Abstract ：The formula construction of the unified model with the squirt and the Biot mechanism, i.e. the BISQ model [Geophysics 58 (1993) 524], is discussed. The inconsistent formula construction caused by the self-contradictions of key assumptions is pointed out and demonstrated. Once the deformation of the solid skeleton is assumed to be in the uniaxial mode, the deformation of pore fluid is not able to be non-uniaxial at all, but must be uniaxial. Therefore, the expected results in the BISQ model's paper are doubtful and this model needs to be improved. A combination of the two mechanisms simultaneously in theory is significant and still needs more research.
