横波时差也反映地层孔隙度的变化，因此利用横波时差来计算地层的孔隙度是可行的。
Shear moveout reflected the porosity variation, it was feasible to compute porosity by using shear moveout.
当泥饼层较厚时，用斯通利波幅度衰减估算的地层渗透率及提取的横波时差是错误的结果。
When mud cake is thick, formation permeability and shear wave slowness evaluated from the attenuation of the amplitude of Stoneley wave are wrong.
理论认为当储层中存在着天然气时，会导致纵波时差增大，横波时差不变，密度测井值减小，中子孔隙度减小。
Theoretically, when gas exists in reservoir, longitudinal wave offset time will increase and transverse wave offset time will not change and density will decrease and neutron will decrease, too.
