FIELD: physics.
SUBSTANCE: disclosed is a method of determining geometric characteristics of hydraulic fracture cracks, which involves use of natural lithological reflectors lying under artificial hydraulic fracture cracks. The method involves optimisation of the arrangement of seismic sources and receivers in accordance with the location of reflectors and the investigation zone. Through differential measurement of the tintage of the transverse wave and splitting of the transverse wave, which is achieved by subtracting the seismic signal before fracture and during fracture, the obtained seismic signal of the artificial hydraulic fracture crack can be efficiently converted to useful information on the size and shape of the crack.
EFFECT: high accuracy of determining geometric characteristics of cracks.
