现场和实验室数据表明，在低频地震范围内，流体饱和的储层具有异常高的反射率。还观察到，反射信号是频率相关的，并且与储层流动特性密切相关。我们得到了流体饱和多孔介质地震反射波在低频域的渐近表示。反射系数的频率相关分量与信号的频率和储层中流体的流动性的乘积的平方根成比例。这为在钻井之前定位油田的最高产区域提供了机会。在所给出的例子中，我们量化低频成像振幅属性的储层流体流动性和储层生产率。理论我们考虑一个角频率的平面弹性压缩波从干的和流体饱和的弹性多孔介质之间的边界的反射。在岩石和流体性质的合理范围内，
Field and laboratory data indicate anomalously high reflectivity from fluid-saturated reservoirs at the low-frequency seismic range. It also has been observed that the reflected signal is frequency-dependent and is strongly related to the reservoir flow properties. We have obtained an asymptotic representation of the seismic reflection from a fluid-saturated porous medium in the low-frequency domain. The frequency-dependent component of the reflection coefficient is proportional to the square root of the product of frequency of the signal and the mobility of the fluid in the reservoir. This provides an opportunity for locating the most productive zones of the field before drilling. In the presented example we quantify lowfrequency imaging amplitude attribute in terms of reservoir fluid mobility and reservoir production rate. Theory We consider reflection of a plane elastic compression wave of an angular frequency from the boundary between dry and fluid-saturated elastic porous media. Within a reasonable range of rock and fluid properties, the dimensionless parameter ω
