Abstract

The invention discloses a map superposition-based target exploration stratum exposure point navigation method and a map superposition-based target exploration stratum exposure point navigation system. The method comprises the following steps: acquiring an electronic geological map of a region where a target exploration stratum is located; acquiring an electronic standard map of a region where the target exploration stratum is located; superposing the electronic geological map and the electronic standard map to obtain an electronic superposed map; obtaining the position of a dew point of a target exploration stratum in the geological map layer of the electronic overlay map; generating a navigation route of the exposure point of the target exploration stratum according to the position of the exposure point of the target exploration stratum; and displaying the navigation route of the exposure point of the target exploration stratum on a standard map layer of the electronic overlay map. The system provided by the invention comprises functional modules for correspondingly realizing the steps of each method. According to the invention, the problem of low efficiency of the geological exploration link of oil and gas field exploration caused by the existing on-site searching method of the exposure point of the target exploration stratum can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of stratum surveying, and more particularly relates to a method and system for navigating outcropping points of strata for target surveying based on map superposition. Background technique [0002] The exploration and development process of oil and gas fields mainly includes geological survey, geophysical prospecting, drilling, mud logging, logging, cementing, well completion, perforation, oil production, well workover, incremental production, transportation and processing, etc. These links are closely linked One ring, interdependent and inseparable. [0003] Among them, geological exploration is that petroleum prospectors use geological knowledge and carry simple tools such as compass and hammer to directly observe and study the bottom layer and rocks exposed on the ground in the field, understand the sedimentary strata and structural characteristics, and collect all geological data for Find out the favora...
