Abstract：The Chunguang prospect area located in the west of the Junggar Basin is characterized by thin-thickness,small-scale,and rapid-lateral-variation reservoirs.However,conventional high-resolution inversion methods are not completely applicable for the reservoir prediction in the area.Therefore,we propose in this paper a segmented-frequency-band fusion inversion to predict these special reservoirs.Conventional model inversion results are used as initial model,and high frequency seismic data is processed with high-resolution inversion algorithms.With log-constraint model inversion,this method can improve both the vertical resolution and the lateral accuracy.And the high resolution seismic inversion with tuning-frequency constraints can reduce the uncertainty of horizontal interpolation of high-frequency logging data.The application proves the effectiveness of the proposed method.
