摘要： Methods and systems for acoustically determining reservoir parameters of subterranean formations. A tool comprising at least one seismic source or seismic receiver mounted thereon; a conveyance configured for movement of the acoustic tool in a borehole traversing the subterranean formations; and a source retainer configured or designed for permanent deployment in the borehole to removably retain the acoustic tool in the borehole. The source retainer when deployed provides acoustic coupling with the borehole and removably retains the acoustic tool in the borehole so that, over multiple deployments, the acoustic tool is repeatedly deployed at the same predetermined location and orientation relative to the subterranean formation, and with the same acoustic coupling to the borehole.

摘要： A seismic source of the present disclosure includes a first rotation member and a second rotation member having a common axis of rotation and rotated at a same rotational rate in mutually opposite directions. In addition, the seismic source may include a first mass that is eccentrically coupled to the first rotation member and rotates along with the first rotation member. A second mass may be eccentrically coupled to the second rotation member and configured to rotate along with that member. The second mass may be configured such that the center of gravity of the second mass is located radially external to the center of gravity of the first mass relative to the common axis of rotation. The center of gravities of the first and second mass may be located at the same location along a length of the common axis of rotation.

摘要： Methods and systems for determining coil eccentricity of seismic sensors configured or designed for use in seismic signal detection. A direct electrical current is applied to a moving coil of a seismic sensor such that the moving coil is dislocated from a neutral position relative to the magnetic field in the seismic sensor. A predetermined indicator is measured and eccentricity of the coil (δ) relative to the center of the magnetic filed is determined using the predetermined indicator.

摘要： To attenuate a surface seismic wave, seismic sensors having a predetermined orientation with respect to a surface are provided, where the seismic sensors receive seismic waves including a seismic wave reflected from a subterranean structure and the surface seismic wave propagating in at least a first direction that is generally parallel to the surface. A signal that represents a partial derivative of a wavefield containing the surface seismic wave is provided, and the signal is integrated to obtain a response in which the surface seismic wave is attenuated.
