Abstract：The paper theoretically analyzed that modelbased wave impedance inversion mainly has following problems:first，the experience-based build-up of wave impedance model leads mufti-solution;second,the non-uniformity of goodness of fitting synthetic seismogram into seismic records near borehole resulted in modeling phenomenon. Because of this reason,the paper presented a set of methods for mufti-logging parameters inversion under the constrain of relative wave impedance data volume，among which the relative wave impedance data volume is obtained by the trace-integrated algorithm.The paper also interpreted the physical meaning of trace-integrated algorithm in frequency domain --making the seismic data shift-900 of phase in effective frequency band. The paper analyzed，by real cases，the mufti-logging parameters inversion methods under the constrain of relative wave impedance data volume，that proved the practice and feasibility of the methods presented.
