Abstract

Summary

The parameters of acoustic emission of fluid saturated-sample of terrigenous reservoir type with external acoustic impact using the device of the core research for the conditions close to the reservoir are studied. It is registered and made a detailed analysis of the acoustic emission signals in the porous space of the core in dry and liquid saturated conditions of different types: water, kerosene, oil. Core, saturated by oil, have a maximum value of the accumulated signal and a correspondingly high velocity signal output, which has a pulse character. For the cores, saturated with water, can be seen a steady decline of the signal, and the acoustic emission signal dispersion for water saturating was at least 2–3 less than by oil saturating. It is detected the connection between the acoustic emission changes and saturation of the reservoir, which occur after the external acoustic impact on it, which is reflected in an increase of acoustic emission level in the oil-saturated reservoir and decrease in water-saturated reservoir.
