Research On Global Share Data Model Oriented E&Papplication Based On UDEF

With the development of the oil fields informationization process, the demands of information sharing in E&P domain have been increasing, while information islands become the barriers which obstacle data sharing among different domains. For breaking the barriers among different business domains, it should establish the E&P global sharing high level data model-conceptual model, starting from the whole E&P. Even though POSC, EPDM, Finder and so on are the data models in E&P, each of them has some defects in a way. Otherwise,there are a lot of conceptual modeling methods, it is difficult to integrate them, so there is not a standardizational and accepted extensively global sharing conceptual model in E&P domain.In order to solve the problems above, this thesis researches the definition of conceptual model, focusing on the key point of conceptual model standardization. It summarises the principles of standardizational conceptual modeling and presents two kinds of standardizational conceptual modeling methods, global sharing high level conceptual model and the process of global sharing conceptual modeling according the ISO/IEC 11179 serial standard,UDEF and IRP methods and so on. These main researches are as follows.First of All, it identifies the core elements of conceptual model-concept and relationshi by making the researching on the definition of conceptual model. According to the core elements of conceptual model, it summarises the key to conceptual model standardization,classifies the relationships among concepts and shows the instance of these relationships in E&P.Secondly, for establishing the principles and methods of standardizational conceptual modeling, it makes researches on 11179 serial standards, analyzing the 11179 related metamodel, summarising conceptual modeling principles. It presents the top global classification model of concept in conceptual model, registration conceptual modeling method based on IRP and reuse conceptual modeling method based on MDR, through the researching of UDEF, IRP methods and so on. Finally, it presents the global sharing high level conceptual model and shows the process of global sharing conceptual modeling process based on the theories above.And then, As to the problem of lacking of global sharing conceptual model in E&P, this thesis presents global sharing high level conceptual model in E&P, combining the theories above with the bussiness in E&P. It shows function areas related conceptual modeling instances based on the well log and single well production bussiness backgrounds. Finally, it summarises the whole process of global sharing conceptual modeling of E&P.Finally, this thesis designs and realizes the EPGSCM registration and management platform based on the research above. It manages the conceptual modeling results.by registry.
