Abstract
In the oilfield development stage, more recoverable reserves can be found by using the more sophisticated seismic methods with stimulation. Three-component seismic exploration technology comes into being, and it is becoming a major oil exploration seismic technology currently. As the sensitive element of seismic geophone, the performance of the harmonic oscillator is vitally important to the entire seismic exploration. The working principle of the harmonic oscillator is introduced, the solid model of harmonic oscillator mass is created by using the finite element method, and its three-dimensional static analysis and modal analysis are carried out. Load is applied and solved. The first fourth-order model is taken for analysis. The frequency of twentieth order vibration mode of physical model is 78 kHz; the total displacement of twentieth order is 0.122×10 -6 μm; and the total displacement of the solid model is 0.236×10 -19 μm.
