摘要

Summary "source of the dipole to record acoustic of boring hole, the registration tool, acoustic method to generate an acoustic wave in a pattern space having an axis of symmetry of the dipole and method for measuring properties of a substrate, a source of the dipole for the record acu00fasti Co of boring hole is provided, including a coating cylinder.A central beam coupled to the cylindrical coating and a projector mobile inside the cylindrical coating to impact the central beam. The source of the dipole includes a cavity acoustically isolating the interior of a cylindrical coating outside the coating cylinder.A tool to record acoustic to make measurements of a substrate surrounding a drill hole with a body insertable in a boring hole is also provided. The body includes an acoustic detector and a source of the dipole as above, along the axial length.The tool of the acoustic record may include a control unit for processing data collected from the detector noise and to obtain information on the substrate surrounding the drill hole. According to the configurations disclosed here, a method for operating a source of dipole and a registration tool acoustic as above is provided. 1 / 1
