摘要
Abstract
Acoustic curves are the basic data essential for the wave-impedance inversion based on the logging restraint. But the acoustic data obtained from practical work usually cannot well reflect the changing rules of subsurface lithology based on the logging curve reconstructive method. The paper presents 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 uses natural gamma, natural potential, compensated neutron and resistivity curves(after normalization correction) to participate in reconstruction while 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 D region, which showed that the method is simple, practical and effective curve reconstructive technique.关键词
