FIELD: measuring equipment.
SUBSTANCE: invention relates to geophysics and can be used for determining density of a geological formation. According to certain versions of implementation, described is a device and system, as well as method and product, which can be used for determining compressional velocity (CV) in the geological formation, reflection coefficient (RC), related to the geological formation, and density of the geological formation based on compressional velocity (CV) and reflection coefficient (RC). Compressional velocity (CV) and reflection coefficient (RC) can be determined from values, associated with the results of measurements of the sound and ultrasonic wave propagation speed.
EFFECT: high accuracy of obtained data.
