ANALYSIS ON THE DOWNHOLE STRESS OF SLIP SUPPORTED PACKER
Applying the static force equilvalent method,this paper calculates the hoop stress and axial buck ling force of casing due to the setting of slip supported packer,analyses the effect of pressure difference between the both sides of casing on the casing strength,finds out the cause of casing damage in hot-water closed-cycle wells,and offers the measures and suggestions for the prevention of casing dam.
