Resistivity Lateral Video Logging

Mine-use lateral resistivity video imaging logging instrument, multi-point remote detection instrument

The mine-used explosion-proof acoustic logging instrument is a device used for measuring the propagation characteristics of sound waves in underground rock layers, mainly applied in geological exploration and oil and gas exploration. It measures the speed, amplitude attenuation, etc. of sound waves to evaluate the geological profile of drilling, determine the quality of cementing, classify rock types, and determine the porosity of oil and gas reservoirs.
The acoustic logging instrument studies the physical properties of underground rock layers by emitting sound waves and receiving their reflected or transmitted signals. The propagation speed, amplitude and frequency of sound waves in different rocks vary, and these changes can be used to determine the nature of the underground rock layers. The acoustic logging instrument usually includes a sound wave generator and two receivers. By measuring the time difference of sound wave propagation between the two receivers, the propagation speed of sound waves in the rock layer can be calculated.
