The Results Analysis Of High-resolution Data Analysis And Processing Of Pre-stack Seismic Data And Its Application To Seismic Interpretation

With the improvement of exploration technology,the requests from interpretation people for high resolution of seismic data have become increasingly demanding.Due to the impact of the earth filter attenuation and absorption of the medium,high frequency seismic wave is mainly absorbed by the Earth resulting in high-frequency seismic waves with the loss of energy and phase distortion.Improving the image quality of high frequency part of the seismic data becomes necessary.As we all know,the more wide-band seismic data,the higher the frequency and the higher the resolution of seismic data.When the premise of seismic data acquisition technology is not greatly improved,high-resolution seismic data processing is important and effective way to compensate the most attenuation of seismic energy.Only when there is a high resolution seismic records,we can clearly identify its smaller geological bodies,interpret and predict the hydrocarbon reservoirs to meet the needs.There are many ways and means to improve the resolution of seismic data,but the evidence and base to evaluate the high resolution processing results should come from the requests and purpose of interpretation by combining the processing and interpretation.In this paper,we start from various testing processing for improve the resolution both in pre-stack and post-stack domain including deconvolution,Q compensation,spectral whitening,spectral adjustment,and in accordance with requests for the gas reservoir prediction,the reasonableness of a variety of high-resolution processing methods have been chosen and the best parameters have been decided.Finally,we propose a suitable high-resolution seismic processing approaches and its practical workflow.On the other hand,with the new high-resolution data processing results,we also carried out a detailed interpretation and gas reservoir prediction to provide a new interpretation results with the new processing data for the study area,which is suitable the actual geological conditions in the area.
