Bulk viscosity 意味
WebThe bulk modulus of any pore fluid must be used to interpret the seismic response and perform a fluid substitution for direct hydrocarbon indicator analysis. However, fluids will have losses and show dispersion as a result of the viscoelastic behavior of the bulk modulus. This be-havior can be described through the bulk viscosity. Bulk ...
