At present it is difficult to identify the lithologic traps in medium-shallow layers of north Songliao Basin,so,for fine geologic research,the eigenvalue related body technique is applied to fine structural interpretation and reservoir forecasting.

The basic task of fine structure interpretation is the mutual verification of 3D seismic data interpretation and drilling result so as to guide wellsite adjustment and improve success rate of finding effective reservoir.

Application of fine interpretations of velocity spectrum in Guan 11 block in Dongying sag;

Application of fine interpretation technique of 3-D high-precision seismic data to development of Tu-Ha hill oilfield.;

Sondex production logging tools have compact construction, high sample accuracy and posses their own unique advantages on the defination of 3-phase profile and the fine interpretation of production profile.
