Research And Implement Of Oil Field WebGIS Based On SOA

Oil field GIS data is distributed widely, and data acquisition is not completed at one time only, but is completed intermittently, continuously and dynamically。It is carried out for data acquisition, primary data process and data storage in remote web sites, and many information retrieve, information extraction, information analysis and information acquisition are required in the distributed network environment. Nevertheless, the traditional centralized GIS can not solve these issues of GIS model and data sharing in the network, only distributed GIS can solve sharing and operation of geographic information data located different sites in network, and solve heterogeneous data sharing and computational complexity.In this paper, some key technologies are researched in-depth,such as WebGIS, web services, SOA, SVG, Ajax and other related technologies, a service-oriented GIS network architecture is proposed,SVG is used for map display, Web services of SOA are created by DotNET, deployed and published by using standard UDDI and WSDL, which is a platform of comprehensive information display, operation and query of geographic information.The platform implements the model construction of distributed environment of WebGIS and the sharing of the multi-source and heterogeneous space data of GIS.According to the practical requirements of oilfield, the data query platform of oilfield geographic information visualization base on SOA is designed, which implements the integrated query of data sharing that distributed ground engineering database, exploration and development database in the various production plants in the field and graphical operation based on SVG, and solves the problem of slow loading of SVG map for a large amount of data. By using the function of GIS navigation in the platform, the users in the oil field development and production can obtain conveniently and quickly integrated information and work cooperatively, and provides effective information technology support for the development and management of oil and gas field.
