Abstract: Longitudinal metal flowof solid expandable tubularwas studied according to stimulant mechanical environment of borehole in this paper. The 35CrMomaterial pipe was selected to be tested. Meshed experiment was adopted to study the plastic deformation of metal. The results of the test and analysiswere indicated the metal flowwas non-uniform on the longitudinal direction of tubular. The results of metallographic examination have proved that the results of meshed experiment is correct, it is concluded that meshed experiment can be used to research the oilfield tubular goods.

Key words: solid expandable tubular, metal flow, meshed ex-perimental method
