The Design And Development Of The Component For Vector Comprehensive Mud Logging Graphic

In the process of oil gas exploration and development,the comprehensive mud logging is widely used.The routine comprehensive mud logging drawing system is developed by using the custom program,the graphics quality is not high,and the system is poor.Vector comprehensive mud logging system has solved the problem of low graphics quality,but it has low efficiency.In order to draw the high quality comprehensive mud logging chart,and the system has good generality,this paper studies the vector comprehensive mud logging drawing module,which is based on the Framework4.0.NET platform and the multi module.Each module is designed and developed with the object oriented software design method.In order to facilitate the follow-up development and function development,combined with the application characteristics of the comprehensive mud logging map,the platform has nothing to do,and can be deployed on any Windows version of the platform.Finally,the application of Web technology can be realized by combining ActiveX technology,which can improve the application scope of the component.In this paper,the problem is solved by analyzing the existing problems of the logging tool,which is to improve the efficiency and the visual effect of the comprehensive mud logging,and meet the multi scene application of oil and gas exploration and development.Combined with the practical application of comprehensive mud logging,the construction target,functional requirements,performance requirements and operational requirements are summarized.According to the requirement analysis,using the method of vector graphics,and using the component model,the component of the drawing vector comprehensive mud logging unit is designed.Component to realize the user control,including the main vector map,multi-source database access and the vector diagram of online print connection function library and foundation class library.With the fast rendering of the mud logging composite chart,the control uses the double buffer mechanism and the user visible region to draw the optimized processing method.Curve modification and data storage,easy to modify the geological data.The security and the development efficiency of the components are improved by using all the reusable libraries.Finally,through the application of desktop applications,browser release application,multi-source heterogeneous data mapping and the overall functional testing,the functional integrity of the components and the availability of.
