FIELD: oil and gas industry.SUBSTANCE: when at least one acoustic probe is being moved in the well, continuous acoustic well logging is performed at simultaneous temperature action on the formation. Formation temperature, as well as speed and attenuation of Stoneley waves are measured. Stoneley waves are generated with well logging probe. Based on the received relationships of measured parameters and temperature of formation, relative phase permeability of formation, viscosity of formation fluid and activation energy of viscous flow are determined.EFFECT: higher determination accuracy.6 cl, 1 dwg, 1 ex |
