Geological factors and engineering factors is a major factor to damage, the drivepipe deformation under pressure seismic load which used to establish mathematical model of the mechanical model can calculated the stress and strain analysis of the casing. The drivepipe damage to this article on the mechanism research on the mechanical model of drivepipe analysis under Seismic load, based on the drivepipe through the focus on the impact and stress damage to the mechanical method of drivepipe deformation studies, and the models of a drivepipe failure mechanism of the mechanical and mathematical are established, which will scientifically, accurately predict the damaged drivepipe.
