“…Numerical results are obtained for the X65 steel pipeline. The yield stress is 448.5 MPa [7], the young's modulus of the steel is 206 GPa, Poisson's ratio is 0.3, and the density is 7800 kg/m 3 . Mechanical behaviours of the stratum and rock material are represented by an elastic-perfectly plastic Mohr-Coulomb constitutive model [8].…”

“…Refinement of models of interaction between the surface of a rod and the elastic or non-elastic environment is required for the safe operation of long objects. The use of such models is relevant for pipelines in the areas of soil displacement [23], in places where a damaged base is mobile [24], and where active fault is crossed [25,26]. Similar models of contacting bodies are applicable to improve the durability of drill strings [27,28] and to provide quality centering of casing pipes [29].…”

exposed to the action of friction and contact forces, the forces of inertia from a washing fluid, etc. The listed phenomena exert a negative impact on the elements of a drill string, bits, downhole motors, and in general lead to a loss of energy and reduce the techno-economic indicators of drilling [1-4]. To refine the parameters of loading and the stressed-deformed state of a drill string, it is necessary to have a well-defined procedure for determining the moments of inertia of its curved sections. Therefore, it is a relevant task for the theory of dynamic stability of elastic systems to investigate the inertial properties of a curvilinear string of pipes at rotation. The solution to this problem is necessary in order to properly conduct a dynamic analysis of drill strings at rotor and rotor-turbine drilling techniques.

“…The fault plane divides the stratum into two blocks of equal size. The analysis is conducted in two steps as follows: first, gravity loading is applied to the whole model and internal pressure acts on the inner wall of the pipeline [8]. Subsequently, reverse fault displacement is imposed.…”

SummaryResponse analysis of the buried pipeline subjected to reverse fault displacement is very important for design, detection and protection of buried pipelines. This paper looks at the buckling behavior of a buried pipeline subjected to reverse fault displacement in the rock stratum. Effects of internal pressure, wall thickness, fault displacement and burial depth on the buckling mode and the axial strain of the buried pipeline are discussed. The results show that there are two buckling locations on the buried pipeline subjected to reverse fault displacement in the rock stratum and that the buckling modes of the buried pipes with different internal pressures are different. The two buckling locations are not symmetrically distributed along the fault plane. The buckling mode ranges from collapse to wrinkle as the internal pressure increases. The buckling phenomenon becomes more serious as the fault displacement increases, and the shape of the deformation curve changes from the S-shape to the Z-shape. The process of pipeline deformation can be divided into three stages. There is no buckling in the first stage. The second stage is a transition stage, buckling appears on the buried pipeline. Buckling is more serious in the third stage. Fault displacement has a small effect on the maximum strain position of the buried pipeline. The deformation curve of the buried pipeline is smoother as the wall thickness increases. The maximum axial strain of pressure pipes first increases and then decreases as the wall thickness increases.
