Logging Wave Acoustic Multi-Frequency Cement Meter KVARTS-60

Logging wave acoustic multi-frequency cementometer KVARTS-60 is designed to identify vertical channels in wells between the string and cement stone, with an openness of at least 40 degrees, in oil and gas wells. The equipment provides registration of acoustic wave fields excited by a monopole transmitter operating in multi-frequency mode depending on the goals and objectives of the study. Registration of acoustic signal is carried out by groups of receivers, in 4 sectors, located in 90 degrees around the perimeter of the device. The field of application of the device is research by the method of wave acoustic logging of cased wells with inner diameter from 73 to 127 mm at the upper values of ambient temperature 105 C and hydrostatic pressure 60 MPa with the angle of inclination of the well not more than 40, at logging speed up to 280 m/h.
