Abstract: One of main damage fetos in low peme bili sndsase gas pol is stes sivi. degre of which is dependen on rock's fature. The compotion, conlen, dstibuion of gains, cement, pore stucture and throat feture are all iner factors that afet and demine the size of stress sitviy. Duing the rseach of stes sesitvity damage of low pemebiltly sandsone gas pol, natural cores aroe used for the eperimental anlysi, and empirial equation beween abolute pemebliliy and alete pesure is given. Baed on this equation, the poduetvity and pessure dstibuion equatios of low pemabiltly sandstone gas pool are derived wih cnsidera tion of sres sitviy. Furthermore, the efcts of stres sesitvity on the podutivity of sandstore ges pol are dscussed.
