Abstract:

Gas permeability of rock is higher than liquid permeability with high dependence of pressure, which is considered to be caused by slippage effect or Klinkenberg effect. Slippage effect means that gas flows through pores without any friction with the wall of pores, which is a wrong view to permeability measurement. The high pressure dependence of gas permeability is the result of misuse of gas viscosity. Gas viscosity changes dramatically with pressure under low pressure condition, but a certain gas viscosity is chosen to determine the gas permeability in laboratory. Slippage effect makes the measurement of gas viscosity impossible. Irregular thermal motions of gas molecules lead to collide into walls of pores at random, which prevents the gas molecules slip from walls of pores. The gas permeability of rocks is higher than liquid permeability, which is the result of comparison of fluid molecule size with the pores of rock. There is no free molecular motion in discrete form underground at all. A pore with only a few methane molecules in it is not worth being exploited, and is not worth being studied. Slippage effect does not make any sense for production practice. It is suggested not to take the slippage correction for gas permeability measurement.
