Abstract

The invention belongs to the field of earthquake physical models, and particularly relates to a geophysical reservoir model. The model is mainly made of epoxy resin, silica gel, aluminum powder and other compositions, the longitudinal and transverse wave speed of a model material is controlled by changing the contents of the components, the longitudinal wave speed can be controlled to be graduallychanged between 2800m / s and 4900m / s, and the transverse wave speed can be controlled to be gradually changed between 1500m / s and 2600m / s. The reservoir model manufactured by adopting a geophysical reservoir model composition and a manufacturing method has good penetrability under strong pulse excitation of laser ultrasound, good seismic wave reflection data can be obtained when the model is applied to physical simulation test, and a new method is provided for reservoir geologic body and laser ultrasound research.

Description

technical field

[0001] The invention relates to the field of geophysical exploration, in particular to a reservoir model composition and a preparation method for seismic acquisition of geophysical exploration simulation. Background technique

[0002] Earthquake physical simulation is to use ultrasonic waves to simulate field seismic waves in the laboratory, and to excite and receive signals through ultrasonic transducers. It is an effective means to study the laws of seismic wave propagation. Physical models that conform to actual geological structures or different reservoir types are made in the laboratory. To study the kinematics and dynamics characteristics of seismic waves in complex structures and complex reservoirs, the materials for making physical models must have certain geological characteristics. Now major institutions and universities mainly use epoxy resin and silicone rubber to synthesize seismic physical models Material, by changing the ratio of epoxy resin an...
