| 摘 要： | 分频解释技术将地震数据体从时间域转化到频率域,可实现在频率域内通过调谐振幅的对应关系来研究储层横向变化规律。黄河口地区明化镇组地形平缓,储层薄,横向变化快,依据常规地震属性以及波阻抗反演技术很难准确地进行储层预测。运用连续小波变换实现频率域对储层横向变化的研究,确定了油藏的边界,计算出了砂体的厚度,为储层预测提供了依据。

| Abstract: | Spectral decomposition is a unique technology,which can transform the seismic data from the time domain to the frequency domain,to study the changes of lateral reservoirs through the corresponding relationship of amplitude tuning in the frequency domain.Minghuazhen formation in Huanghekou area has characteristics of gentle terrain,thin reservoir,and fast lateral variation of the reservoir.Therefore,it is difficult to predict reservoir by conventional seismic attributes and wave impedance inversion techniques.By using continuous wavelet transform in frequency domain,the lateral variation of the reservoir was studied to determine the borders of the reservoir,and calculate the thickness of the sand body.This provided a base for reservoir prediction. |
