Embodiment Construction

[0028] On the basis of fully digesting and understanding the mainstream data file formats in the domestic and foreign well logging industry, the present invention starts with the logical structure and designs the logical structure of the well logging data files in combination with the needs of well logging services.

[0029] figure 1 The overall structure of the GDS (GeoScope Data System) real-time logging data file of the present invention is shown. From figure 1 It can be seen that each GDS real-time logging data file includes a file header and multiple logical files, and each logical file includes multiple data objects, and each data object includes a data object header and data object content.

[0030] Logic files are mainly used to classify and manage data objects. figure 2 The logical structure of the logical file reflecting the GDS real-time logging data file.

[0031] From figure 2 It can be seen that each logical file is composed of a logical file object heade...

Abstract

The invention provides a GDS real-time well logging data file which comprises a file header and a plurality of logical files, wherein each logical file comprises a plurality of data objects and each data object comprises a data object header and the content of the data object.

Description

technical field [0001] The invention relates to a GDS real-time logging data file, in particular to the logic design of the GDS real-time logging data file and its access interface class library. Background technique [0002] Logging acquisition software needs to record a large amount of real-time logging data in real time, including well site information, engineering information, logging parameters, real-time acquisition data and so on. Since well logging acquisition software has strict requirements on real-time data files in terms of data type, data volume, response time, post-display processing, standardization, and scalability, most logging data file formats in the industry currently have one or the other limitations. [0003] Table 1 lists the main logging data file formats in the logging industry, and gives a basic evaluation of each data format: [0004] serial number format name factory Advantage limitation 1 DLIS Schlumberger Standardize...
