2results about How to "Reduce identification costs" patented technology

This invention relates to the field of lithology identification methods, specifically a method and apparatus for identifying lithology in tight gravelly sandstone reservoirs through well logging. The method includes: determining key sensitive parameters for different lithologies within a target tight gravelly sandstone reservoir; establishing Q-models for specific lithologies and other lithologies based on the key sensitive parameters; identifying samples of specific lithologies based on the Q-models for those lithologies; and identifying samples of other lithologies based on the Q-models for those lithologies. This invention achieves precise identification and quantitative characterization of lithology in tight gravelly sandstone reservoirs, providing an intuitive and effective reference for subsequent calculations of tight reservoir parameters. It enables the identification and characterization of lithology using conventional well logging data, significantly improving the efficiency and reducing the cost of well logging interpretation.

The application provides an element recognition point data processing method and device, electronic equipment and a storage medium, relates to the technical field of electronic maps, can be applied to various scenes such as cloud technology, artificial intelligence, intelligent transportation and auxiliary driving, and the method comprises the following steps: receiving recognition point data of a road image reported by a terminal; performing initial aggregation processing on the recognition point data based on a time sequence to obtain a plurality of recognition point sequences; extracting a recognition point subsequence corresponding to an element label of at least one element type from each recognition point sequence of the plurality of recognition point sequences; determining a recognition target difference and an image time difference between two adjacent recognition point data in the recognition point subsequence; and performing same element aggregation on the recognition point data in the recognition point subsequence according to the recognition target difference, the image time difference and an element similarity condition to obtain a target sequence segment corresponding to the recognition point subsequence. The application can ensure the coverage and integrity of road elements and reduce the cost of the terminal.
