Multi-channel cross-hole acoustic logging testing is an advanced geological exploration technique widely used in energy exploration such as oil and gas, as well as in the assessment of groundwater resources. This technique provides a clear picture of the subsurface geologic structure by transmitting acoustic waves in multiple boreholes simultaneously and capturing the information of the waveforms at the receiving point.
The basic principle of multi-channel cross-hole acoustic logging utilizes the properties of sound waves propagating in different media. When sound waves encounter different geologic layers, they are reflected and refracted due to changes in the density and elasticity of the medium. By recording the propagation time and waveform characteristics of the sound waves, experts are able to analyze the physical properties of the formation, such as density, porosity and water saturation. This process provides important data support for geologists and engineers, enabling them to make more scientific and rational decisions.
Multi-channel cross-hole acoustic logging test is also important in environmental monitoring and underground structure assessment. With the advancement of urbanization, underground engineering is becoming more and more complex, and there is an urgent need to accurately assess and monitor underground structures. Through sonic logging technology, engineers are able to obtain the movement status of the underground soil layer in time, prevent potential geologic disasters, and provide data support for sustainable development.
