Embodiment 1

[0027] Example 1, such as figure 1 (1) First apply remote sensing technology and remote sensing satellite data, through image information extraction, establish interpretation signs related to geothermal resources, conduct field verification, and quickly and accurately interpret the formation, rock mass, and structure of geothermal resources in the target area Translation, preliminarily delineate the geothermal anomaly area;

[0028] (2) Further carry out field work of geothermal geological survey, investigate whether there are geothermal wells and their distribution in abnormal areas, select suitable geothermal wells for geothermal survey, and further analyze the distribution law of geothermal field. Carry out large-scale surveys of areas where geothermal fields may be formed with high geothermal values, and analyze several major elements that form geothermal fields: heat source, water source, and channel;

[0029] (3) Channel analysis: Based on the analysis results of step (...

Abstract

The present invention relates to a structural trap type weakly open layered karst heat storage geothermal field prospecting method, which includes the following steps: (1) Firstly, using remote sensing technology and remote sensing satellite data, through image information extraction, to establish a geothermal resource-related Interpret the signs, conduct field verification, quickly and accurately interpret the stratum, rock mass, and structure of the geothermal resources in the target area, and initially delineate the geothermal anomaly area; Without geothermal wells and their distribution, select suitable geothermal wells for geothermal surveying, and further analyze the distribution of geothermal fields; conduct large-scale surveys of areas with high geothermal values ​​that may form geothermal fields, and analyze several major elements that form geothermal fields: Heat source, water source, channel; (4) Model establishment (5) Discrimination of geothermal enrichment area.

Description

technical field [0001] The invention belongs to the technical field of geothermal prospecting, and in particular relates to a method for prospecting a structurally closed type weakly open layered karst heat storage geothermal field. Background technique [0002] Mineralization has a close genetic relationship with geological tectonics and the formation and evolution of regional structural types. 1) Geological structure has control over the formation of ore deposits. Large-scale fault structures and fold structures directly control the formation and distribution of ore deposits (such as hydrothermal deposits), and they provide favorable migration channels and accumulation sites for ore-forming materials. 2) The emergence of geological structures promoted the re-enrichment and re-embedding of pre-formed ore deposits (ore bodies). The combination of tectonic stress and other geological factors (thermodynamics, geological fluids, etc.) endows the initially enriched ore-forming...
