摘要： A pump jack system for vertically reciprocating a downhole pump in an oil and gas well. The pump jack system includes a cylinder assembly having a drive cylinder and two balance cylinders. A piston in the drive cylinder may be used to provide an upstroke of a sucker rod string of a downhole pump. The pistons in the balance cylinders may be used to provide a downstroke of the sucker rod string. Lower chambers in the balance cylinders counterbalance the lifting and lowering of the piston in the drive cylinder. The pump jack system also includes an accumulator for maintaining a relative constant fluid pressure in the lower chambers of the balance cylinders.

摘要： A switching assembly for a hydraulic pump jack has a non-magnetic cylinder and a piston that is reciprocally movable within the interior bore of the cylinder. The piston has circumferential sealing means to engage the interior surface of the cylinder, and carries a magnetic element. A fluid source supplies a working fluid to the cylinder to move the piston within the cylinder. At least one magnetic sensor having a unique sensor value is externally mounted adjacent to the non-magnetic cylinder and senses at least a top of a piston stroke and the bottom of the piston stroke. A controller receives signals from the magnetically-actuated sensors as the magnetic element carried by the piston comes in proximity with and influences the at least one magnetic sensor. The controller controls piston positioning by selectively controlling the flow of working fluid to the cylinder.

摘要： An apparatus and method for imparting an angularly rotational movement. The apparatus includes a cylinder having an internal portion, a rod operatively positioned within the internal portion of the cylinder, a first bearing operatively positioned about rod; a second unidirectional bearing operatively positioned about the rod and a motion program for selectively inputting incremental radial motion to the rod. The apparatus may also include a force generator for linearly moving the rod in a linear axial motion along an axis of the cylinder.

The piston has circumferential sealing means to engage the interior surface of the cylinder. A magnetic element is carried by the piston. A fluid source supplies a working fluid to the cylinder, wherein the piston is moved by injecting working fluid into the cylinder. At least one magnetic sensor is externally mounted adjacent to the non-magnetic cylinder that senses at least a top of a piston stroke and the bottom of the piston stroke. A controller receives signals from the magnetically actuated sensor as the magnet element carried by the piston comes in proximity with and influences the at least one magnetic sensor.

摘要： A system and method to determine linear and approximate rotational position of a reciprocating and rotating hydraulic cylinder. The system uses two magnetic rings offset a distance, each ring having a continuous arc of magnetic material terminating in a blind zone, where the blind zone produces a magnetic field substantially different from the continuous arc region. The magnetic fields are used to detect location and rotation by an magnetic sensor that interacts with the magnets and blind zone.

摘要： A method of measuring a density of two liquid phases in a mixture with a gas phase. The three phase mixture is fed into an inlet vertical column of a flow loop where the gas phase is separated from a liquid mixture of the two liquid phases. The gas phase rises to an upper section of the inlet vertical column, while the liquid mixture flows to a lower section. A differential pressure of the liquid mixture is measured in the lower section. A density of the liquid mixture is calculated using the measured differential pressure of the liquid mixture. A volume or mass percentage is determined for each of the liquid phases in the liquid mixture. A volumetric flow rate is measured. A volumetric flow rate and accumulated volume of each liquid phase is calculated based on the volume or mass percentage of that liquid phase in the liquid mixture.
