  • Sucker Rod String - an overview | ScienceDirect Topics

    The tapered rod strings are designated by 1/8-in. (in diameter) increments. Tapered rod strings can be identified by their numbers, such as: 1. No. 88 is a non-tapered 8 8 - or 1-in. diameter rod string. 2. No. 76 is a tapered string with ⅞-in. diameter rod at the top, then a 6 8 -in. diameter rod at the bottom. 3.

  • Improved Rod String Taper Design | SPE Annual

    1990-9-23 · The sucker rod string is a vital part of the pumping system, since it provides the link between the surface pumping unit and the subsurface pump. Proper design of the rod string has a great impact on the system efficiency. Rod failures always involve servicing costs and lost production.

  • Rod String - an overview | ScienceDirect Topics

    Figure 4.2 shows a rod string section with a uniform cross-sectional area, A, and length, L.The coordinate axes x and u are directed downward and represent axial distance and displacement of the rod along the string, respectively. In order to find the governing equation for the movement of the string, a force balance must be written for an incremental element of the rod.

  • An Enhanced Model for the Design of Tapered Sucker

    2016-2-1 · A properly designed sucker-rod string should provide failure-free pumping operations for an extended period. Improper design of rod tapers can lead to early mechanical failures (rod breaks) with a complete termination of pumping action and an inevitable loss of production.

  • The Design of Sucker-Rod Strings | Engineering360

    2021-7-12 · The weight of the sucker-rod string is distributed along its length, and any section has to carry at least the weight of the rods below it. This fact suggests that the ideal sucker-rod string would be a continuous taper from top to bottom. Since such a shape is practically impossible to achieve, one tries to approach the ideal construction by ...
