Abstract：In order to raise lithological recognition capacity and inversion resolution for the characteristic curves,well logging-seismic multi-attribute stratified reconstruction characteristic curve technique was applied in well constraint inversion.It is pointed out in this paper that the change of density data is sensitive for inversion results.The multi well logging and seismic attributes were integratedly utilized to invert lithological characteristics,for different target zones,the reconstruction processing was conducted for sonic curves and density curves respectively.The application results showed that the sonic curves and density curves on which the well logging-seismic multi-attribute stratified reconstruction and inversion were conducted could remove some impacts,such as high sonic velocity,density distortion and so on which were caused by factors like high resistance mudstone,wellbore collapse and etc.,as a result the difference between reservoir and surrounding rocks was highlighted and lithological recognizance capacity and inversion resolution were raised.
