Research And Application Of Oilfield Well Completion Information Integration Framework Based On Metadata

Oilfield well completion is an important part of oil production capacity building.Numerous sources of well completion management information,the difference of the same information handling and analysis angle between the various fields,as well as the lack of acquisition and description,causing information integration and resource sharing have become increasingly difficult.But,the effective planning and integration of the various information involved in the well completion management are beneficial to the sharing and integration of well completion information,which can promote the information exchange and cooperation in the fields of well completion and improve the information management level of the oilfield well completion.Therefore,it is of great practical significance and high research value to research the information integration of oilfield well completion.In this paper,the integration framework of "user-entity object-function" was used as the integration core,based on the theory of metadata and meta-model driven,as well as the theory of middleware integration and GIS related technologies,combined with the information management status of oilfield fields and the actual needs,to organize,plan and integrate the information of well completion,and ultimately to achieve the information integration of well completion in the GIS.The main research contents of this paper are summarized as follows:1.Oilfield well completion information integration requirements analysis and overall designThrough the detailed analysis and summarization of the business in the fields of the actual production of the oilfield well completion,the key points of the information integration are analyzed,and the integration framework based on the user-entity object-function is applied to organize the information of well completion,and analyzed the elements and the relationship between the elements in the framework.Then,the overall design is proposed,with meta-model driven technology and middleware technology as integration methods,the four-layer architecture are put forward.2.Detailed design of well completion information integration modelBased on the analysis of the requirements of well completion information integration and the overall design,through the analysis of the data model of well completion and GIS spatial,based on the metadata modeling technology,the integration framework of "user-entity object-function" as the integration guide,designed and implemented the meta-model of oil field well completion information integration system,and through the middleware technology,achieved the data integration of the model.3.Based on the completion information integration framework researched in this paper,the application system function is designed and realized,and the application effect of the system is nice,and the research work and disadvantages are summarized.
