ABSTRACT
The tubing string will be deformed or even broken when subjected to axial compression load. In the study, the stability of tubing string was discussed when the joint was taken into consideration. First, the tubing and the joint was dispersed into various elements and their element matrices were derived separately. Secondly, the whole transfer matrix of the tubing string was derived based on transfer matrix method by sequential matrix multiplication of tubing element matrix and joint element. Then, the critical buckling load was derived by taking into consideration the boundary condition. At last, the influence of the outer diameter and the length of joint on the critical buckling load in vertical well were discussed with partial tubing and joints in API Spec 5CT as the objects. The derived critical buckling load of tubing string considering the joint will be more accurate than that derived by the ordinary method in which the tubing string was simply taken as a thin-wall cylinder of uniform cross-section.
