Exploring the depths: China's 30,000-foot borehole experiment

A puzzling experiment

As reported by Xinhua, an English-language Chinese newspaper, China achieved a significant milestone in deep-Earth exploration on March 4, 2024. The country successfully drilled a borehole that reached a depth of 10,000 meters (32,808 feet).

The goal: drill 11,100 meters

The drill being used is called the Shenditake 1, and according to Xinhua, it is expected to drill even deeper. The goal is to reach 11,100 meters below the Earth's surface. This is the first borehole experiment in China ever designed to go deeper than 10,000 meters.

China's deepest well

The drilling is taking place in the Tarim Basin in the oil-rich Xinjiang Uygur Autonomous Region. The question many have is why does China want to drill this ridiculously deep borehole?

The core of the earth

China has been one of the countries most interested in exploring the Earth's crust for decades, and it seems that they are now ready to get as close to the Earth's crust as possible to step up this research.

One step further

In fact, the Asian giant has been exploring the Earth's interior for years, but with this hole, they aim to go where no one has gone before.

Minerals, energy resources

The aim is, a priori, to discover minerals or energy resources that can be used to improve the country's economy, China Daily reports.

Prevention of natural disasters

Incidentally, as Chinese President Xi Jinping confirmed in 2021, this mega-project will serve to assess and - perhaps - prevent future natural disasters such as volcanic eruptions or earthquakes.

10 continental layers

To this end, the plan was made to drill the deepest borehole in China's history. According to Bloomberg, it will be a narrow hole that will cross 10 continental layers.

In search of the distant past

The goal is to reach the Cretaceous system in the earth's crust, where they expect to find rocks more than 145 million years old, according to state-run Xinhua news agency.

Large tonnage machines

To carry out this project, China will use a 2,000-ton oil rig with high-tech drill bits and drill pipe, Interesting Engineering reports.

Problems with the environment

The area chosen for this nearly infinite well has an additional problem, which is a very dry climate. It lies in the Tarim River basin and adjacent to the Taklamakan Desert, the largest desert in China, Xinhua reports.

Sea, mountains and desert area

This is an area with a very difficult terrestrial environment coupled with unfavorable subsurface conditions makes the drilling even more complicated.

Prepare for the operation

Currently, the team in charge of this complicated project is prepared for months to complete this challenging task.

Everything fixed before they start

The risk, danger and complexity involved in such a mission justify taking every possible precaution.

An unprecedented project

"The difficulty of the project is comparable to driving a large truck on two thin steel cables," Sun Jinsheng, a researcher at the Chinese Academy of Engineering, told the Economic Times.

Not the deepest on earth

Despite the 10,000 meter deep Chinese hole, the world's deepest borehole is still Kola Superdeep, the Russian well drilled by the Soviet Union between 1970 and 1992.

12,262 meters

Also called SG-3, it is located on the Kola Peninsula in the Pechengsky area. It reached a depth of 12,262 meters.
