Zigong Well Salt System Of Deep Drilling Techniques

    Sichuan well salt has a long history, according to literature and expert research, world-renowned British County Zhuo Tsutsui was founded in the Northern Song Dynasty Qing calendar year, 800 years earlier than in the West should be. «China’s drilling technology History», «History of Science and Technology», «well salt Science and Civilization in China» and other works of them registering it as «the father of the world’s oil drilling», «create a precedent of mechanical drilling.» Compared with the British counties, Zigong’s well salt mining is a large, well known.

    Salt Well in history had the most prosperous period of Zhuo Tsutsui 1711, an annual output of more than 4000 tons of salt, and now the British county still preserved the ancient salt well 41 that the distribution within a radius of 6 km. It followed the Song Dynasty learn the system well salt of the process, including drilling, take brine, drying brine (filtered halogen), fried salt processes. Well salt skills has led to the invention of rope-style Cotton drill drilling technologies emerge, so that the natural brine deep underground has been mining.

    Known as the Chinese Yandu Impact of Zigong City is the birthplace of Dayton filed drilling technology, this technology has experienced large shallow wells, the Eastern Han Dynasty to Song Dynasty, the gestation period of the Song Dynasty Zhuo Tsutsui transition, the Ming Dynasty to the Qing dynasty of small deep wells of the and maturity stage of development, there are 1900 years of history. AD 1835, the world’s first ultra-km deep mouth — Sea wells (1001.42 meters) of hewn, is China’s drilling technology, Dayton important sign of maturity, its development of the world’s drilling technology has played a catalytic role. Leighton drilling technology, including drilling, logging, and corrective ramp to fill cavity, salvage, Shuji wooden pillars and other processes, it is well salt production in Zigong as early as the extensive use of so that in the Qing dynasty gained the «rich A full-chuan,» the reputation of the Republic of 28 years of Zigong, «because of salt, a city,» but today has grown into a population of 3.2 million has a historical and cultural city.

    Zigong City, and the British counties well salt sink transmission system of art almost millennium, the process is still preserved as the world’s deep drilling of the living fossil, should take practical measures to be of special protection.
