The density of Nitrogen foam fluid is small and controllable, and the viscosity is much higher than the water, so that it is widely used in washing sand, cleaning well, flowing well by displacement and so on. Ø        Nitrogen foam fluid is especially good for applying in low pressure, low permeability oil layer; Ø        Damage the oil layer very little, especially in under negative pressure condition Ø        The cleaning effect is much better than the ordinarily way; Ø        Nitrogen foam fluid can be the revulsive of the oil when applying in the downhole.
