Annotation:

The author of the article proposes a model describing the influence of random factors such as an initial curvature, asymmetry and heterogeneity of the pipes and tooling design on the distribution of forces and moments in the transport column and liner when they move in the well. Special attention is paid to the effects that occur during buckling (bend of pipes under the action of longitudinal compressive forces) – an increase of contact forces and a change of pipes longitudinal deformation. By modeling of experiments on compression of stainless tubes inside acrylic pipes, the efficiency of the proposed model is demonstrated – both from the point of view of calculating longitudinal deformations of tubes and from the point of view of calculating longitudinal forces. The proposed model allows simulating the jamming of compressed pipes in wells as well as using a probabilistic methodology for justifying well designs.

This model was implemented in the Well Force ZERS 3.0 program, a demo version of which is available at: http://programs.werymag.ru/Programs (the program description and presentation are available after installing the program).
