Abstract

The utility model relates to a recessed accumulator of vibroseis vibrator used in vibroseis system of oil seismic exploration equipment, which is composed of a vibration pituitary 1, a press cover 4, an energy accumulation gas-filling nozzle 5, and an energy accumulation rubber bag 6. The energy accumulation rubber bag 6 is provided between the vibration pituitary 1 and the press cover 4, the end of the energy accumulation rubber bag 6 is provided with the energy accumulation gas-filling nozzle 5 so as to improve vibroseis exciting performance and reduce output signal deformation, and also enhance signal-noise ratio of vibroseis during exciting process.

Description

The built-in accumulator of vibroseis Vib.
The utility model is a kind of built-in accumulator of vibroseis Vib. that is used for oil seismic exploration equipment vibroseis vibrational system.
Conventional design of Hydraulic System, at height, low pressure end all is provided with corresponding accumulator and comes the interior fluctuation of absorption liquid pressure pipeline, but because locational cause is set, the pressure surge phenomenon still exists, the source of excitation signal causes interference strength and excitation intensity is proportional, therefore this influence is exciting the performance on rank (tonnage) vibroseis particularly outstanding greatly, vibroseis work has adopted hydraulic pressure to wait upon dress system, because the variation of scanning output signal direction, the change procedure that has brought load to replace, cause having produced in the hydraulic system pressure surge phenomenon, maximum pulsating quantity surpasses the several times of setting value, this wave phenomenon will influence the output quality of seismic signal, also can damage some low pressure load bearing equipments simultaneously.
The purpose of this utility model is to provide a kind of epicenter excitation performance of improving, and reduces the distortion of output signal, improves the built-in accumulator of vibroseis Vib. of vibroseis signal to noise ratio (S/N ratio) in excitation process.
The utility model is achieved in that by vibration hypophysis 1, gland screw 2, O-ring seal 3, gland 4, accumulator charging connector 5, accumulator leather bag 6 to be formed, vibration hypophysis 1 is connected by gland screw 2 with gland 4, between vibration hypophysis 1 and the gland 4 accumulator leather bag 6 is arranged, there is accumulator charging connector 5 end of accumulator leather bag 6.
Vibration hypophysis 1 has O-ring seal 3 with gland 4 junctions.
Advantage of the present utility model is: improved the epicenter excitation performance, reduced the distortion of output signal, improved vibroseis signal to noise ratio (S/N ratio) in excitation process.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described:
Form by vibration hypophysis 1, gland screw 2, O-ring seal 3, gland 4, accumulator charging connector 5, accumulator leather bag 6, vibration hypophysis 1 is connected by gland screw 2 with gland 4, between vibration hypophysis 1 and the gland 4 accumulator leather bag 6 is arranged, there is accumulator charging connector 5 end of accumulator leather bag 6, and vibration hypophysis 1 has O-ring seal 3 with gland 4 junctions.
Porch at the Vib. hydraulic circuit, be provided with built-in (or online) accumulator from manifold piece inside and come the absorption pressure fluctuation, improve the quality of output signal, consider hydraulic pressure wait upon dress system over the ground the singularity of the shock excitation influence of signaling and high and low pressure pulsating quantity get big or smallly, only the low pressure end at the inner oil duct of Vib. is provided with the gasbag-type accumulator.
