| Popis: |
An array of multi-component receivers used to acquire borehole-seismic data allows for measuring the compressional and shear components of a wave field from within the rock volume itself. Having determined the polarizations and the arrival times of the different components over the aperture of the array, we estimate their direction of propagation. The propagation direction essentially points back to the point of reflection, scattering or conversion. We describe how a ray-based migration/deconvolution process could be used to separate the scattered compressional component from other wave-field components by projecting the full 3C wave field on to or perpendicular to the ray connecting the receiver and image point. These components were used to give images from a 2D spread of source locations. |
