摘　　要：叠前同步反演方法具有横波和纵波两种地震信息,可有效识别岩性与含油气性、综合预测石油储层的发育规模和位置。利用该方法实现DH油田的储层精细识别,通过地震角度部分叠加、测井曲线处理及子波提取的关键环节质控,提高反演结果精度,解决储层纵波阻抗体叠置的难题。利用该方法预测出DH油田砂体沉积整体西薄东厚,储层砂体主要集中在东部BH-3和BH-6井之间,具有较大的挖潜空间,展现了该方法在该区良好的应用前景。The prestack synchronous inversion method has two kinds of seismic information,including S-wave and P-wave,which can effectively identify lithology and oil-bearing property,and comprehensively predict the development scale and location of oil reservoir.This method was used to realize the fine reservoir identification in DH oilfield.Through the key links of seismic angle partial superposition,well logging curve processing and wavelet extraction quality control,the accuracy of inversion results can improved and the problem of stack of reservoir P-wave resistance antibody can be solved.Using this method,the sand body of DH oilfield was predicted to be thin in the West and thick in the East.The reservoir sand body is mainly concentrated between well BH-3 and well Bh-6 in the East,which has a large potential to tap,showing a good application prospect of this method in this area.
