WIDE BANDWIDTH BOREHOLE DIPOLE SOURCE |
摘要 |
<p>A dipole source for borehole acoustic logging is provided, including a cylindrical shell, a center beam coupled to the cylindrical shell and a movable projector inside the cylindrical shell to impact the center beam. The dipole source includes a cavity acoustically insulating the interior of the cylindrical shell from the exterior of the cylindrical shell. An acoustic logging tool for making measurements of a substrate surrounding a borehole with a body insertable in the borehole is also provided. The body includes an acoustic detector and a dipole source as above, along the axial length. The acoustic logging tool may include a control unit to process data collected from the acoustic detector and obtain information about the substrate surrounding the borehole. According to embodiments disclosed herein, a method for operating a dipole source and an acoustic logging tool as above is provided.</p> |
