摘要： A method for operating a tandem motor linear rod pumping apparatus that includes first and second linear mechanical actuator systems each having a motor, and also includes a rod for a sucker-rod pump. The method calls for constructing the first and second linear mechanical actuator systems to operate within a single housing, and simultaneously operating each of the two motors in a manner that imparts reciprocating vertical motion to respective-vertically movable members of the first and second linear mechanical actuator systems. Each motor has a reversibly rotatable element that is operatively connected to the vertically-movable member of its respective linear mechanical actuator system, thus establishing a fixed relationship between the rotational position of the rotatable element and the vertical position of its respective vertically-movable member. The simultaneous operation of the two motors imparts a reciprocating vertical motion to the pump rod of the sucker-rod pump.

摘要： An apparatus and method for pumping fluids, such as water and/or hydrocarbons, from a subterranean formation or reservoir, include a linear rod pump having a mechanical rack and pinion drive arrangement, adapted for attachment to a pumping mechanism, such as the polished rod at the top of a rod string in a hydrocarbon well. The rack gear, of the rack and pinion drive arrangement, is adapted for connection to, and movement with, the polished rod. The pinion gear does not translate with the rack gear, and is driven by a reversible motor for affecting up and down reciprocating motion of the rack gear and pumping mechanism. Some forms of the invention include a compressible gas counter-balance arrangement. Some forms of the invention include an electronic drive configured for dealing with electric power generated by the motor during a portion of the pumping cycle.

摘要： A dual completion linear rod pumping apparatus for imparting reciprocating vertical motion to a pair of rods for respective sucker-rod pumps. The dual completion linear rod pumping apparatus includes first and second linear mechanical actuator systems disposed in a single housing. These linear mechanical actuator systems impart and control vertical motion of the pair of rods. Each linear mechanical actuator system includes a rack and pinion gearing arrangement. The rack is operatively connected in a gear-mesh relationship with the pinion. The pinion is operatively connected to a rotating output of a motor. Rotation of the motor in a first direction results in an upward motion of the rack and connected sucker rod pump. Rotation of the motor in a second direction opposite the first direction results in a downward motion of the rack and connected sucker rod pump. An electronic controller is operatively connected to the motor.

摘要： Methods and apparatus to determine operating parameters of a pumping unit for use with wells are disclosed. An example apparatus includes a housing and a processor positioned in the housing. The processor is to determine a rate at which to operate a motor of a pumping unit to enable a load imparted on a polished rod of the pumping unit to be within a threshold of a reference load or to enable a speed of the polished rod to be within a threshold of a reference speed.
