields. , effectively unleashing the development potential of oil and gas resources in the restricted waters of the Bohai Sea, and further enhancing my country's independent energy supply capability.

It is understood that in the next step, the underwater production system of Jinzhou 25-1 West Project will be shipped to sea for installation in the near future, and every effort will be made to ensure that the project is put into production on schedule this year.
