Abstract

During exploiting the tight sandstone gas reservoirs,the descent of pore pressure will induce the virtual stress increase,which makes the permeability drop,and it is basic reason of the gas reservoirs production descent.The study of stress sensitivity damage mechanism can provide a reasonable foundation for protection the tight gas reservoir.Taking Daniudi gas field tight sandstone as example,the factors of rock compositions,fracture,temperature,water saturation and repeatedly pressuring were considered for it.

Key words： Daniudi gas filed; Tight sandstones; Gas reservoirs; Stress sensitivity; Gas reservoir protection.
