3) the ratio of shear slowness to compressional slowness
横纵波时差比值
1.
The analysis of acoustic propagation properties in rocks shows that the shear slowness and the compressional slowness in tight zones increase with the increasing porosity of fractured reservoir,and the ratio of shear slowness to compressional slowness is unchanged within certain range of the porosities in fractured reservoir.
通过对声波在岩石中传播特性的分析发现,致密性储层的横波和纵波时差都随着储层孔隙度的增大而增大,在一定孔隙度区间内横纵波时差比值基本不变;但当致密性储层中发育裂缝时,其横波时差有明显增大,而纵波时差变化不明显。
