Problems solved by technology
[0007] However, in the process of realizing the present invention, the inventor found that the defect of the prior art is that the logging curve of a logging well is stored in a data file, and the method of searching through the file header is not convenient for data exchange and sharing and network applications; by analyzing the data file for retrieval, it is necessary to locate the logging file and then analyze the logging file to obtain the target logging curve data. The execution efficiency is low and the retrieval speed is slow

Embodiment Construction
[0028] In order to make the object, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.
[0029] An embodiment of the present invention provides a method for retrieving well logging curve data. Such as figure 1 As shown, the method includes:
[0030] In step 101, the data server acquires well logging curve data, and decomposes header data information, measurement data and curve data body to form the well logging curve data.
[0031] In this embodiment, the logging curve data can be collected by the acquisition device first, and the header data information and the logging data of the logging curve data can be generated at the same time. It can be realized by adopting the existi...

The invention relates to a search method and device of borehole log data. The method comprises the following steps: obtaining borehole log data by a data server, decomposing the borehole log data to form the head data information, the times measuring data and the curve data volume of the borehole log data; storing the head data information, the times measuring data and the curve data volume of the borehole log data to a corresponding data structure of a database; receiving the search request of the borehole log data to be searched by the data server; according to the head data information corresponding to the borehole log data, calculating the starting position and the final position of the borehole log data in the data volume; and according to the starting position and the final position, reading or writing in the borehole log data from the data volume. By the embodiment of the invention, the position of the required borehole log data can be located without analyzing a data file and search efficiency is high; in addition, the invention is convenient to store and maintain the borehole log data and is convenient to exchange and share data and apply the network.
Description
technical field [0001] The invention relates to the field of well logging technology, in particular to a retrieval method and device for well logging curve data. Background technique [0002] Logging technology is an important qualitative and quantitative evaluation method in the process of oil and gas exploration and development. Various logging curve data collected and processed in the logging business reflect various physical and chemical properties, stratum structure and wellbore geometry of the underground formation. characteristic. Well logging curves are usually generated and processed in batches in units of well logging times. A well logging time includes multiple original curve data in the measurement batch and even the logging data formed after professional processing and interpretation. These logging data need to be properly preserved and quickly queried, located, read and written to support the development of follow-up services. [0003] There are two types of ...
