Research On The Mechanism Of Heterogeneous Petroleum Information Service Platform Based On Three-Tier B/S Architecture

In this paper, according to the overall requirement of the exploitation system of the Limited Liability Company of Daqing oil field, the network administration of regular item of daily office work in exploitation system,the resource sharing of exploitation data,the management of the skill application tools of exploitation and the special technology information based on web were implemented, using the resources of existing computer network,exploitation data base and achievement data base.With the user being limited by role and right, flow of manual work was entirety simulated by computer. Application server accept the document disposal request sent by client-side, automatically accomplish the management of deedbox, including deedbox application.document submission,document check and approve,document transmit.The data manipulation mode constructed on Agent technology and three tier system was used to the inquiry of all-around information of borehole logging curves with the combination of Agent technology and three tier construction. User can transmit data,update data,inquiry data conveniently without knowing the data's geographic location and curve type, meanwhile, this mode shields user from dealing data directly, thereby reduce the difficulty in data processing.Constructing subsystem of exploitation geology map working platform on Delphi and GIS (ComGIS) technology was studied. Through Active Control developed on Delphi, the data used to draw map are updated and transmited to MapInfo where they are modified realtimely, then issued on Asp+MapXtreme+IIs in gst format(organized by the geomanager tool of MapXtreme).This paper consists of six chapters. At first, the signification and necessity for developing this system was stated and a brief introduction of research background, the role and difficulty of this paper were given. With the comparison of two common used structures C/S and B/S, the system structure in this paper was introduced in chapter 2. The general design of the system was in Chapter 3, a total planning was given, and the safety system was studied and discussed. From chapter 4 to 6, the analyzing,design and realization of each component of the exploitation information service platform were discussed respetively.
