Abstract:
A seismic source signal generator includes a mass, a primary accumulator and a . secondary accumulator, the secondary accumulator having an internal volume smaller than an internal volume of the primary accumulator. A method for generating a signal using a seismic vibrator includes operating the seismic vibrator using hydraulic fluid, damping hydraulic pressure deviations in the hydraulic fluid using a first accumulator in hydraulic communication with the hydraulic fluid, and damping pressure deviations in the hydraulic fluid using a second accumulator in hydraulic communication with the hydraulic fluid, the second accumulator having an internal volume smaller than an internal volume of the first accumulator.
Abstract:
A removable bore liner (30) is provided that substantially increases the dependability, flexibility and field serviceability of seismic vibrators (14) and other hydraulically actuated devices. A method for installing the removable bore liner (30) in a seismic vibrator (14) is also provided.
