Abstract

The present invention intends to solve sleeve seizure in ball and plunger lift systems by the use of one or more spherical channel(s) indented into the separating rod. The indented spherical channel(s) act as an air bearing between the separator rod and the sleeve. In addition, the channels direct gas currents in a spherical fashion causing the sleeve to rotate. With this rotation of the sleeve, residues are agitated, as well as sheared off by the edges of the channels. Another benefit of this design is that each time the sleeve is actuated up or down the separator rod, during regular cycles, residues shear off in those actions as well. With the residues continually cleaned off the sleeve during regular cycles, the oil well's production can continue with depleted formation pressures and may not require injected pressure.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A ball and sleeve separator rod comprising:
 a structure of a cylindrical bar; a set of one or more spherical and recessed channels.   
     
     
         2 . A ball and sleeve separator rod comprising:
 a structure of a diameter fluctuating cylindrical bar; a set of one or more spherical and recessed channels.   
     
     
         3 . A ball and sleeve plunger separator rod according to  claim 1 , wherein said rod further comprising:
 spherical channel(s) in addition to or without one or more channels parallel to rod length.   
     
     
         4 . A ball and sleeve plunger separator rod according to  claim 1  further comprising:
 a structure tip that narrows by means of a linear bevel. 
 
     
     
         5 . A ball and sleeve plunger separator rod according to  claim 1  further comprising:
 a structure tip that narrows by means of a convex bevel. 
 
     
     
         6 . A ball and sleeve plunger separator rod according to  claim 1  further comprising:
 a structure tip that narrows by means of a concave bevel. 
 
     
     
         7 . A ball and sleeve plunger separator rod according to  claim 1  further comprising:
 a set of one or more spherical channels indented into said rod with an alignment of constant angle. 
 
     
     
         8 . A ball and sleeve plunger separator rod according to  claim 1  further comprising:
 a set of one or more spherical channels indented into said rod with an alignment of fluctuating angle. 
 
     
     
         9 . A ball and sleeve plunger separator rod according to  claim 2 , wherein said rod further comprising:
 spherical channel(s) in addition to or without one or more channels parallel to rod length.   
     
     
         10 . A ball and sleeve plunger separator rod according to  claim 2  further comprising:
 a structure tip that narrows by means of a linear bevel. 
 
     
     
         11 . A ball and sleeve plunger separator rod according to  claim 2  further comprising:
 a structure tip that narrows by means of a convex bevel. 
 
     
     
         12 . A ball and sleeve plunger separator rod according so  claim 2  further comprising:
 a structure tip that narrows by means of a concave bevel. 
 
     
     
         13 . A ball and sleeve plunger separator rod according to  claim 2  further comprising:
 a set of one or more spherical channels indented into said rod with an alignment of constant angle. 
 
     
     
         14 . A ball and sleeve plunger separator rod according to claims further comprising:
 a set of one or more spherical channels indented into said rod with an alignment of fluctuating angle.
