    摘要： A marine vibrator may include a containment housing, a sound radiating surface, and a compliance chamber. The compliance chamber may include a compliance chamber housing, a non-linear linkage assembly, and a low pressure chamber. The compliance chamber housing may define at least a portion of a compliance chamber internal volume having a compliance chamber internal gas pressure. The low pressure chamber may comprise a low pressure piston and a low pressure chamber housing. The low pressure chamber housing may define at least a portion of a low pressure chamber internal volume having a low pressure chamber internal gas pressure. The low pressure piston may be configured to move in response to a pressure differential across the low pressure piston such that a resonance frequency of the marine vibrator may be changed.

    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： Systems, sensors, and methods for high-speed image monitoring of baseplate movement in a vibrator. The systems can include a baseplate defined by an area, disposable at a ground surface to direct a seismic force into the ground surface. The system can include a reaction mass coupled to and positioned above the baseplate to generate the seismic force at the baseplate. The system can include an actuator assembly coupled to the reaction mass to vibrate the reaction mass, as well as high-speed image units directed at the area of the baseplate. The high-speed image units can include photo detectors to sense a distribution of acceleration across the area of the baseplate, and a light source emit light to be sensed by the photo detectors. The system can also include a controller coupled to the actuator assembly, that drives the actuator assembly.
