Pump Drive Unit for Water, Oil or Other Fluid Extraction

摘要

A reciprocating seesaw-type (upward-downward) pump drive unit for water, oil, or other fluid extraction; the pump drive unit uses a pumping rod string that allows pumping fluids from depths of thousands of meters. This unit can be used in any well operated with mechanical pumping, without making any changes to the existing installation, achieving a reduction of around 20% in pumping and operating equipment costs. The drive unit includes a piston (2) that slides up and down inside a vertical hydraulic cylinder (4) with the application of an actuating fluid, and where the piston shaft (2) is the rod string's polished rod (1).

1. Pump drive unit for water, oil or other fluid extraction able of providing a reciprocating motion (upward/downward) to a pumping unit through a pumping rod string (a); the drive unit includes a piston (2) that slides up and down inside a vertical hydraulic cylinder (4) as a result of the application of an actuating fluid, characterized in that the piston shaft (2) is the sucker rod string's polished rod (1).
