Abstract: With rapid development of big data technology, the storage and processing capacity for huge amounts of data has been continually improved, leading information technological development. This technological development not only triggers reform of information technology and E-commerce but also exerts a far-reaching influence on the traditional energy industry like the oil and gas sector.This paper elaborates the application methods and cases of big data technology in business management, exploration and development, engineering technological service, oil production, oil refining, and marketing of the oil and gas industry. From a number of angles, it displays the oil and gas industrial reform led by big data technology. Meanwhile, the paper also focuses on the issues and challenges arising from the reform, such as no clear big data demand from business departments, seriously isolated internal data of the enterprise, and lack of big data talents.
