All digital seismic pre-stack reservoir prediction technique and its application for gas exploration in the Sulige area

During the processing,tomography inversion was used for near surface correction and de-noising by array and pre-stack migration to improve imaging quality.

Study on AVO pre-stack inversion technology;

In recent years,seismic pre-stack inversion becomes the hot point of seismic attribute and inversion study.

Application of prestack inversion in Sulige area;

The prediction accuracy for the effective reservoir can be improved by using prestack inversion to calculate elastic impedance and elastic parameters.

The common-used prestack inversion often carries out approximate linear processing for non-linear objective function, which makes inverted results approach to the global optimum solution; otherwise, it is easy to fall into local minimum.
