我们用理论模型对经常在储层周围出现的三种地质结构的长波长的传播特性和衰减特性进行了研究。理论模型由一组簿的粘弹性平面展组成,其中的平面层或是固体或是流体。在不同材料的界面是胶结的假设下,巴克斯理论对薄层和一组流体充填的微裂隙作丁适当的描述。我们利用体积品质因子和剪切品质因子的相对值模拟了饱和度对波衰减的影 We used theoretical models to study the long wavelength propagation and attenuation characteristics of three geological formations that often occur around reservoirs. The theoretical model consists of a set of viscoelastic planar expanses in which the planar layers are either solid or fluid. Under the assumption that the interfaces of the different materials are cemented, the Barks theory properly describes the microfractures of thin layers and a set of fluid fills. We use the relative values ​​of volumetric quality factor and shear quality factor to simulate the influence of saturation on wave attenuation
