Abstract：In view of the issue that sonic logging curve is easily affected by various factors and does not reflect the character of reservoir, and on the basis of deeply studying the logging curve reconstructive method, the paper presented a multi-curve sonic reconstructive technique that can truly reflect the character of reservoir. The method can both keep the time-depth relation of sonic curve and all frequency information to be unchanged, and also fully use the characteristic information of reconstructive curve participated since the method used natural gamma, natural potential, compensated neutron and resistivity curves (after normalization correction) to participate reconstruction on the basis of keeping the property of sonic curve. The method achieved good results after carrying out wave impedance inversion and prediction of reservoir in the case of S region, which showed that the method is simple, practical and effective curve reconstructive technique.
