Abstract：Liuxi basin is sma11,however,the seismic velocity varies drasticly in both horizontal and vertical directions because the physical and chemical characteristics of rocks vary severely and the formations are tomplicatedly fractured,Fortunately, both the horizontal and vertical variations in velocity are regular in this basin,thus the velocity curve,of each seismic horizon 'can be obtained using known logging velocity curves or velocity curves from velocity spectra.The corresponding horizon velocity curves are used to make time一depth conversion of TS and TS seismic horizons.The error analysis of 36 wells in this basin shows that relative errors between 5%respectively except prospect.the converted depth and actual depth are less than few)，fulfiling the accuracy requirement in this.If the time一depth this area,the relative conversion is made using the general velocity in errors of TS horizon are above 1000.
