Research On Construction Technology Of Oilfield Data Resource Catalogue

With the advent of DT era,data have become the most important resource today and in the future.The extensive construction of enterprise big data platform has made the digital transformation of enterprises an inevitable trend,and enterprise data governance has gradually been valued.In the process of informatization construction and data resource governance and management of enterprises,there are some problems such as data "invisible",difficult to recognize,integrate and apply,inconsistent data standards,and inadequate data sharing caused by information islands.Therefore,this paper mainly studied the construction technology of data resource catalog to realize the unified organization management and open sharing of enterprise data resources.This paper mainly studies the construction technology of enterprise data resource catalog,proposes "business-data-system association method" as the methodology of data resource catalog construction,and divides the phases to explain the construction steps.The construction process is abstracted into the stages of business combing and business modeling,data resource collection and classification inventory,governance,planning,data resource catalog construction and resource linkage.This paper focuses on three aspects: the research on the establishment of enterprise business model construction method,the research on the design method of global data model and the research on the construction method of data resource catalog.1.Research on business model construction method.Around the triangle relationship of "business-object-activity",this paper analyzes the data generation / use relationship in the business process,sort out the business architecture according to the hierarchical structure of "business domain-business classification-business activity",and establishes data integration-oriented business models,according to the business activities / objects in the business process / theme,covering all businesses and the whole life cycle of business activities.2.Research on the design method of global data model.Starting from the business,this paper thoroughly combs the current situation and requirements of enterprise business,data resources and systems,build a data integration-oriented enterprise business model,and sort out enterprise data resources based on the enterprise standard data model combined with business system data models,user views and business needs,etc.,launch enterprise data resource planning,design a unified data element standard system as the data resource description standard based on national standards,industry standards and the application and demand of enterprise business practice,and design the standardized enterprise data architecture based on the business object model to etablish a global enterprise data model.3.Research on the construction technology of data resource catalog.Based on the research and analysis of enterprise business architecture,data and application architecture,"business-data-system association method" is proposed as the methodology of data resource catalog construction.The data resource catalog is constructed in a business-driven manner,and the status and requirements of enterprise business,data resources and systems are sorted out,and a data integration-oriented business model is established according to the "business-activity-object" idea.The enterprise data resources are comprehensively combed and checked from the three aspects of achievement,application and demand,launch enterprise data resource planning,design a standardized global data model to realize the classification and organization of data resources,and construct a multi-dimensional enterprise data resource catalog based on business classification,application classification,system classification,etc.,to form a "general ledger" of enterprise data resources,to achieve unified management and orderly organization of the achievements,applications and requirements of enterprise data resources,and face the entire enterprise all kinds of data users provide directory services for sharing,opening,searching,locating and acquiring data resources,promote the transition and transformation of controlled data governance to service-oriented data governance,and provide ideas and methods support for the architecture design and function development of resource catalog management system.Finally,the methodology was applied in Jidong Oilfield Company to construct oilfield data resource catalog,effectively solve the problems of oilfield data governance,and demonstrate the feasibility of the methodology.
