In order to realize high resolution seismic acquisition, we carried out comparison test with 3-component digital geophone, magnetic levitation geophone, and conventional geophone.

Then the conclusion have been concluded from the test that the character of three component geophone with component angle of 90 degree is etter than the character of three component geophone with component angle of 54 degree.

Currently, there are many problems in crossfeed testing of 54° three component geophone.

Seismic data damage due to polarity inversion of 54°three-component geophone;

Analysis of planting error of three-component geophone;

The author conducts a meaningful test through "the super microspread" of three-component geophones with the group interval being 20cm.

Application and effect of digital geophone;

Seismic data character of single-point digital geophone and processing strategy.;

However, based on full-digital seismic exploration technology, the digital geophone system is employed, as well as digital signals exported from digital geophones are digitally transmitted into key stations for arrangemen.

The performance of the digital detector used in cable receive channel has been improved obviously.
