This paper discusses several key problems need to be solved in high resolution processing based on analyzing the main effecting factors in high resolution processing and puts forward a set of practical high resolution processing technique.The focal point is to expound processing methods including reasonably remove noise before stack,amplitude recovery,combination deconvolution and multiple residual correction to improve the resolution of the seismic data. In practical seismic data processing achievement profile,wave group characteristics of every reflection zone are clear,information of layer to layer is rich and wave shape is natural and stable.Compared with old profile,resolution,signal to noise ratio,wave characteristics achieved in seismic profile of high resolution processing technique is improved obviously,which could better fulfill the requirement of the seismic data interpretation. This shows that this set of high resolution processing technique has a value of popularizing and application.
