| Daqing oil field has been developed and constructed for 50 years, accumulated a large amount of original production data, established a relatively comprehensive database system, the data is a valuable asset. The purpose of the database-building is not just built, but to use. In recent years, the information technology mainly fragmented, repetitive collection, issues such as ambiguity, the lower the degree of information sharing, "information island" is a serious problem. To this end, we adopted the practice of software development for many years, combined with domestic and foreign software companies and successful case studies and analysis, established consistent with the Daqing oil field production, management of the business logic, set up a business-driven data-driven inquiry, analysis integrated application platform, in line with the oil fields of the production management needsIn this paper, through the data warehouse, analysis the problems of the Daqing Oilfield Construction based on data mining technology and other related theories, according to the Daqing oil field's existing data sources, proposed the scheme of "digital underground system" based on data warehouse technology , study the the concept of data warehouse model and logic model in development. The system based on the development of thinking to meet the production plants, mines, teams at all levels of demand for data applications, on the one hand to provide an effective means of data retrieval, on the other hand, to meet the business logic to provide comparative analysis of the special focus on practicality.Data resource is the "digital underground" the cornerstone of the information platform. Accurat, timely, high-quality data resources make sure the practicality of the system and the basis of reliability. To this end, we set up a database of the project team to integrate at different levels of data and develop an effective program to load the data, so that a variety of dynamic and timely information can be loaded, and some exterior production units can be provided data collection and collation. So much more comprehensive data resources can be established and a number of standard dimension table are created, such as the date dimension (year, quarter, month, old, weeks, days, etc.) well-dimension (old well, last revised well, expanded edge well, etc.) mine force dimension, well station dimension (joint station, transit station, measurement station) block dimension (oil field, block, module, cell block, etc.), as well as other forms of peacekeeping, such as measure dimension, exploited oil dimension.shutted well reason dimension. When these dimensional tables associated with the fact table , the data can be browsered from all kinds of perspectie in accordance with the table dimension. Making the oil field development data model of online analysis and data model stored in multi-dimensional aggregates stores the relationship table as in the basic table. Online analysis tools through interface and data warehouse obtain data collection and complete sliced data, rotation, drill and so on.The dynamic analysis in field is still mainly based on manual analysis, and the method costs more time and requires a longer period of data preparation.But application software is mainly based on statistics and the comparison method.Artificial intelligence technology is applied to the remaining oil distribution , derrick machine identification, the analysis of well logs, but the use of wells analysis is less.In this paper, according to a preliminary study of neural network technology, the delay of the relation between affusion and explored time isconfirm based on test injection profile, output profile, calculated stratified layer of water injection and pressure, the relationship between explored liquid and liquid water content,regression analysis and so on and the neural and analytic network model which is related to the layer neural network model and the connectivity is established, which make an impact of oil production in the analysis of factors associated with neural network simulation of the actual data change.Metadata management is the idea of managing the data warehouse and achieve the unified maintenance and management of the oil field data development and the relevant procedure data. Some designs such as content design, structure design, code design and program and some processes such as meta-data management tools.data extraction, validation and integration are made for metadata. The main principle is that all resources including data on different servers and different types of standard table, constraint table are unified management and maintenance.At the same time ,putting forward the WEBGIS middle component design schema basing on the MapXtreme. WEBGIS middle component screens the complex of OS.This makes the programmer to facing a singly and unified development enviorment.reducing the complex of program design.Adopting the WEBGIS middle component to generating the graph of oil field resolves some questions such as accessing the distributed and multi-datasource,dynamic generation of geology graph ,distribution and query.The system is base on the standard of oil field development database,obey the mind of business driver.adopt "factory" design mode and distribution system method, carry out separation of business layer and mean layer, comprehensive application of the oil extraction factory oil-field development, oil extraction engineering and ground engineering information,and carry out a single clarification of the user and the integration of the data resources, and according to management work of the oil extraction brigade, mineral and factory, It provide the exellent application platform for production, development and the manager .demonstration the means is vivid of comprehensive the information apply terrace and satisfy business personnel's production control and contrast analysis, particularly item function requests, such as information statistics and information inde.The system mainly includes main function as follows:(1) Establishing a unified user authentication program, to manage and distribute the functions of the various application systems(2) Using WEBGIS technology, to realize the well, the transit points and measurement Workshop's navigation and accessing relevant information(3) Realizing reservoir, sedimentary facies maps, contour map, and AutoCAD graphics data storage, using high-level language interface to read and write and complete the exchange of graphics and text, through the provision of database connection and parameters to achieve the data's transmission extracting, generating AUTOCAD command format, generation of graphics required to complete the parametric drawing automatic.(4) Realizing personalized settings for different users ,improving the flexibility of the system to meet the customers' changing business needs(5) Establishing distributed data management platform based on Metadata-based, realizing resources collation and quality control of existing data, to achieve the integration of data resources(6) The establishment collects according to the data of Web method, the statement make to order system.(7) Establishing a system-driven application platform for integration different applications, improving system's reuse and to avoid duplication of development caused by people, financial, and material waste.The system Provide a fast and efficient production analytical tools for technical management staff, the application's using and construction have met the different demands of oil fields' management, and promoted database's building, this system will improve efficiency for the oil field and increase the economic benefits ,the system have a good prospects in the oil field. |
