Design And Implementation Of Vector Mudlogging Diagram System

Vector format mudlogging diagram system can deal with the visualization of all kinds of logging data, which also can the turn the data in database into logging diagram automatically and quickly. The system can help us analysis the data after the diagram generated, overcome the drawbacks of traditional drawing methods, fully use the advantages of vectorization logging diagram, and improve the level of information and visualization of logging data.Firstly, a subsystem of vector symbols drawing is designed and implemented on the.NET platform. It has achieved enough complete and perfect that all symbols from the subsystems meet the standard and criterion of logging industry. The subsystem defines a series of graphic primitive classes, which support eight basic graphics illustration including line, rectangle etc. The subsystem defines the methods of vector graphics illustrating, graphics operating and editing of the graphics properties. Vector graphic symbols are saved as SVG vector format.We implement the vector format mudlogging diagram illustration system based on theGDI+ libraries of the.Net platform. It is a browsing project of the logging data on C/S architecture. The main function of the system is making complexing logging data present in a graphical way, and can modify data properties in realtime, making it easier for users to browse, modify and analysis. Mudlogging includes head part and plot part. Through the realization of the function of loading chart templates, it can get rid of redrawing of the same part in the diagram. According to the results of querying database, the data curve, scale data, vector symbols data are drawn respectively with calling the subsystem of symbol library data. We realize graphic elements vectorization with XML technology, which is meeted in the standard of logging engineering.
