CNPC completes oil well drilling work in Tarim

China National Petroleum Corp (PetroChina), the country's biggest oil and gas company, said on Monday that it has achieved a significant technological breakthrough, after successfully completing drilling work on the deepest oil well on land in Asia at its Tarim oilfield in the Xinjiang Uygur autonomous region.

The Luntan One well, with a current depth of 8,882 meters, broke the previous record of 8,588 meters set by Sinopec in February 2019, according to PetroChina Tarim Oilfield Co.

The company, which started to drill in June 2018, has overcome the difficulties posed by ultrahigh-temperature and ultra-high-pressure conditions, said Cai Zhenzhong, head of the company's resource exploration department.
