摘要： Earth vibrators, such as servo-hydraulic vibrators, are improved to produce more output force and less distortion at very low frequencies by capturing mass from the vehicles which carry them, adding sufficient inertial mass to the reaction mass without adding much vehicle and equipment weight while also avoiding increases to the servo-hydraulic vibrator's stroke length. In particular, improvements to servo-hydraulic vibrators, at low frequencies, will couple some mass from the carrier vehicle frame and its load using non-rigid coupling only when additional mass is needed using dampers connected between the reaction mass and the carrier vehicle's frame, with the added damping being applied by a control system at very low frequencies of output where the vibrator is otherwise unable to produce force equal to its hold-weight.

摘要： A seismic shaker for exercising an excitation force on the ground has a base plate and a reaction mass connected to the base plate via a resilient structure and an actuator parallel thereto. A first comparison unit sends a difference signal which is the difference between a displacement measured by a displacement sensor and a set value of the displacement. A control unit calculates a correction value as a function of this difference signal, and sends it to a second comparison unit, which adds the correction value to a value of the excitation force to be exerted set in the second comparison unit. This second comparison unit is connected to a controller unit which controls the actuator. At Low frequency this position control will track the ground force through the position set-point. The position feedback loop will be able to suppress the interfering force of the spring and any hysteresis.

摘要： Method, source array and source element that generate seismic waves. The source element includes an enclosure having an opening covered by a piston; a local supply accumulator fluidly communicating with an interior of the enclosure, a pressure of the fluid inside the local supply accumulator being larger than a pressure of the fluid inside the enclosure; a local supply valve located between the local supply accumulator and the enclosure and configured to control a flow of the fluid from the local supply accumulator to the interior of the enclosure; and a controller configured to control the local supply valve such that the pressure inside the enclosure does not fall below a first preset value based upon an ambient pressure of the enclosure while seismic waves are generated.

摘要： The invention is an electric sweep type seismic vibrator source of the type used in seismic prospecting for hydrocarbons. The source uses an engine and generator combination to create electric power for all systems on the source such as driving a frame of linear electric motors that direct a rod or piston to contact the ground in a recurring fashion along with driving the source from location to location through a survey area. The seismic source includes systems for driving the acoustic energy systems using electric energy concurrently from both the generator and an electric energy accumulator such as a capacitor or battery, systems for adjusting the weight on the acoustic energy delivery system by raising and lowering wheels individually and an active energy isolation to isolate the chocks and impulses of the acoustic energy delivery system from the remainder of the seismic source.

摘要： The invention is an electric sweep type seismic vibrator source of the type used in seismic prospecting for hydrocarbons. The source uses an engine and generator combination to create electric power for all systems on the source such as driving a frame of linear electric motors that direct a rod or piston to contact the ground in a recurring fashion along with driving the source from location to location through a survey area. Preferably a foot is arranged on the bottom end of the rod or piston for contact with the ground and by engaging the grid of motors to push down against the ground in a rapid progression, acoustic energy is created and delivered into the ground for geophones to sense and record. However, the rapid progression of pulses or sweep of seismic energy is delivered in a distinctive fashion as compared to a conventional upsweep or downsweep and the distinctiveness is also achieved by creating a designed cadence or timing such that each pulse in a series of pulses is not delivered in a regular timing. Several similar seismic sources may be employed where each is provided with its own distinctive series of pulses such that each may be identified within the data record and source separation from a number of seismic sources may be accomplished.

The transducer includes first electrodes and second electrodes opposing the first electrodes with gaps interposed between therebetween. The resistance per unit area of the first electrodes differs in a movable region relative to the second electrodes and an unmovable region relative to the second electrodes. The first electrodes in the movable region and the first electrodes in the unmovable region have different thicknesses.

摘要： Aspects described herein relate to an electromagnetic seismic vibrator (EMSV) architecture that provide wide frequency range operation, ground force application with high fidelity, and low environmental impact. The EMSV architecture can include a base member that can support a force coil and mitigate electrical heating due, at least in part, to spurious currents. The EMSV architecture can include means for restricting movement of a reaction member included in the EMSV architecture relative to the base member. Such means can permit mitigation of damage of the EMSV architecture in scenarios in which control of the EMSV architecture may fail.
