Abstract:
The study of seismoacoustic noise has revealed many scientific and practical applications of this phenomenon. The noise data can be used in prediction of rock-bursts in mines, of earthquakes and other dynamic processes in the earth's crust, and in monitoring of oil and gas wells. Such data were used in developing new well-logging techniques that differentiate between geologic sections and solve other similar problems. Most of these studies were carried out in mines at high man-made interfering noise levels, and where the rock bodies were strongly disturbed, or on the continents under surface conditions, or in oil and gas wells where the noise signal is commonly generated in the presence of high gas pressure. In this paper the authors discuss their results in measurements of seismoacoustic noise at the medium to great depths in deep boreholes.
