Seismic Inversion Prediction Technology of Es_3 Formation Reservoir in Qibei Slope

There are complex relations between the oil and water of Es3 formation reservoir because of the sand body interactive overlays and lateral changes in Qibei slope.The existing seismic data has problems of the vertical and horizontal low resolution.Thus it can not meet the need of high precision reservoir prediction.Based on the synthetic study of geology,through the analysis and processing of seismic data,the standardization of well logging curves and reconstruction of characteristic curve,wavelet extraction and horizon calibration and some other early processing,and optimizing parameters,inversion study of GR simulation acoustic logging is carried about to define the exhibition and thickness of favorable sand body and to provide strong support for wells deploymented and reservoir evaluated in Qibei slope.
