Research And Development Of Logging Data Management Platform Based On EPDM

Digital oilfield in recent years of the development process, with the data center in logging data management obtained the popularization and application, new data models be improved and perfected, the logging data management system based on business driven since it was put into use up to now, after it’s in the exploration, development and production management in the application of continuous improvement and perfection, has stable operation, can provide reliable support for data center logging data management. But with data center in the operation of the continuous in-depth, its technology application and management mechanism generally flawed, unable to reach the advanced level of technology in the industry, the management mechanism still remain in the decentralized system, the present situation, has been difficult to adapt to large system construction and operation maintenance management and development needs. So, in order to realize the data center logging data management and service level of a substantial upgrade, need to propose a complete, scientific data management mode and the corresponding technical support.In this paper, through the study on the control of data quality standards, and the constraint theory of data quality, on the basis of Chinese petro unified EPDM data model, construction of logging data management platform with EPDM as the core. Through research problems of center database, analyze and propose solutions to build the data management center architecture. Study on the related theory of data element model of quality control, put forward the assessment method of data quality, design and realize four element models. They are data dictionary element model, rights management element model, data quality constraint element model, assessment algorithm element model. And then through the detailed needs analysis, organize business process and data flow, divided into four functional modules, make overall plan for application platform.Finally, this paper gives the realization of the logging data management platform based on EPDM, the platform has been put into use. Part of the data sheet in the database have been do quality assessment, the operation results show that the logging data management platform based on EPDM is stable and efficient operation.
