Problems solved by technology

However, in the process of generating XRMI images, these software require a large amount of manual judgment and data analysis, and at the same time need to manually input various parameters, which makes the operation complicated
Moreover, for non-professional logging interpreters, it is difficult to process and generate an electrical imaging map

Abstract

The invention discloses an XRMI (Extended Range Micro-resistivity Imager) electric imaging image generation method. The method comprises the following steps that: (1) the automatic selection judgment,loading and information identification of XRMI electrical imaging measurement data are performed; (2) automatic statistical analysis judgment and data preprocessing are performed on the quality performance of the automatically selected and loaded data in the step (1); and (3) automatic image calibration and processing are performed according to preprocessed data, and a display image is automatically generated according to a calibration and processing result. The method is simple to operate and can automatically decode, encode and identify XRMI electric imaging logging data. According to the method, technicians only need to load the electric imaging data, software will automatically perform data quality statistical analysis, data preprocessing, image processing, image display, and manual filling of various parameters is not required, the error probability of manual operation can be decreased, and therefore, non-well logging interpretation professionals can also quickly obtain the dynamic and static electrical imaging effect pictures of XRMI electrical imaging.

Description

Technical field [0001] The present invention relates to the technical field of geophysical petroleum geological logging, survey and data analysis, in particular to the automatic generation and processing method of the image used for processing XRMI electrical imaging data to obtain the image representation of the geological rock formation, that is, the automatic XRMI electrical imaging image Generation method Background technique [0002] Electrical imaging logging is an advanced logging technology with high resolution. It can provide a wealth of information about the borehole wall and around the borehole. It can not only visually identify the bottom interface, fractures and qualitatively from the logging images. Structural morphology, and quantitative processing and analysis of logging images can be made through image processing methods, and parameters such as formation interfaces and production conditions can be extracted. Electrical imaging logging has been widely used in com...
