The Study Of Decision Support System Of Dynamic Management In Oil Development

The Oil field development with the characteristics of high input, high output, high-risk and irreversibility, scientific decision-making is especially important, and information is the basis of scientific decision-making.How to make full use of various information resources to Auxiliary oil analysts and management personnel for efficient dynamic analysis and decision-making for Raising the level of oilfield development is an currently important research topic.The Project of"Develop dynamic management decision system"is based on Development of static and dynamic database of Eight plant of Daqing Oil Production with the processing results of A2 application integration systems and other sophisticated applications and data warehouse technology and the concept of expert system Provide users with various types of oil production-line real-time production management issues warning, and Choice Decision Support regional block measures , Auxiliary construction plan generated, Integration of various types of information on-line access and other functions. The dynamic management of oil development involves oil production analysis and design of development measures, regulation of recovery schemes and other manifold works. Production decision plays a very important role in improving production and efficient exploitation. Therefore, it is important to use information technology to do assisting strategic work of oil development dynamic management.The development of the dynamic management strategic supportive system is studied in major, including the design of assisting strategic supportive system model, the establishment of assisting strategic knowledge framework and the realization of assisting application system and other main parts. The assisting strategic supportive system model is the logical organization of system development, the design philosophy of system model is summarized according to the system analysis, the framework of intelligent application system and the design of knowledge model. The oil assisting strategic supportive framework is also organized. Based on that, the analysis of relational data is realized to support reasoning and deducing of supportive assisting knowledge.。According to the model building of basic oil production knowledge, the design of knowledge management system and other respects, the knowledge management framework of oil development is studied. The production performance is considered from knowledge management level. Production wells are distinguished from production range. Management framework of single well knowledge and block knowledge is designed. And production information is compared and analyzed according to value type, fluctuate type and other respects. Based on the research of assisting strategic model and knowledge driving framework, the development of various dynamic management assisting strategic application systems is finished in oil field. The theory and the framework are applied in actual production. The optimizing of producing building measures in oil field, the assisting design of producing building measures in oil field, the early warnings of production problem, the management of early warning data, the analysis of problem wells, the exhibition of production present figures, the exhibition of connection fence diagrams and other dynamic production assisting strategic application systems.The project implemented based on integrated resource management data warehouse platform, data warehouse database integration A2 , Development of the database, Database connectivity, Dynamic program library, Sedimentary facieses Library, Basic Knowledge and the information database of early warning rule basic. To Operate the system for providing reliable support and Complete rules that can be customized expert system support environment, Combination of expert system theory and information systems development demand, Designed to support data relationship rules of inference customizable framework for expert system design and Based on the architecture for the dynamic development of oilfield Decision Support System Data obtained by analyzing the relationship between the views of decision-making and it is play an important role in the dynamic development and design. Complete expert system supporting decision applications, based on the expert system support environment for field staff to provide early warning function of production of various indicators, To achieve various production data integration and visualization of early warning information display. With the exception for the production of selected wells, automatic query information, staff information available to Optimization of auxiliary, Adjusted for water injection, fracturing, water control, fill holes and other measures of work processes, support staff adjustment program, and generate reports supporting.
