Application of comprehensive geophysical prospecting methods in the exploration of medium and deep geothermal hot springs in 2024
With the continuous progress of science and technology, geophysical exploration (referred to as geophysical prospecting) technology plays an increasingly important role in geothermal resource exploration. Especially in the field of medium and deep geothermal hot spring exploration, the application of comprehensive geophysical prospecting methods has become a key means to improve exploration efficiency and reduce costs.
1. Overview of comprehensive geophysical prospecting methods.
The comprehensive geophysical prospecting method refers to the organic combination of a variety of geophysical exploration technologies to form a comprehensive exploration system, so as to achieve efficient and accurate exploration of geothermal hot spring resources. These techniques include, but are not limited to: resistivity method, magnetic method, gravity method, ** method, electromagnetic method, etc. Each method has its own unique detection depth and resolution, and through comprehensive application, it can achieve all-round and multi-angle detection of geothermal hot springs.
2. Application of comprehensive geophysical prospecting method in the exploration of medium and deep geothermal hot springs.
Determination of geothermal anomaly areas: Through resistivity and electromagnetic methods, the resistivity and electromagnetic field distribution of the underground can be accurately detected, so as to determine the location and extent of geothermal anomaly areas.
Characterizing geothermal structures: Gravity and magnetic methods can help researchers understand the density and magnetic distribution of the subsurface, further characterize geothermal structures, and provide guidance for subsequent drilling efforts.
Evaluation of geothermal resource potential: Through the ** method, the underground rock structure and fault distribution can be detected, and the reserves and exploitation potential of geothermal resources can be evaluated.
3. Advantages and challenges of integrated geophysical prospecting methods.
Advantages: High efficiency: multiple methods are operated in parallel, which greatly shortens the exploration cycle.
High precision: A variety of methods verify each other, which improves the reliability of the survey results.
Low cost: Compared with traditional drilling methods, geophysical prospecting methods have lower costs.
Challenge: Technical complexity: Specialized technicians are required for operation and data analysis.
Environmental impact: Some geophysical prospecting methods may have a certain impact on the environment, and the operation area needs to be reasonably planned.
Fourth, the future outlook.
With the continuous progress of technology and the reduction of cost, the application of comprehensive geophysical prospecting methods in the exploration of medium and deep geothermal hot springs will be more extensive. In the future, we look forward to seeing more innovative geophysical technologies and methods to provide more powerful support for the exploration and development of geothermal resources." At the same time, it is also necessary to strengthen environmental awareness and ensure that the impact of exploration activities on the environment is minimized.
