The Integrated Application Of Prestack And Post-stack Seismic Attribute Fracture Prediction In Damintun Buried Hill

With continuous exploitation of oil and gas resources,the direction of oil and gas' s exploration and development is swing gradually from conventional reservoirs to special reservoirs.Fractured-vuggy reservoirs,as a kind of typical unconventional reservoirs,it's formation of the reservoir is diverse,and the anisotropy is obvious.Therefore,the exploration and development of fractured oil and gas reservoirs is more difficult.Qianjin buried hill has experienced many years of exploration and development work,and found that multiple sets of longitudinal cracks Development Zone.Aiming at the complexity of fracture type oil and gas reservoirs.Common crack prediction techniques include seismic fracture prediction and fracture prediction of well logging data.In this paper,we mainly use prestack seismic data and post stack seismic data for comprehensive fracture prediction.At first the log data are used to predict the fracture.Then using prestack seismic data to extract the amplitude and attenuation properties to predict the pre stack fracture.Then the seismic data were processed by the PCA-SVD filtering process,and the post stack seismic attributes such as curvature,coherence,ant body,wavelet frequency and so on were predicted.At last get the development and distribution of the fracture in QianJin buried hill...
