| Abstract: | Due to the strong heterogeneity,anisotropy,low porosity and permeability of matrix in the Cretaceous carbonate reservoirs of Tarim Oilfield,it was difficult for reservoir prediction in Lungu Area of Tarim Basin.The reservoir prediction methods using frequency-spectral decomposition were used to further improve the accuracy of reservoir prediction.Different decomposition methods had different advantages,faults,and applicable conditions.The method of frequency-spectral decomposition technique of S-transformat... |
