Abstract

The multi-polar resonance detailing device in this invention consists of a detailing head, a device for generating 2-n-polar sound waves in the original crustacean that surrounds the borehole but is separated from the well by. The destroyed zone when n is an integer greater than zero. And a device for detecting the signal of a sound wave 2 raised to the reverse polarity is refracted in its primary shape. The waveforming device consists of four identical piso eletric hollow cylindrical parts, both Four are polarized radially It is then connected to the detailing head in such a way that it forms a slit cylinder that shares the core with the axis of the detailing head. The electric pulse is supplied through the inner and outer cylindrical surfaces of the part. Individual parts These electric pulses have polarity in a way that causes adjacent parts to oscillate radially in the opposite phase. The vibrations of each part will cause The waves are compressed in fluid in the borehole, which intervenes to form four-pole sound waves in the surrounding crustal rock. This sound wave may be deflected in the original crust and will be detected by a signal detector. The signal detector device consists of two signal detectors in a borehole, far from each other and from a device to generate longitudinal waves. If a sound wave 2 raised to the n polarity is a compression wave, then the compression wave speed in the original crustal shale is determined by the time between detection of a 2 to the n polarity of the reverse polarity that is refracted by a signal detector. Both if a sound wave 2 raised to the n polar power is a shear wave. Shear wave velocity in primitive tectonic strata may be similarly obtained, the radius of the destroyed zone may be achieved from the compression wave velocity in the primitive crustal strata and in the destroyed zone. Or from the shear wave velocity in the primitive tectonic layer And in the destroyed zone
