China's first independently developed intelligent drilling system put into operation

China's first independently developed intelligent drilling system, the "Changlong", has been officially put into operation, marking a significant milestone in advancing the digital and intelligent transformation in the country's energy sector, according to China National Petroleum Corporation (CNPC) on Wednesday.

The "Changlong" intelligent drilling system integrates intelligent drilling rigs, intelligent well sites, and intelligent decision-making platform into one unified system, capable of providing intelligent engineering support for oil and gas exploration at depths of nearly 10,000 meters underground.

The intelligent system enables real-time data exchange between downhole sensor networks and intelligent platform on the ground, automatically executing critical operations including collecting geological parameter, optimizing drilling trajectory, and monitoring equipment status, significantly enhancing both drilling efficiency and operational safety.

"The 'Changlong' intelligent drilling system has achieved drilling operations for the first time in the country, realizing full-process automation control in 'measurement-analysis-decision-execution,' which has replaced manual operations and decision-making with intelligent technology," said Chi Lijun, deputy manager of PetroChina Great Wall Drilling Company.

The system has not only achieved full-process digitalization of drilling operations, but also established internationally advanced oil and gas exploration and development solutions. "The 'Changlong' intelligent drilling system has achieved multiple technological breakthroughs, offering oil and gas exploration and development solutions at an internationally advanced level. It has laid a solid foundation for further exploration of intelligent drilling in the future and provided strong support for the efficient development of inner-earth resources and better safeguarding national energy security," said Yin Jiafeng, general manager assistant of PetroChina Great Wall Drilling Company.

China urges Mexico to step back from imposing protectionist tariffs at an early date, Foreign Ministry spokesman Guo Jiakun said at a press briefing in Beijing on Thursday.

Guo made the statement in response to a media query regarding the Mexican Senate's approval of a new tariff bill that would levy tariffs of 5 to 50 percent on some imports from China and several other Asian countries starting from next year.

"Competent authorities of China has made a response on this, which you may refer to. Let me stress that going against the trend of economic globalization and resorting to protectionism serves no one's interests. We hope Mexico will correct the wrongdoing at an early date and work with China to uphold the overall economic and trade relations between the two countries," said Guo.
