US Patent:

41007824, Jul 18, 1978

Filed:

Nov 1, 1976

Appl. No.:

5/737540

Inventors:

Robert A. Clay - Tustin CA

International Classification:

B24C 100

US Classification:

72 53

Abstract:

A shot peening process is provided for treating elongated oil well sucker rods, drill pipes and the like. In accordance with the process of the invention, the rods or pipes are passed through appropriate shot peening equipment along an arcuate path, and each rod or pipe is simultaneously rotated about its longitudinal axis. This action causes the rods or pipes to be flexed during the shot peening action. The effect of the flexing is to set the inner fibers of the rods or pipes under compression, thereby extending the fatigue resistance of the treated rods.

Abstract:

A pumping unit for removing oil or the like from a well. The unit comprises a tower, a sump at the bottom of the tower and a reservoir at an elevation above the sump. A liquid, such as oil or water, is pumped from the sump up to the reservoir. A wheel is mounted at the top of the tower above the reservoir for rotation, and a line extends over the wheel for attachment at one end to a polished rod load outside the tower and at its other end to a receptacle inside the tower serving as a counter weight for the polished rod load. The receptacle is reciprocally movable up and down in the tower between the reservoir and the sump, liquid being transferred from the reservoir to the receptacle as it approaches the reservoir in an amount sufficient to reverse the upward movement of the receptacle, causing it to descend in the tower, and liquid being transferred from the receptacle to the sump as the receptacle approaches the sump in an amount sufficient to reverse the downward movement of the receptacle, causing it to ascend in the tower.
