Application of Frequency Attenuation Gradient in Reservoir Prediction in Block Kartake 1 of Tazhong Area

The carbonate in Block Kartake 1 of Tarim Basin had better prospects of exploration for oil and gas,but vuggy reservoirs in this area were smaller,deeper with strong and vertical heterogeneity,which increased the difficulty for reservoir prediction.Through analysis of attributes sensitivity of drilled wells,it indicates that the frequency attenuation gradient reflects well to the reservoir fluid and it is applied to the reservoir prediction,which obtains good effect,the technology can be used as an effective technique in Tazhong Area.
