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.

Chinese stocks closed higher on Friday, due to stimulation from the newly-released US technology earnings, said China Global Television Network (CGTN) analyst Timothy Pope.

The benchmark Shanghai Composite Index up 0.72 percent to 3,832.26 points.

The Shenzhen Component Index closed 2.21 percent higher at 13,578.93 points.

The ChiNext Index, tracking China's Nasdaq-style board of growth enterprises, gained 3.06 percent to close at 3,343.96 points.

"The latest U.S. technology earnings have made Chinese AI stocks whipsaw over the past couple of sessions. Before we get into that, as far as the dust is settling, the Shanghai Composite added 0.7 percent today, the Shenzhen Component rose 2.2 percent and the ChiNext gained 3 percent. And those numbers just screamed technology rebound," Pope said.

"Yesterday's sell-off was absolutely brutal after we saw the results from Meta and other U.S. technology companies reviving concerns about the hyperscalers' enormous AI spending. The worry is that they may be investing too much, too quickly, without generating returns fast enough to justify that. That punished both ends of the market: it hit the U.S. technology giants because of the scale of their spending, and it hit their suppliers in China because it cast doubt on future demand. But then we got results from Azure -- Microsoft's cloud-computing division -- and the market grabbed at those like a lifebelt. Azure's revenue grew faster than expected, demand is still exceeding Microsoft's available computing capacity, and the company says its spending will continue. That is fantastic news for Chinese optical-transceiver companies, data equipment makers, semiconductor firms and memory-chip producers-basically the entire AI supply chain. And it is those shares currently underpinning gains on the Chinese mainland market," he said.
