Down-hole tubular string buckling is the most classic and complex part of tubular string
mechanics in well engineering. Studies of down-hole tubular string buckling not only have …

The heavy elastica models thin or slender elements with non-negligible density. The non-
linear governing equation depends on a non-dimensional parameter representing the …

In high-angle wells the force of gravity pulls the drill string against the low side of the hole.
This stabilizes the string and allows drill pipe to carry high axial loads without buckling. In …

关于井下管柱力学的研究迄今已有七十多年的历程, 取得了许多重要的研究成果,
并主要在油气井工程中获应用实效. 然而, 由于井眼约束和作业工况的复杂性 …

Almost unique in engineering analysis is the problem of tubing buckling in wellbores. In
general, structures loaded above their critical load fail catastrophically. Yet, both tubing and …

Drillstring dynamics and hole cleaning problems are some of the most important limiting
factors in extended reach applications. Here, long sections of the drillstring lie on the low …

A comprehensive buckling model, a group of fourth-order nonlinear ordinary differential
equations, was derived by applying the principle of virtual work. Lateral friction force is …

Tubular strings in oil and gas wells are the backbone and central nervous system of oil and
gas drilling and production operations. Tubular mechanics in oil and gas wells is the most …

Horizontal well is one of the main measures to improve oil and gas production capacity.
However, with the extension of horizontal section, the risk of pipe string buckling will be …
