Kola Superdeep Borehole

China drills 6,000 meters into Earth’s crust

Their goal is to reach a depth of arou


In a pioneering venture, Chinese engineers have reached an impressive depth of 6,000 meters by drilling into the Earth’s crust, a project commenced in May. Located amidst the expansive dunes of the Taklimakan Desert, China’s most vast desert, this deep well aims to reach an astonishing final depth of 11,100 meters.

Such undertakings are not just feats of engineering but are laden with significant challenges. As per Xinhua, the colossal equipment for this project, which includes drill bits and pipes, weighs in excess of 2,000 tons. As it delves deeper into the Earth, it transcends through more than ten distinct continental layers.


However, the Tarim Basin, where this venture is stationed, is notorious for its extreme terrestrial and subsurface conditions, making exploration endeavors particularly strenuous.


From a historical perspective

From a historical perspective, the most profound man-made depth ever achieved is by the Kola super-deep borehole near Murmansk, Russian Arctic. Initiated by the Soviet Union in 1970, this borehole reached an astounding depth of 12,262 meters, holding its title until 2008.

The Kola Superdeep Borehole, from 1989 to 2008, was recognized as both the world’s longest and deepest borehole. While its record length was overtaken in May 2008 by the BD-04A extended reach drilling well in Qatar’s Al Shaheen Oil Field, boasting a length of 12,289 meters, the Kola borehole still maintains the record for the greatest depth below the Earth’s surface at 12,262 meters, making it the deepest man-made point on our planet.

As China continues its ambitious drilling operation, it’s evident that the realm of geotechnical engineering is boundless, with nations pushing limits to understand our Earth’s intricate layers better.
