The Design And Research Of Oil Field Exploration Information Systems Based On GIS

GIS as computer science, geography, surveying, cartography and other subjects in a comprehensive and Edge disciplines, its development and other subjects closely related to the development. GIS technology has developed rapidly in recent years, geographic information systems in the geospatial data management, in a comprehensive analysis and evaluation of the simulation forecast reflects the GIS technology to produce unlimited life easier.This article from the GIS System, Applications, summarized characteristics of summing up of a number of GIS application, a omprehensive and systematic exposition of the GIS in oil exploration and development of data management. Oil exploration and development targeted at building the database, data exploration and development through the establishment of model-based data system; hierarchical system introduced on how to spread the bottom of the heterogeneous database data source information, effectively integrated, and application management. ARCGIS to secondary development platform, and other technology as the core, system architecture, data integration, to extend the application functionality, introduced for oil field exploration and development of applications based on Web GIS solutions.Data from the main library system design and model relations in areas such as data on the system data main library building in the basic process, and in accordance with the oil exploration, reservoir evaluation, field development phase of the 3 major production activities, a total of 10 basic types of entities, the combination of exploration The development of professional categories, the definition of exploration and development of the relationship between data tables, data attributes of the code. The database system construction and application of data integration and data all around the room for 10 basic types of entities carried out by the database, information systems and geospatial databases and combine the exploration and development of the database, may at any time extraction of relevant data. Systems designed in accordance with the framework of the data source layer, the main data center library, data integration, data interfaces, the application of the release of the five-level system to meet the various functions of the design; data through the database of various types of database system is called a tool to achieve data From the master database data preparation area :data storage area, the final outcome of the research data and output to the main database for the purpose of preservation.GIS system platform using ESRI's ArcGIS 9.1 geographic information system field as a unified platform for GIS software. Selected ArcGIS family of products, covering from the spatial database engine (ArcSDE) to the desktop GIS applications, and ArcGIS Server application server, and so on and so on, to make full use of ESRI in the GIS industry, advanced and comprehensive technology to meet the oil fields of geographic information System.System construction is completed, will provide users with a complete business for the use of a series of hardware and software products. Users of the system interface to receive information service system. In accordance with the results of the structural design of the system, the completion of the project will be submitted to the three types of applications, including system-level user-oriented system to maintain and safeguard data management tool for enterprise networks based on C / S structure of the products and desktop applications based on B / S The framework for users inside and outside the network of Web applications.System of a number of possible levels of error or fault conditions; such as: the physical level, system-level platform and application-level description of the classification, and so on. For each level of error or fault, and may be a number of specific types of fault systems proposed by the output and processing methods.For each client's data entry functions will be carried out relatively strict restrictions to prevent the illegal importation of data. Used. Net's structured exception handling mechanism, every time a mistake to give the wrong information and detailed guidance for the user to change. The method is the use of managed code TRY CATCH structure makes the procedure to minimize the risk of collapse.Through structured exception handling mechanism can be pointed out that the visual system errors through direct dialog news show produced by the news exception handling, and can cause the wrong location and for system maintenance personnel to carry out inspections accordingly. By building a multi-level system of data collection, audit, issued by the professional field data updates to maintain a mechanism to achieve the professional field of data in a timely and accurate updates storage to meet the related field of professional applications; focused on building through the sharing of specialized oil field Spatial Database, the realization of the comprehensive utilization of GIS data; data sharing and exchange of technology, systems integration and technology resources to achieve automatic search, the allocation of resources, data updates, information utilization, and other functions to support decision-making; used to optimize deployment of cluster server Technology, reasonable and efficient platform for the entire operation.GIS application has given us new techniques and ideas, we should seize the opportunity to use GIS technology to develop and improve the application of the oil fields in the oil exploration and development of geographic information systems for management, Analysis of a large number of exploration and development of information graphics data for oil field exploration and development to provide a scientific basis for decision-making.
