FIELD: mining.
SUBSTANCE: there is created mathematical model of pressure pulse distribution inside the borehole and fracture. It is fed into well pressure pulse train by means of ground-based equipment and it is registered well response to pressure pulse by means of pressure sensor. It is defined bottom-hole pressure, corresponding feeding of each pulse. It is introduced mean fracture width by means of mathematical model of pressure pulses distribution inside the borehole and fracture and ratio between simulated mean fracture width and derived bottom-hole pressure. It is extrapolated particular ratio into point of zero width and it is defined healing pressure as bottom-hole pressure, corresponding to zero width.
EFFECT: effectiveness increase of method ensured by ability of definition of pressure for fracture healing before fracture is closed - on the basis of estimation of mean fracture width.
