Abstract: The existing high energy gas frauring technology can efficiently break up arenaceous rock above 1000 meters,and raise the yields of the oil and gas. Bat it can not efficiently bresk up the carbonate rock under 1500 meters. the main reason lies in the unknown besting ability of the well casing,and the worry that wells woul collapse as the pressure rises. In this paper,FEM is used to d fine the limit pressure under 1500 meters,under which the well casing would not break.
Key words: well casing, limit pressure, FEM, bearing ability
