Abstract

Waves of different geometries (plane, cylindrical and spherical) in a porous medium saturated by a three-phase fluid: water, oil and gas is considered. Unified dispersion relations for waves with different geometries are obtained. It is shown that the dependence of phase velocities on frequency is the same for plane, cylindrical and spherical waves (with axial symmetry) and independent of the geometry of the process.

三相流体饱和的多孔介质中不同几何形状的波

摘要

考虑了被三相流体饱和的多孔介质中不同几何形状（平面、圆柱和球形）的波：水、油和气。获得了具有不同几何形状的波的统一色散关系。结果表明，平面波、柱面波和球面波（具有轴对称性）的相位速度对频率的依赖性是相同的，并且与过程的几何形状无关。
