Abstract
In the present chapter the distribution of stresses, strains, and displacements around a deep vertical shaft or oil well will be studied, assuming that the depth of the well is much larger than its diameter. For the mathematical formulation of the problem, the well is considered to be a circular cylindrical vertical orifice drilled in a semi-infinite space. Cylindrical coordinates r, θ, z will be used, with the 0z-axis coinciding with the axis of the well and directed vertically downward. The initial raidus of the well is r = a.KeywordsConstitutive EquationEquivalent StressRadial DisplacementStress VariationPrimary StressThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
