Where is the world's first artificially drilled ultra-thousand-meter-deep salt well located?

The Stanley Well in Zigong, Sichuan Province, is the world's first artificially drilled, over 1,000-meter-deep salt well.

According to the U.S. authoritative data, later than the Stanley Wells 10 years in the United States in the Canova region of a record-breaking brine wells, wells but only 1,700 feet (518.17 meters), while the Stanley Wells wells to reach a depth of 1,001.42 meters, has long been far ahead of the world's deep wells drilling record before the middle of the 19th century, showing that China's ancient wells and salt drilling technology has been developed to the stage of maturity, the world's first manually-drilled salt wells. It is a milestone in the world drilling history.

"Stanley" is a metaphor for a blazing well fire, and "sea" is a metaphor for abundant brine. Sun Sea wells were drilled in 1832, using the traditional Chinese percussion (ton drilling) drilling method, relying on pestles and artificial, took three years, in 1835 drilling to 1001.42 meters deep brine, is the world's first over 1,000 meters of deep wells, marking China's leading level of drilling science and technology.
