Abstract

The distribution of sand bodies detected by the well pattern can not meet the needs of the remaining oil tapping potential in the middle and late stages of the old oilfields,because the fluvial reservoirs frequently cause the thinning of the thickness of the single sand bodies and the quick lateral change.According to the characteristics of fluvial fancies reservoir in the Gangdong oilfield,Dagang,a three-dimensional model was established for the reservoir prediction method experiment,and the method of spatial distribution of single-stage channel sand body was explored.The results show that the contribution of seismic reflection to the seismic record energy of each set of sand bodies is analyzed by means of discrete synthetic seismic records.It is found that the amplitude slices extracted from the zero reflection energy of one set of seismic reflection energies of sand bodies can reflect the other set of single sand bodies' spatial distribution,and the single sand body can be predicted by this method.The zero-value method can effectively depict the lateral variation characteristics of the cross-well sand body and provide a strong basis for determining the oil-water relationship and adjusting the well pattern deployment in the Gangdong oilfield.

Key words： fluvial facies thin interbedding zero value method three-dimensional model reservoir prediction
