In recent years, the oil and gas production of the Bohai oil field continues to grow, and the research tasks increase ceaselessly, researchers spend more time on using various kinds of petroleum softwares. Because there are many softwares and they have a large number of modules, so we must strengthen the software management, and ensure the purchase and distribution of software module rational, so that we can meet the needs of scientific research works. Thus we developed the professional software usage information intelligent analysis system. This system can automatically gather and count module usage information, and provide convenient and efficient search function with B/S mode. The system also provides the necessary decision information for enterprise manager and system administrator. And we have successfully extended the system to each branch of CNOOC Limited and have achieved good results. This paper introduces system structure and how to design and realize the system.
