This drilling of China’s deepest well began on May 30 in the oil-rich region.
It will penetrate 145 million year old rocks.
“It was not an easy project. The construction of something like that could be compared to a large truck riding on two thin steel cables,” said Sun Jinsheng of the Chinese Academy of Engineering.
The deepest hole dug by man in the Earth is still the Russian super-deep borehole Kola, which in 1989, after 20 years of drilling, reached a depth of 12,262 meters.
