摘要： A pump can include a plunger and a barrel, at one stroke extent flow being substantially restricted between the plunger and the barrel at spaced apart positions and a plunger interior passage in filtered communication with a fluid chamber between the positions, and at an opposite stroke extent the fluid chamber being in communication with the standing valve. A method can include displacing a plunger in one direction, thereby receiving filtered liquid into a fluid chamber, and b) displacing the plunger in an opposite direction, thereby transferring the liquid to a barrel interior passage. A system can include an actuator that reciprocates a rod string, and a pump including a plunger with a traveling valve, a barrel with a standing valve, and a filter that filters liquid which flows from a tubing string to a compression chamber disposed between the traveling valve and the standing valve.

摘要： Apparatus and methods are provided for rotating the sucker rod strings of pumping equipment and adjusting the vertical position of the sucker rod string. The apparatuses can include a threaded tubular rod carrier or spindle and a polished rod can run through the rod carrier, The rod carrier can be held in place along the rod with a locking mechanism on the upper and lower ends of the rod carrier. A rotator can surround the rod carrier, and the rotator can include a wheel and a main thrust bearing, the wheel being in threaded connection with the threads of the rod carrier and supported by the main thrust bearing. The rotation of the wheel relative to the rod carrier can result in vertical movement of the rod and the vertical movement of the rod can be accomplished without disengaging the means for fixing the rod carrier to the rod.

摘要： A controller for operating a rod pumping unit at a pump speed. The controller includes a processor configured to operate a pump piston of the rod pumping unit at a first speed. The processor is further configured to determine a pump fillage level for a pump stroke based on a position signal and a load signal. The processor is further configured to reduce the pump speed to a second speed based on the pump fillage level for the pump stroke.

摘要： A pumpjack includes a walking beam pivotally connected to a vertical support for oscillation in a generally vertical plane about a first axis. A first end of the walking beam is connected to a sucker rod string. A carriage is movably mounted to the walking beam to move back-and-forth along a length of a tail end of the walking beam. A pitman arm has a first end pivotally connected to the carriage for rotation about a second axis and a second end pivotally connected to a crank arm. A counterweight is mounted to the crank arm and a hydraulic ram is connected to the carriage to move the carriage back-and-forth along the walking beam and establish reciprocation of the sucker rod string.

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： A downhole pumping assembly has a tubing string with plural barrels which are arranged in-line with the tubing. The tubing string has a seating location adjacent to each barrel. A standing valve arrangement, which includes a standing valve and a seating device, is located with the standing valve adjacent to the lower end of one of the barrels. A plunger has a traveling valve that is located for reciprocation within the one barrel. The plunger has a clearance with each of the barrels so as to form a fluid seal. The plunger reciprocates inside the barrel so as to lift fluid to the surface. Over time, the barrel will exhibit wear. Instead of pulling the entire tubing string to replace the barrel, the standing valve and the plunger are relocated to one of the other barrels located in the tubing string and reciprocation is resumed to resume pumping.

摘要： The invention pertains to oil production pumping equipment in particular to submersible downhole pumps with rod drives to simultaneously and separately lift reservoir fluids to the surface from two reservoirs of a single well. The downhole pump assembly comprises a drive, upper and lower oil-well sucker-rod pumps each connected with its own rod string. In addition to this the unit is equipped with the body, crossbar and joint hollow rod string the latter being attached to the upper part of the crossbar to the bottom of which the rod strings of the upper and lower oil-well sucker-rod pumps are fixed, moreover, the rod string of the upper oil-well sucker-rod pump being made hollow and interconnected with the hollow plunger of the upper oil-well sucker-rod pump and the channel in the crossbar with the joint hollow rod string, and the rod string of the lower oil-well sucker-rod pump is installed between the cylinder of the upper oil-well sucker-rod pump and the downhole pump assembly body, moreover, the upper oil-well sucker-rod pump being offset from the longitudinal downhole pump assembly body axis. Coaxiality of the lower oil-well sucker-rod pump is achieved through the use of the rod crossover shoe, S-shaped rod and non-central pipe sub. The lower plunger pump rod has a shaped cross-section. As a result a standard pumping unit and two oil-well sucker-rod pumps are used and both enhanced reliability of the downhole pump assembly and increased overhaul life of its operation are achieved.

摘要： A stress and torque reducing tool has a plunger that reciprocates inside of a body. The tool is connected between the pump and the sucker rod string and reduces stress transmitted therebetween. The body and plunger have longitudinally extending surfaces located at the plunger upper end portion, which surfaces cooperate and limit rotation of the body with respect to the plunger. An upper fluid port is located in an upper end of the body, while one or more lower fluid ports are located in a lower end of the body.
