On the morning of March 26, Liu Liehong, Secretary of the Party Leadership Group and Director of the National Bureau of Data, visited PetroChina to investigate the construction of the Kunlun Big Model and high-quality data sets in the oil industry, and held discussions with leaders of PetroChina, China Mobile, Huawei, iFLYTEK and other units. Liu Liehong pointed out that the research and development and application results of PetroChina's Kunlun Big Model in the oil and gas industry chain are worthy of recognition, and PetroChina's typical practices such as building an innovation consortium and insisting on scenario-driven development are worth learning from. It is hoped that PetroChina will seize the opportunities of artificial intelligence development, accelerate the application of industry big models, further improve the level of data resource development and utilization in the oil industry, and play a greater role in promoting the market-oriented allocation reform of data elements and accelerating the construction of Digital China.
