Abstract
A system for relieving lateral stress on rods within a wellbore. A flexible sucker rod coupling has a top connecting member threadedly attached to a ball shank housing. The ball shank housing houses in a ball and socket fashion, a ball shank which extends out of the ball shank housing, defining a swivel gap to allow swivel movement. The ball shank is threadedly attached to a lower connection member. Both ends of the coupling threadedly attaches to an adjacent sucker rod within the wellbore. The ball shank is secured to the ball shank housing to ensure that the ball shank and the ball shank housing rotate together.
Claims15
A system for relieving lateral strain on a rod string within a wellbore comprising:
- at least one flexible sucker rod connection assembly for attaching to adjacent sucker rods within said wellbore, said sucker rod connection assembly comprising:
- a top connecting member adjacent and attached to a ball shank housing, said ball shank housing receiving a portion of a ball shank therein;
- and
- a bottom connecting member spaced from said ball shank housing, and connected to a lower portion of said ball shank;
- and
- an adjustable adjustment rod assembly attached to a polished rod of a pump jack above said wellbore, said adjustment rod system comprising:
- an adjustment rod comprising external threads along a lower portion, said adjustment rod engaging with said polished rod and said pump jack
- a load adjustment housing receiving said adjustment rod and being slidable along a longitudinal axis of said adjustment rod and attachable thereto at a desired location;
- and
- an adjustment rod connector comprising internal threads on a top surface thereof, said internal threads threadedly engaging said external threads of said adjustment rod, and a lower portion comprising external threads.
A system for adjusting the engagement of a polished rod with a pump jack comprising
- an adjustment rod comprising external threads along a lower portion,
- a load adjustment housing receiving said adjustment rod and being slidable along a longitudinal axis of said adjustment rod and attachable thereto at a desired location;
- and
- an adjustment rod connector comprising internal threads on a top surface thereof, said internal threads threadedly engaging said external threads of said adjustment rod, and a lower portion comprising external threads,
- a ball shank comprising a ball and a lower portion, said ball of said ball shank disposed within a ball shank housing which is attached and adjacent said adjustment rod connector, and said lower portion extending through the bottom of said ball shank housing, defining a swivel gap between said ball shank housing and said lower portion of said ball shank;
- said ball shank housing comprising internal threads along an internal top portion thereof for receiving said external threads of said adjustment rod, and
- wherein said ball shank comprises a collar along said lower portion, and internal threads along an internal bottom portion.
An apparatus for relieving lateral strain between two rods within a wellbore, said apparatus comprising:
- a top connecting member;
- a ball shank housing attached to said top connecting member along a bottom portion thereof, said ball shank housing receiving a portion of a ball shank therein;
- and
- a bottom connecting member spaced from said ball shank housing, and connected to a lower portion of said ball shank;
- wherein said ball shank housing comprises a plurality of slotted apertures extending there through, a corresponding plurality of screws inserted within said slotted apertures and engaging a corresponding plurality of internal threads within a ball of said ball shank, said screws being slidable within said slotted apertures to provide controlled swiveling movement within a swivel gap defined by a space between said lower portion of said ball shank and said ball shank housing.
