Human beings have entered the era of artificial intelligence. In recent years，artificial intelligence has been widely used in strategic decision-making，safe and efficient intelligent production，reservoir prediction，fault diagnosis and risk early warning of oil and gas exploration and production，intelligent site and equipment management，intelligent scheduling and prediction，early warning and supervision control of oil and gas storage and transportation，process management and supply chain optimization，equipment monitoring and remote diagnosis of oil and gas refining. However，it is still in its infancy. The application of artificial intelligence in oil and gas industry will be conducive to improving operation efficiency，promoting energy conservation and emission reduction，promoting the pace of intelligent factory construction，promoting energy revolution and ensuring national energy security. As a general purpose technology，artificial intelligence still has great application potential in oil and gas exploration and production，storage and transportation，refining and other aspects in the future.
