Скачать или смотреть China’s ice-resistant drilling tech pushes Bohai oilfield’s annual output to record 30 million tons

This is China’s northernmost offshore oil field, “Jianzhou”

In winter, the depth of the ice can reach 20 to 40 centimeters

When the hard sea ice is moving, its impact force on the oil production platform is equivalent to 5 to 6-magnitude earthquake

New ideas popped up when struggling with the extremes with China building the world's only ice-resistant platform

Technicians also used new encryption for the offshore cluster-well pads

The new tech supports operating 88 wells simultaneously at one platform

“Bohai”, the owner of “Jianzhou”, has become China’s largest crude oil producer with the output hitting over 30 million tonnes (or 602,640 barrels per day) in 2021

That accounts for one seventh of China's yearly yields, which can refuel 290 million vehicles nationwide for 1.5 times

To reach the record high, 488 wells were operated simultaneously in 2021
with a total drilling footage of 1.12 million meters, as high as 126.6 Qomolangmas
