摘要

 According to the demand of accurate reservoir description for intense adjustment and potential tapping in ultra-high water cut stage of Daqing Oilfield and directed by fine reservoir characterization and high-density 3D seismic data of Daqing placanticline under the condition of dense well pattern,the methods of the high fidelity seismic processing by the integration of seismic date processing and interpretation,the method of high-density fine synthetic calibration and the method of strata slice optimization have been established.Aiming at distribution of different types of sand bodies,the identification method of single channel with the feature of "looking for shale in sand" and "looking for sand in shale" has been given by using strata slices.The accurate reservoir description method using logging and seismic data and "directed by seismic attribution and controlled by single well facies" has been formed.The results show that the methods are much more appropriate for analyzing remaining oil.Horizontal well scheme design in D area has been guided by the results of identifying point bar,and the effects of drilling sand bodies are good.
