摘　　要：随着油气企业数字化转型的推进,勘探开发领域因数据变更而导致的数据采集、汇聚、管理、处理与应用等相关变更问题日益突出。基于中国海油勘探开发数据湖平台,设计了面向勘探开发数据的元元模型-元模型-元数据的变更影响分析及处理逻辑与方法;基于元数据管理方案,打通了勘探开发数据湖平台数据标准管理、数据模型管理等核心数据存储结构,通过变更影响分析工具,实现对元模型、元数据、元数据链路分析的管理,能够自动生成包括数据模型、数据质量、数据资源等在内的所有下游变更影响分析结果。基于勘探开发数据湖的数据治理变更影响分析,能够通过技术手段解决数据治理过程中数据采集、管理与应用的数据不一致性问题,提高数据总体质量。提出的数据治理变更影响分析方法有助于推动数据资产高效应用和价值发挥,提升业务分析和决策的效率与质量。With the advancement of digital transformation in oil and gas enterprises,the issues related to data collection,aggregation,management,processing,and application due to data changes are becoming increasingly prominent in the exploration and development field.This paper proposed a processing logic and methods to deal with change impact analysis for exploration and development data based on a set of meta-meta models,meta models,and metadata,which is abstracted from CNOOC exploration and development data lake platform.Based on the metadata management solution,the core data storage structures of the exploration and development data lake platform,such as data standard management and data model management,have been integrated.The management of meta models,metadata,and metadata link analysis can be achieved by using change impact analysis tools,and all downstream change impact analysis results,including data models,data quality,and data resources,can be automatically generated.The change impact analysis of data governance based on exploration and development data lakes can solve the problem of data inconsistency in data collection,management,and application during the data governance process through technical means and improve the overall quality of data.The proposed change impact analysis method of data governance in this article can help promote the efficient application and value realization of data assets and improve the efficiency and quality of business analysis and decision-making.
