Abstract
Summary
As one of several time-frequency analysis methods for VSP data, W-V distribution has widely been used and provides better time-frequency concentration and reliable distribution edges, but s seriously impacted by the cross-term interference. An adaptive W-V distribution method is proposed to suppress the cross-term interference of VSP data based on spectrum decomposition W-V distribution. We apply the method to the field VSP data of Tarim Basin and the adaptive W-V distribution result are significantly related to oil-gas characteristics.
