The "Sea-based No. 1" deep-sea heavy vehicle was put into operation to open up a new model for the development of deep-water oil and gas resources in China

On October 3, the first deepwater duct frame platform in Asia, "Haiji No.
1", independently designed and built by CNOOC, was put into use, marking China's successful opening up of a new model for oil and gas development of deepwater fixed platforms, and the design, construction and installation capabilities of deepwater super-large pipe frame platforms have reached the world-class level, which is of great significance for promoting the increase and production of
offshore oil and gas reserves and ensuring national energy security.

The conduit rack platform is the world's most widely used offshore oil and gas production facility
.
"Haiji No.
1" is located in the waters of the Pearl River Estuary Basin, the total height of the platform is 340.
5 meters, exceeding the Beijing International Trade Center, the total weight of more than 40,000 tons, the height and weight have refreshed the record
of China's offshore single oil production platform.

"Haiji I" has put into production of 5 production wells at the same time, with an initial daily output of about 2,700 tons
.
Relying on "Haiji No.
1", Lufeng 15-1 and Lufeng 22-1 will be developed at the same time, with a total of 14 production wells and 3 water injection wells, and the peak daily crude oil output will reach 5,000 tons
after all of them are put into operation.

According to Deng Changhong, deputy general manager of CNOOC Shenzhen Branch, the pipe rack platform is usually used for the development of oil and gas resources in shallow waters, and the operating water depth of more than 300 duct rack platforms in China before is not more than 200 meters, and floating production platforms and underwater production systems
are usually used in the sea area of 200 meters and above.
"Haiji No.
1" is China's first attempt at deepwater duct rack platform development model, the production system from the underwater to the platform, with low development investment, low production costs, high localization rate of significant advantages, its successful application for the economic and effective development of China's deep-water oil and gas resources opened up a new road
.

CNOOC is the largest offshore oil and gas producer in China
.
It is reported that after 10 years of rapid development, the company has formed a "deep-water fleet" represented by "Offshore Oil 201" and "Offshore Oil 720", successively overcome world-class technical problems such as conventional deepwater, ultra-deepwater and deepwater high temperature and high pressure, formed a series of deepwater technology systems with independent intellectual property rights, and has a comprehensive operation capability from deepwater to ultra-deepwater, from the South China Sea to the polar, making China one of
the few countries in the world that can independently carry out deepwater oil and gas exploration and development.

Wang Dongjin, chairman of CNOOC, said that China's deepwater oil and gas exploration and development is still in its early stages, and the prospects for increasing reserves and production are broad
.
At present, the total proven natural gas reserves in the three basins of Yinggehai, Qiongdongnan and Pearl River Estuary in the South China Sea of China are nearly 800 billion cubic meters; A number of deep-water oilfields have been discovered in the Pearl River Estuary Basin, achieving a major historic breakthrough
in deep-water crude oil exploration in China.
In the future, CNOOC will continue to increase domestic oil and gas exploration and development, with the goal of "finding large and medium-sized oil and gas fields" and being the "main force"
to ensure national energy security.
