After years development, oil extraction engineering industry’s data increased gradually. And it lacks a unified, interactive, visual information query and display platform. In this paper, firstly the system architecture of oil extraction engineering tools and project simulation system is built. It analyses the basic functions required by the system -the model display, formation of simulation, and production data query. And it describes the key technology to achieve system transformation, including equipment model, formation of the simulation, the realization of human-computer interaction, etc. The system can provide users with complete information from a database query, show each part of component information wellbore, completion status and production measures intuitively. For engineering designers, it helps them to design, report, and analysis.
