ERA2000成像测井系统PLT动态链接库设计

Dynamic-link library design of PLT of ERA2000 imaging logging system.

动态链接库是成像测井系统软件的关键技术之一。文章分析了Windows动态链接库的组成结构、运行机制、加载方式。介绍了ERA2 0 0 0成像测井系统井下仪器采集处理软件动态添加的方法。阐述了PLT井下仪器动态链接库的设计思想 ,给出了关键的编程算法 ,并用VisualC 语言编程实现。现场测井使用表明 ,动态链接库具有提高成像测井系统软件的可靠性、可维护性、便于仪器的功能扩展等优点。

Dynamic-link library (DLL) is one of the key technologies of imaging logging system software. The constituded structure, the running mechanism and the loading mode of windows DLL are analyzed in this paper, and the dynamic-load method of downhole tool′s acquisition-processing software of ERA2000 imaging logging system is also introduced. In addition, the design idea and pivotal algorithm of the DLL of PLT downhole tool are described. Moreover, the DLL is realized by language Visual C. The practical logging operation shows that the DLL has the advantages of improved reliability, good maintainability and easy function expanding, etc..
