Abstract: The development method of functional customization based on Petri net and component technology is proposed, aiming at the problem of low modularization and flexibility of the system in the digital archives of oil field. The object-oriented colored petri net is adopted to realize the hierarchical modeling and the reset arc is added to optimize the workflow of the archives' invocation. The rationality of the model is analyzed through the correlation matrix and the reachable graph and the other related theory. The component information base is built by the model's extraction. The components are called in order and the custom function of business is completed by using information base and business logic of customers. In the application, the system is flexible, adaptable, the file transfer speed is fast, and the needs has been met in the actual application.

Key words: reset arc, object鄄oriented colored Petri net (OOCPN), components, Petri net, function customization
