FIELD: mining.
SUBSTANCE: complex downhole instrument comprising device for temperature exposure of formation and two identical probes for acoustic logging is installed in well. While probes of acoustic logging are arranged symmetrically along instrument height relative to device of temperature exposure of formation. In process of instrument movement along well, formation is exposed to temperature, and simultaneously continuous acoustic logging of well is carried out, and formation temperature is measured, as well as speed and attenuation of Stoneley waves generated by logging probe. Using produced dependencies of speed and attenuation of Stoneley waves from temperature, relative permeability ratios are determined for a formation.
EFFECT: improved information value of methods for geophysical research of wells, expansion of technological and functional capabilities of equipment for geophysical research of wells.
