Application of prestack seismic inversion to predict natural gas in Sanhu area,Qaidam basin;

By analyzing the conventional seismic inversion methods and overcoming their defects,a prestack seismic inversion method based on support vector machine was proposed ensuring the inversion effect.

One-way wave equation seismic prestack forward modeling with irregular surfaces;

A research on the factors to influence post-stack seismic inversion during oilfield production

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.

People are increasingly turning to the information extracted from prestack seismic gathers as seismic data of wide azimuth and long offset are now easily available.

On the basis of analyzing the feature of fractural development in the core and evaluation of prestack seismic data,the paper used prestack seismic azimuth anisotropic technique to detect regionally the fractural developing density and direction of Lower Triassic Jia-2 reservoir in TNB structural belt,analyzed the distributing rule of relative development zone of fracture.
