A novel earthquake physical model material is synthesized by special preparing equipment and processes and used for building an earthquake physical model according to a similarity principle to simulate a real geological structure; and the earthquake physical model can be used for research on seismic wave field and researches for other purposes, particularly used for researching kinematics and kinematic characteristics of seismic waves propagating in complicated areas; moreover the earthquake physical model can provide objective bases for verification of new methods and new theories in oil-gas exploration and development.

Description

technical field [0001] The invention relates to the field of geophysical exploration, in particular to a seismic physical model for simulating actual geological structures in seismic wave field research, a preparation method and application thereof. Background technique [0002] With the continuous deepening of oil and gas exploration and development in my country, the focus of expanding oil and gas discovery has gradually extended to complex areas. Many geological phenomena and wave field propagation theories are in urgent need of further verification and improvement, and exploration methods also need to be further developed. [0003] Seismic exploration is one of the important methods in geophysical exploration. It is based on the elasticity of rock. The basic method of research is to artificially stimulate seismic waves with explosives or non-explosives. When seismic waves pass through different underground media, due to their elastic properties and The geometry is diffe...
