Abstract：The tests of geophones with different free frequency are conducted in order to improve resolution. It is considered by tests that the geophones have different free frequency. showing as different suppression for low-and high-frequency interference in single shot records,but there are no distinct differences in frequency and energy between several geophones after data processing. The high-resolution exploration is not equal to high frequency exploration,but is wide band exploration instead, so that selection of geophone with low free frequency is suitable for high-resolution exploration.
