| 摘 要： | 在进行地球物理测井数据处理或解释软件开发时,只有知道所处理的测井数据的格式,才能正确地进行读取、格式转换、数据处理以及绘图等工作。在对ECLIPS 5700数控测井系统XTF文件格式分析的基础上,基于内存映射文件技术,采用面向对象的方法创建了XTF文件数据读取类,实现了大数据量XTF文件数据的快速读取,也可为其它格式测井数据的格式转换和数据处理提供技术参考。

| Abstract: | In the course of processing geophysical well logging data or developing well logging interpretation software, it is important to know the format of well logging data file. In understanding the format of well logging data to be processed, much work can be done, such as reading data, transforming data format, processing data and plotting. On the basis of analyzing XTF file format of ECLIPS 5700 well logging system, a class of reading XTF format data was built with the object-oriented method based on the memory mapping file technique. This technique realizes fast reading of XTF format file with mass data and also provides the technical reference for format transformation and data processing of other well logging data formats. |
