| In the oilfield development stage, more recoverable reserves can be found by usingthe more sophisticated seismic methods with stimulation. Three-component seismicexploration technology comes into being, and it is becoming a major oil explorationseismic technology currently. As the sensitive element of seismic geophone, theperformance of the harmonic oscillator is vitally important to the entire seismicexploration.This issue which comes from the national natural science foundation of Chinacombines Micro-Opto-Electro-Mechanical System with three-component explorationtechnology. Firstly, the existing harmonic oscillators of three-component accelerationseismic geophone are analyzed and compared, and its structure is optimized. Theharmonic oscillator of Micro-Opto-Electro-Mechanical System three-componentacceleration seismic geophone is designed. Then the static characteristics, dynamiccharacteristics and the natural frequency of three-component acceleration seismicgeophone are analyzed. Next, the solid model of harmonic oscillator mass is created byusing the finite element method, and its three-dimensional static analysis and modalanalysis are carried out. Finally, the micro-processing technology and productionprocesses of the harmonic oscillator of three-component acceleration seismic geophoneare discussed. The research and analysis results of harmonic oscillator mass by finiteelement method provide a theoretical basis for the damping design of three-componentacceleration seismic geophone and its further development. |
