Basic Principles and System Composition
Basic Working Principle
The EV80 emits seismic waves underground through continuous and controlled vibration:
The control system generates a sweep frequency signal (from low frequency to high frequency). The electro-hydraulic servo system drives the vibrator to oscillate up and down at high speed. The vibration baseplate is tightly pressed against the ground, transmitting vibration energy underground. Seismic waves reflect back to the surface when encountering subsurface formation interfaces. Geophones receive the signals to form a subsurface geological image. Summary:Computer controls hydraulics → vibrator transmits energy into the ground → generates seismic waves → reflects and images to locate oil and gas.Overall System Composition
Heavy-duty off-road chassis: 8×8 or 6×6 heavy-duty chassis with high-power engine, providing excellent off-road passability. Vibration system (core working components): vibrator assembly, vibration baseplate, loading hydraulic cylinder, guiding mechanism. Hydraulic system:high-pressure oil pump, servo valve, hydraulic oil tank, cooling and filtering system. Electronic control & operating system: main control computer, synchronous control unit, GPS positioning, operation panel. Auxiliary system: heat dissipation, lubrication, sand-proof sealing, emergency safety devices.
Basic Principles and System Composition
Positioning and Driving: Navigate to the designed shot point via GPS and park accurately.Lowering the Baseplate: Lower the vibration baseplate and apply pressure to ensure tight contact with the ground.System Self-Test and Parameter Setting: Check hydraulic, electronic control and synchronization status; set sweep frequency range and sweep duration.Vibration Sweep: Start vibration and perform continuous sweep at the set frequency to emit seismic waves underground.Synchronous Acquisition: Synchronize time with geophones and seismic recording stations to record reflected signals.Quality Control: Review recorded data; proceed if signals are qualified, or reactivate if unqualified.Retracting and Relocation: Retract the vibration baseplate, drive to the next survey point and repeat operations.Post Data Processing: Perform data stacking, processing and imaging to finally generate subsurface structure maps for oil and gas exploration.
