Description

Technical Field

[0001] This invention relates to the field of geophysical exploration, and more specifically, to a method, apparatus, electronic device, and medium for predicting the direction of tectonic stress. Background Technology

[0002] Tectonic stress is the reflection of internal stress on the Earth's surface and is one of the main factors causing earthquakes, tectonic movements, and various geological disasters. Therefore, research on tectonic stress has been highly valued both domestically and internationally, resulting in some significant progress and achievements.

[0003] Currently, research on tectonic stress both domestically and internationally mainly focuses on the following aspects:

[0004] Geodynamics: Geodynamics is the study of the movement and evolution of matter within the Earth, including the lithosphere, asthenosphere, and outer core. In-depth research into geodynamics allows for a better understanding of the stress distribution and evolution within the Earth, and consequently, the formation and evolution of tectonic stresses.

[0005] Seismic activity: Earthquakes are one of the most important manifestations of tectonic stress. By studying seismic activity, we can gain a deeper understanding of the mechanisms and patterns of earthquakes, and further analyze the distribution and changes of tectonic stress.

[0006] Structural geomorphology: Structural geomorphology is the study of the structural landforms of the Earth's surface. By studying the structural landforms of the Earth's surface, we can understand the distribution and evolution of stress on the Earth's surface, and further analyze the distribution and changes of tectonic stress.

[0007] Geological exploration: Geological exploration is an important means of obtaining information and data about the Earth's interior. Through geological exploration, a large amount of geological data and information can be obtained, which can then be used to analyze the distribution and evolution of tectonic stress.

[0008] In general, research on tectonic stress has made some progress and achieved certain results both domestically and internationally, but many issues still need further research and exploration.

[0009] There are two approaches to determining tectonic stress. One is through seismic analysis. The advantage of this method is the large amount of information available in three-dimensional space, but the disadvantage is the high computational cost, requiring detailed information about the work area. The second approach is through stratigraphy, determining the stress direction in a plane. Current stratigraphic methods calculate this by differentiating and calculating the rate of change of stratigraphic undulations, which requires the use of seismic waveforms. Neither of these methods can directly provide a preliminary understanding of the tectonic stress in the work area.

[0010] Therefore, it is necessary to develop a method, device, electronic equipment, and medium for predicting the direction of tectonic stress.
