Convolution model-based NMO and implementation approach;

Three-parameter velocity analysis of converted wave and NMO method.;

Aimed at horizontal reflection plane in HTI medium with arbitrary anisotropic degree and according to converted wave NMO velocity formula at discretional azimuth angle (the angle between line orientation and direction of main axis),in this paper we inverse anisotropic parameters using genetic algorithm.

A method for removing NMO correction lengthening;

The paper studied the impact of velocity analysis and NMO correction based on hyperbolic equation on stack velocity and to time and presented improvement method.

In this method, a partial NMO correction is first applied for common shot record (or common middle-point record), and then the chose proper curvature parameter “q”, and the Parabolic Radon transform is applied for the data contaiming zero traces at the missing offset locations.

An auto-correction method on retention time shifting was used to improve the effect of further analysis of complex chromatographic data, and related software was also developed to practical application.

The feasibility of double light path compensation method and reference solution spectral auto-correction method against system drift during building model and measuring process were respectively researched and experimentally verified.

Velocity analysis and normal moveout correction based on linear continuous velocity model;

The paper analyses the cause of anomalous stretch of normal moveout in seismic data processing and the characteristics digital normal moveout correction.

Through introducing the moveout correction technique in exploration seismology,we obtained a method to compute the receiver function beneath a station by stacking receiver function after normal moveout correction.
