Description

Technical Field

[0001] This invention relates to the field of well logging technology, and more specifically, to a method and system for converting HDS data to DLIS format for well logging data indexed by HDS. Background Technology

[0002] HDLOG (Huanding Company Logging Acquisition and Processing Platform) logging software is a logging acquisition platform developed by the applicant. The logging software saves logging data in HDS (Huanding Company Logging File Data Format). After the logging operation is completed, the logging data is handed over to the oilfield for interpretation, which requires the logging data format supported by the oilfield interpretation system.

[0003] The DLIS data format is the same as that used by Schlumberger's logging software abroad, and can be directly imported into Schlumberger's Techlog logging interpretation platform. However, data format conversion is a problem that HDLOG needs to solve in order to interact with the Techlog logging interpretation platform used in some domestic oilfields.

[0004] Previously, the conversion of HDLOG logging data format involved the logging field engineer converting the HDS data format to LAS data format, and then using third-party software to convert the LAS data format to DLIS format. (See attached diagram.) Figure 1 As shown, HDS format cannot be directly converted to DLIS format; third-party software such as Forward.net is required for conversion.

[0005] Existing methods for converting well logging data formats are time-consuming and labor-intensive, and may lose some file information during the conversion process, such as file header information and curve descriptions. Summary of the Invention

[0006] Therefore, the purpose of this invention is to propose a method for converting well logging data from HDS to DLIS format, which can directly convert HDS format well logging data files into DLIS format and quickly read the converted file data, thereby saving time for field engineers and improving the efficiency of data format conversion.

[0007] This invention provides a method for converting well logging data from HDS to DLIS format, comprising the following steps:

[0008] S1. By using memory-mapped files, a region of the process address space is created when reading HDS format source files, and the physical memory where the HDS file that already exists on the disk is located is submitted to the region of the process address space.

[0009] S2. Map the HDS file on the disk to the process address space and establish a data index;

[0010] This characteristic of file memory mapping is very suitable for managing large files;

[0011] This eliminates the need for I / O operations when processing HDS files stored on disk, enabling rapid reading and conversion of file data. It significantly improves the efficiency of data indexing and repackaging when dealing with large amounts of data, playing a crucial role in this process.

[0012] S3. Using object-oriented programming, construct a DLIS converter object to perform DLIS format conversion on the HDS file.

[0013] Further, the method for mapping the HDS file on the disk to the process address space in step S2 includes:

[0014] File mapping establishes a mapping association between all or part of the contents of an HDS file on the disk and a region of the created process address space, allowing direct access to the mapped HDS file without performing file I / O operations or buffering the HDS file contents.

[0015] Furthermore, the method for performing DLIS format conversion on the HDS file in step S3 includes:

[0016] Using object-oriented design, DLIS file class, HDS file class, and DLIS converter class are established, and related attributes such as file header, output curve list, time depth data volume, and curve data index are encapsulated in the relevant classes.

[0017] In object-oriented programming, the most basic unit of encapsulation is the object. The most basic goal that encapsulation in object-oriented design technology needs to achieve is to enable the related components of the software structure to achieve the "optimal state" of "high cohesion and low coupling".

[0018] The structure of the DLIS converter class, the format file conversion process, and the page display are shown in the attached figure. Figure 3 As shown:

[0019] Furthermore, the method for performing DLIS format conversion on the HDS file in step S3 further includes:

[0020] Added methods for reading HDS format files, creating HDS data indexes, converting DLIS file headers, and repackaging data.

[0021] The DLIS converter object constructed using the method of this invention can easily and quickly achieve file format conversion. Developers only need to perform conversion-related operations through the external channel, which simplifies the steps of digital format conversion operations and improves the efficiency of data format conversion.

[0022] Furthermore, step S3, which converts the HDS file to DLIS format for direct conversion, is implemented using a WinForms application developed in C#.

[0023] This invention also provides a well logging data HDS to DLIS format conversion system, which performs the well logging data HDS to DLIS format conversion method as described above, including:

[0024] The process address space creation module is used to create a region of the process address space when reading HDS format source files through memory-mapped files, and to submit the physical storage where the HDS file already exists on the disk is located to the region of the process address space.

[0025] File mapping module: used to map HDS files on the disk to the process address space and establish a data index;

[0026] Data format conversion module: Using object-oriented programming, a DLIS converter object is constructed to perform DLIS format conversion on the HDS file.

[0027] The present invention also provides a computer-readable storage medium having a computer program stored thereon, wherein the program, when executed by a processor, implements the steps of the well logging data HDS to DLIS format conversion method as described above, and the well logging data HDS to DLIS format conversion system as described above.

[0030] The HDS to DLIS format conversion method of this invention can quickly read and convert file data, and directly convert HDS format well logging data files into DLIS data format, which greatly saves the time of field engineers and improves the efficiency of data format conversion.
