The first self -developed shallow water underwater underwater oil collection tree in my country is put into use

Today (17th), China Sea Oil released news. With the successful ignition of the 31-1 gas field of Jinzhou in the Bohai Sea, the natural gas dragon buried in the underground for more than 2,000 meters through the underwater oil tree system was stably transported to the platform torch arm, marking our country The first self -developed shallow water underwater oil collection system was successfully put into use.

Underwater oil collection trees are one of the core equipment indispensable underwater production systems. It connects oil and gas and external oil and gas transportation pipelines from depths of the strata. Underwater oil collection trees can control the speed of oil and gas mining, real -time monitoring and adjustment of production conditions, just like the intelligent "faucet" of oil and gas field wells. For a long time, only a few companies in the world have mastered the design and manufacturing of underwater oil collection trees. The total growth width of the underwater oil collection trees in the water underwater is 3.3 meters, only 2.65 meters in height, and the overall weight is 24.8 tons. Compared with the height of conventional underwater oil collection trees, the height of the underwater mining is nearly 25%, the weight is reduced by 35%, and it has a compact type. , Lightweight characteristics.

Mi Lijun, general manager of CNOOC Research Institute: The system's autonomous technical research lasted for three years, and completed the design, processing, assembly and testing of 1358 components, and the localization rate reached 88%. The successful independent research and development of my country's first domestic shallow water underwater oil collection system has achieved the historic breakthrough of the shallow water underwater mode from "0" to "1" in my country's shallow waters.

The Bohai Oilfield is the largest crude oil production base in my country. The area of ​​the Bohai Sea where the oil field is located is about 77,000 square kilometers. The fishery, shipping and oil and gas development industries are developed, and the multi -functional overlap in the sea area. In order to solve the problem of the use of sea and ensure the increase in oil and gas storage and production. Since 2019, China Oil has started to carry out technical research on shallow water production systems. It is planned to replace the pipe rack platform on the sea surface through the underwater production system, so as to achieve it on the sea, so as to achieve it Effectively develop oil and gas resources without affecting the needs of shipping. my country's independent research and development of underwater oil collection trees specifically designed the "full package" external protective device, which can effectively avoid safety risks such as fishing nets dragging and ship breaking down. It is more suitable for shallow water. The entire system can run normally on the bottom of the sea for 15 years.

Yu Guimin, chief engineer of CNOOC Tianjin Branch: At present, the reserves of more than ten blocks in the Bohai Sea are limited. It is found that oil and gas resources are found but cannot be developed. Used, this will contribute to 40 million tons of oil in the Bohai Oilfield in 2025.
