Research On Information Model For Fracture And Workover For Donwhole Job

The current production companies generally lacks of scientific data management. Inorder to improve production efficiency and downhole job quality and to strengthen theenterprise competitive power, we should use standard technology and enterprise informationresource planning theory as the guide. We can solve the problem of data from scattered,professional management mode to the standardization, integration and professionalmanagement mode. We can make software applications separate from the data preparationand maintain and devote themselves to professional applications. In order to realize the longterm goal of “digital downhole”, we should make downhole job branch production andresearch the core. We should construct united, high quality and safe data sharing environmentto meet the demand of downhole job branch companies’ production and scientific technology.Thus we can also support the various business data. These data show the businessrequirements of branch companies from the construction design, construction, productioncommand and construction process management, construction effect analysis and research.We can provide comprehensive and integrated data for downhole production, managementand upper decision.This theme mainly studies two main businesses, establishing the functions of thebusiness process model domain, business model, data elements dictionary and data model.These information models are primary content of underground data center. The research andestablishment of the information models involves all aspects of information technology.And then, under the guidance of these standards, we construst the functional domain model,business process model, event model of the downhole fracturing and operations. At the sametime, we analyze all kinds of datas involved in every business process of every function.Wealso define the data element dictionary of the two main businesses according to theconstruction standards of data elements. According to this, the business data dictionaries aremixed together, extracting public model and business data model.Because data models of the data center use POSC’s many advanced ideas, the modeldesign is scientific, advanced; because the model designs are designed closely around thedownhole jobs, they extend POSC’s modeling thought. So downhole data center models notonly adopt advanced iedeas of POSC’s model consturction, but also promote it in the fact andform central theme business model of downhole data center. Be due to analy POSC instandards, thus downhole job data center model standards fit EPDM totally.
