On April 8, Beihai, Guangxi held the commissioning ceremony of Weizhou 12-8 oilfield.
It is reported that the "Haiyang Shiyou 163" platform used in the oil field is China's first offshore mobile jack-up wellhead platform.
The east area of Weizhou 12-8 oilfield is about 31 kilometers away from Weizhou Island. It is a typical marginal oilfield with high development cost and low input-output ratio.
It is understood that the "Offshore Oil 163" platform has the characteristics of being liftable, movable and reusable. It is called "Little Bee" in the industry. After completing the current development and production tasks, the platform can be lowered to the sea through the lifting system, and the tugboat Towing to a new operating location for continued use, in order to improve the utilization rate of equipment and reduce the cost of oilfield development, is a powerful tool for developing marginal oilfields.
It is reported that the peak daily production of crude oil in the east area of Weizhou 12-8 oilfield is about 1,300 tons, and the cumulative crude oil production can be increased by more than 800,000 tons.
The successful development of this oilfield has broken through the barriers to the development of marginal marine oilfields, which means that China's "bee-style" oil production model technology system is maturing, which has laid a solid foundation for improving China's development capabilities of marginal marine oilfields and "unlocking" hundreds of millions of tons of hard-to-recover reserves. Solid foundation.
