The orthogonal seismic trace set up on the concept of complex seismic trace is combined with the real seismic trace to form the imaginary part and the real part of the complex seismic trace.

According to the research of energy characteristic and data fractal dimension of time window on the seismic trace,automatic recognition technologies for polarity reverse and others six abnormal traces were presented,and the evaluation of distribution attribute of overall acquisition quality region was proposed.

The correlation of biolimestone thickness and seismic reflecting amplitude and frequency were clarified by establishing seismic forward model for different enclosing rock combinations and different biolimestone thickness.

The study taking the data volume acquired from model and seismic forward simulation as object can push development and bringing forth new ideas of seismic approaches.

It's very successful that complex seismic trace technique is applied in seismic data processing of petroleum geophysical prospecting,but in the domain of engineering geophysical prospecting the application is less,or the effect is not good.

Complex seismic trace technique has been used to obtain instantaneous parameters,which are of great importance to seismic data interpretation,reservoir description and lithologic information obtainment.

Based on complex seismic trace method,instantaneous polarization filter has been constructed.
