Research On High Resolution Processing In XZ Area Of Songliao Basin

With the further exploration and development of oil fields,old data acquisition as a result of the acquisition of technical limitations,there are lower coverage,less the number of road features,has been unable to meet the requirements of increasingly fine reservoir prediction.This area is an old area of oil and gas exploration for many years.In addition to several two dimensional seismic exploration,the area also deployed the XZ 3D seismic area in 1993,and the surface element is 25 m x 50 m.From the exploration perspective,in addition to the central area of the slope,two tectonic faults,complex things,the lateral variation of sandstone,multilayer oil and gas space and has a certain capacity,1993 deployment of binning of 3D seismic cannot accurately determine the tectonic location and the fault location,space combination to accurately fault combination of plane and fault,especially small faults and low amplitude structure.The present processing and interpretation results have not been able to meet the geological needs of oil and gas development.The research and application of high resolution seismic data processing technology in XZ area is applied.The application includes the technology of tomography static correction,high fidelity amplitude preserving denoising,surface conformation deconvolution,surface uniformity surface absorption compensation,deterministic spectrum widening technology,prestack Hof time migration and other technologies,which can form a set of high resolution seismic processing technology suitable for this area,which can significantly improve the black emperor.The recognition ability of the temple,grape flower,especially the Fuyu oil layer satisfies the precise interpretation of the 5 points of the subdivision layer of the Fuyu oil layer,while ensuring the fidelity,the signal-to-noise ratio and the resolution of the results section,which can meet the needs of structural interpretation and lithologic interpretation.
