In order to analyse the pressure sensitivity feature of high-dip fractures in the extra low-permeability sandstone reservoirs,  the contrast experiment among matrix sample,  bearing natural fracture sample and bearing artifieial fracture sample of extra low-permeability reservoirs in Ordos basin was accomplished.  The experiment results indicate quite obvious pressure sensitivity feature of fractures in the extra low-permeability reservoirs.  The matrix sample without fracture has medium pressure sensitivity and the samples with fractures have strong pressure sensitivity.  The bigger the fracture aperture and permeability,  the stronger the pressure sensitivity is.  The stronger the pressure sensitivity,  the lower the resumptive degree of fracture permeability is.  The pressure sensitivity of fractures is of great significance to the development of the extra low-permeability sandstone reservoirs.
