The application software under the traditional java framework lacks the ability of modularization and dynamic management. Based on the in-depth study of OSGI framework, this paper proposes a method of combining the OSGI and the hierarchical decoupling. It uses the method to design the overall architecture of downhole operation management system, and also solves the problem of dynamic management and service layer. It describes the application of OSGI extension point mechanism and AOP in detail, then improves the system expansion ability and solves the problem of data synchronization update. The test results show that the model can improve the performance of the system, reduces the coupling between the modules, increases the reusability of components and scalability, and improves the stability of the system.
