Helical Buckling of Pipes in Extended Reach and Horizontal Wells—Part 1: Preventing Helical Buckling

Journal of Energy Resources Technology, Transactions of the ASME, 1993
Abstract This paper studies the helical buckling of pipes (drillstring and tubing) in extended reach and horizontal wells, theoretically and experimentally, resulting in new equations to correctly predict and effectively prevent the helical buckling of pipes in such wells.

Helical buckling of a thin rod with connectors constrained in a cylinder

International Journal of Mechanical Sciences, 2014
Abstract Kinds of tubular columns with connectors are widely used in petroleum exploration and development field. In previous research, tubular columns are usually treated as homogeneous thin elastic rods constrained in a cylinder and little attention has been paid to the effect of connectors.

Mechanism of the Transition From In-Plane Buckling to Helical Buckling for a Stiff Nanowire on an Elastomeric Substrate

Journal of Applied Mechanics, Transactions ASME, 2016
In this work, the compressive buckling of a nanowire partially bonded to an elastomeric substrate is studied via finite-element method (FEM) simulations and experiments. The buckling profile of the nanowire can be divided into three regimes, i.e., the in-plane buckling, the disordered buckling in the out-of-plane direction, and the helical buckling ...

Helical buckling of a thin rod with connectors constrained in a torus

International Journal of Mechanical Sciences, 2015
Abstract Kinds of tubular strings are widely applied to oil exploration & development. In the preceding studies, theses tubular strings are usually taken as homogeneous thin rods without connectors constrained in a straight cylinder or torus. Recent studies have indicated that the effect of connectors on the tubular strings is ignorable. On the basis

Helical Buckling of Pipe with Connectors and Torque

Proceedings of IADC/SPE Drilling Conference, 2004
Abstract It has been generally recognized that connectors should have some effect on the buckling of pipe. For instance, the connector outside diameter may be as much as 50% greater than the pipe body diameter. As a result, the radial clearance of the connector can be substantially smaller than the radial clearance of the pipe body.

Buckling transition in long α-helices

The Journal of Chemical Physics, 2014
The treatment of bending and buckling of stiff biopolymer filaments by the popular worm-like chain model does not provide adequate understanding of these processes at the microscopic level. Thus, we have used the atomistic molecular-dynamic simulations and the Amber03 force field to examine the compression buckling of α-helix (AH) filaments at room ...
