Abstract: Internet technology is very much coming into its heyday and is now entering the era of “Internet plus”. Especially, cloud services and cloud applications are supporting rapid informatization in every industry. The petroleum industry, and other traditional energy industries, have also been carrying out information system construction. However, there are major challenges facing the petroleum industry in how to achieve migration to cloud-based computing—essential for the future to take advantage of the cloud’s ability to support rapid development of business software and applications. Petroleum research has its own specific requirements and a need to rapidly acquire business software and other technology for information system construction such as big data, artificial intelligence, etc. The Dream Cloud App Store solves this problem and fills the requirement for an application sharing platform. The App Store gathers together professional petroleum software, artificial intelligence, and big data technology. Based on E&P Dream Cloud and relying on the Data Lake and PaaS platform within the Dream Cloud environment, the App Store provides an end-to-end utilization interaction (UI) platform for the petroleum industry, effectively supporting application sharing and construction in the oil and gas industry, accelerating rapid informatization and promoting an opening, collaborative, sharing and intelligent eco-environment within the upstream business.
