  • Improved Rod String Taper Design | SPE Annual

    1990-9-23 · This results in stretch and suggests that an ideal construction would be a continuous taper from top to bottom. Since such a shape is impractical, the use of tapered strings with sections of decreasing diameters is a common design practice. practice. The most basic property of any sucker rod string is its elastic behavior. P. 605

  • An Enhanced Model for the Design of Tapered

    2016-2-1 · Because most sucker-rod breaks are fatigue failures, the mechanical design of a sucker-rod string must consider the cyclic nature of rod loading and the appropriate fatigue-endurance limit of the rod material. This is why most string designs use the modified Goodman diagram for calculating the lengths of rod tapers. Available sucker-rod-string design models calculate rod …

    1995-10-16 · A tapered rod string design for a directional well is more complex than for a vertical well. Based on the theory of a continuous beam column, the rod string design in a directional well is a trial and error method. The key to reduce the time to obtain a solution is to rapidly determine the minimum rod diameter.

    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.

  • Rod String - an overview | ScienceDirect Topics

    Thus a rod string made up of 1 in, 15/16 in, and 7/8 in continuous rods is designated as 64: since the largest rod in the string is 16/16 in, the first numeral of the code is a 6, and the second numeral is 4 because the smallest rod size is 14/16 in. Composite fiberglass–steel rod strings are usually designated by a four-digit code.
