  • Calculations Of Drill Pipes Collapse Pressure - Drilling

    Nov 02, 2017 · The tabulated collapse pressure ratings must be divided by a safety factor in order to establish the allowable collapse pressure. S.F. = safety factor = 1.1 to 1.2. If the drill pipe is subjected to an axial tensile load, the collapse pressure ratings from the tables must be derated. The effective collapse corrected for tension load can be

  • Annulus - an overview | ScienceDirect Topics

    This load case (see Table 12.23) is applicable to offshore wells.One envisions the well shut-in, with the tubing above the closed subsurface safety value (SSSV) bled to a low pressure (or evacuation). The tubing develops a leak below the SSSV that can flow until the tubing and annulus pressure equalize at the location of the leak. Above the leak the pressure is determined by subtracting the

  • Tubing design factors - PetroWiki

    Jun 29, 2015 · For combination tubing-string design, the collapse and tensile loads should be evaluated at the bottom and top of any tubing size, weight, or grade change. In directional wells, the effect of the wellbore curvature and vertical deviation angle on the axial stress on the tubing body and couplings/joints must be considered in the tubing design.

    Oct 18, 2017 · Tubing Specifications. Tubing is a relatively small-diameter pipe that is run into a well to serve as a conduit for the passage of oil and gas to the field surface facilities for processing. Tubing must be adequately strong to resist loads and deformations associated with production and workovers. Further, tubing must be sized to support the
