    摘要： Seismic shear-wave survey systems and methods that employ inclined borehole pairs with directional detonations. If the boreholes have substantially equal inclinations in opposite azimuthal directions, the resulting signal traces can be combined to isolate shear wave energy contributions, thereby offering potentially enhanced resolution and reduced-complexity interpretation. The boreholes may be cased to ensure repeatability for, e.g., monitoring of reservoir fracturing, treatments, and/or drainage. The directional charges may be immersed to improve coupling of seismic energy into the formation.

    摘要： A method for selecting parameters of a seismic source array comprising a plurality of source elements each having a notional source spectrum is described, the method comprising calculating a ghost response function of the array; calculating directivity effects of the array; and adjusting the parameters of the array such that the directivity effects of the array are compensated by the ghost response to minimize angular variation of a far field response in a predetermined frequency range. A method for determining a phase center of a seismic source array is also related, the method comprising calculating a far field spectrum of the array at predetermined spherical angles, and minimizing the phase difference between the farfield spectra within a predetermined frequency range by adjusting a vertical reference position from which the spherical angles are defined.

    摘要： The invention relates to a vibration generator for seismic applications comprised of a housing, in which are accommodated coils activated with AC current or electric pulses, and which is coupled to the object to be investigated via coupling elements. The invention addresses the problem of providing a readily portable and easily wieldable vibration generator, with which vibrations for geophysical explorations of near-surface subsoil structures can be carried out up to a depth of approximately 150 meters. The invention comprises that in the outer housing of the vibration generator an inner housing is accommodated, that the outer housing supports two coil cores on opposing sides, on each of which one coil is displaceably supported, and that the two coils are connected through the inner common housing, with both coils being activated with electric energy alternating in time. If one coil is activated continuously alternating initially with the positive wave component of an AC current control signal and the other coil with the negative wave component, a force-controlled vibration motion of the reaction mass results as a function of the applied AC current frequency. The same effect is obtained with the alternate application of a DC voltage to the two coils. Via the law of action and reaction, this motion is transmitted to the coupling element and in this way permits the introduction of the vibration motion into the object to be investigated. In contrast to the moving coil system conventionally used for electromechanical vibration transduction, the system according to the invention is based on the functional operation of a soft-iron instrument. To generate a motion in the opposite direction, two of these function elements are combined opposingly connected.
