Abstract：As the response difference of sonic logging curve in Daqing placanticline oilfield for reservoir and non-reservoir is not obvious, the gamma-ray curve is chosen to replace the sonic logging curve in reservoir prediction, that is, the time-depth relationship from the near wells are used to reconstruct gamma-ray curve, so the reconstructed gamma-ray curve will have dimension of the sonic logging curve. Based on the new constructed curves, by integrating the high frequency information from the logs with the 3d seismic data which can be 3d visualized in detail, well constrained inversion is conducted, and then the authors carried out the reservoir prediction. The inversion results demonstrated that the accuracy rate to predict intra-well sand bodies reached up to 70%, as a result the prediction results can be used in the following reservoir integrated modeling, so the modeling accuracy rate can be raised.
