摘要: 傅立叶频谱分解技术在塔中地区被广泛用于碳酸盐岩储集层平面和空间描述,在塔中碳酸盐岩油气勘探中发挥了重要作用。利用离散傅立叶变换得到的调谐振幅体、相位体数据及离散振幅体数据,对塔中45井区奥陶系良里塔格组的缝洞型储集层、断裂裂缝系统的刻画以及储集层含油气性检测等3个方面的应用,取得了良好的效果。

Abstract: Fourier spectrum decomposition technique is widely applied in plane and spacial description of carbonate reservoir in Tazhong area. The tuning amplitude, phase and discrete amplitude data from Fourier spectrum transform (FST) are applied to the fractured-vuggy reservoir description, fault or fracture system carving and reservoir hydrocarbon-bearing detection of Lianglitag formation of the Ordovician in TZ-45 Wellblock in Tazhong area, and good effects have been obtained.

Key words: Fourier spectrum transform, tuning cube, discrete cube, fault, hydrocarbon detection, TZ-45 Wellblock
