| 121 | Wiper and seal assembly for a pump | US14530461 | 2014-10-31 | US10077616B2 | 2018-09-18 | John Edward Stachowiak, Jr. |
| A tubing pump includes a seal housing insertable into a production string of tubing with a seal assembly mounted in an interior of the seal housing. The assembly includes at least an upper seal and seal holder and a lower seal and seal holder, each seal energizable by fluid to provide a fluid-tight seal around a reciprocating tubular member. The seals and holders are isolated from each other in a manner whereby the lower seal remains un-energized until the seal above it fails. | ||||||
| 122 | Pump jack system and method | US14588276 | 2014-12-31 | US10047739B2 | 2018-08-14 | Minhao Yin |
| 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. | ||||||

| A sucker rod string improved by the use of wear resistant, high temperature resistant, fiber-reinforced phenolic composite materials as centralizing guides on sucker rods and couplings, both molded on the rod and prepared as snap-on couplings for in-the-field use, and on magnet rod inserts, both rod box and pin magnet rod inserts, in which the thermosetting composites are used as sleeves, encapsulating housings, and centralizing guides. The magnet rod inserts and couplings are designed to be machined so that worn phenolic composite can be removed and replaced with fresh composite without removing or damaging the magnet. Processes are disclosed for integrating composite thermoset molding into sucker rod, coupling, and magnet rod insert manufacture and for refurbishing used components of a sucker rod string. | ||||||
| 124 | DOWNHOLE OCCLUDER, PRESSURIZED SUCKER ROD AND OPERATION TECHNIQUE TO REPAIR OIL PIPES | US15608581 | 2017-05-30 | US20170328169A1 | 2017-11-16 | Xiangsheng LV; Gangyao LI; Zhongxiang ZHAO; Haijun LUAN; Yimin ZHANG; Junfeng LV; Tingde FENG |
| This invention discloses a downhole occluder for oil wells. A sealing socket and a positioning flange with sealing surfaces are set up inside an oil pipe. An oil sucker rod pump is installed inside the tubular column which mounts on top of the sealing socket. A sealing surface of a sealing flange on the rod pump mounts with a sealing surface of the sealing socket on the tubular column. Outer oil inlet borings are placed at the wall of oil tubular column underneath the positioning flange. An inner pipe is installed inside this section of tubular column. Place inner oil inlet borings on the inner pipe wall corresponding to outer oil inlet borings on the tubular column. Sealing grooves are placed underneath the inner oil inlet borings on the inner pipe wall. Sealing rings are placed in the sealing grooves to seal the inner wall of tubular column. Top of inner pipe is connected to oil sucker rod pump through connecting coupler. Bottom end of tubular column is occluded. The structure of this invention is simple, reasonable and reliable to perform the well maintenance works of pressurized sucker rod and oil pipe. It brings the convenience to repeatedly occlude the pressure under the well to result in a safe, highly efficient, environmental and energy saving production. | ||||||

| 129 | Polished Rod Alignment System | US14601534 | 2015-01-21 | US20160208565A1 | 2016-07-21 | Clarence Alvin Bolstad, JR. |
| A polished rod alignment system for correcting the misalignment of a polished rod to the stuffing box. The present invention generally includes a first member, a second member, a first alignment member, and a second alignment member. The second member is secured over an oil well, such as to a blowout preventer. The first and second alignment members are secured over the second member, with the alignment members being adapted to rock with respect to each other due to each having inverted sloped portions. The first member is secured over the alignment members and is adapted to receive a stuffing box. A polished rod may extend through the entirety of the present invention. By adjusting bolts securing the first and second members together, and by action of the alignment members, the polished rod and stuffing box may be brought back into alignment if misalignment occurs. | ||||||
| 130 | On-Off Tool for Sucker Rod String | US14946898 | 2015-11-20 | US20160208564A1 | 2016-07-21 | John E. Stachowiak; Brandon M. Page |
| An on-off tool for latching a sucker rod to a plunger rod has a housing, a pawl, guide pines, and a key. One end of the housing is connected to the sucker rod, and an interior of the housing defines a key slot terminating at a seat inside the interior. The pawl is disposed in the interior of the housing and is biased longitudinally preferably by disc springs. Bearings in the form of elongate pins are engaged between the pawl and the housing and dispose longitudinally in slots to guiding longitudinal movement of the pawl in the interior and preventing rotation of the pawl. The key has a head at its distal end that is passable through the key slot, interlockable with the pawl, and seatable on the seat. The key's head preferably defines a waist thereabout to provide the head with greater load bearing surface to engage the housing's seat. | ||||||
| 131 | Coupling Mounted Spin-through Rod Centralizer | US14879148 | 2015-10-09 | US20160177635A1 | 2016-06-23 | William Bruce Morrow |
| A spin-through rod centralizer consisting of a stator constructed of plastic, or other appropriate material, which is mounted on the rod coupling which provides the bearing surface for rotation of the coupling within the stator. The stator, which is free to rotate on the rod coupling and, hence, would move freely axially along the coupling, is restrained from such axial movement by two steel “washers” that are captured between the rod shoulders and the coupling when the connection between two rods is made up. The washers are slightly larger in diameter than the coupling and thereby keep the stator located on the coupling, yet do not restrict the relative rotation between the coupling and the stator. This coupling mounted centralizer will not interfere with rod string make-up when using equipment in common use. An alternative configuration uses a coupling with a shoulder at one end that acts as one of the “washers” to restrain the stator from axial movement. | ||||||

The assembly also includes an alignment pin extending at least partially within the first and second pawls to maintain alignment and to facilitate movement of the pawls along the common central axis. | ||||||

| 138 | Multi-tasking rod guide | US13437920 | 2012-04-02 | US08967247B2 | 2015-03-03 | Douglas Ray Dickinson |
| A multi-tasking downhole rod guide for centralizing a downhole pump rod production tubing within production tubing, while simultaneously reducing abrasion and deterioration of the production tubing and engendering auxiliary pump-boosting functions. The rod guide is configured with an elongate helix having a continuous trough-like channel through which hydrocarbons flow upwardly under high pressure. As the pressurized hydrocarbons flow through a succession of plates at each equidistant helical level, the elongate helix rotates synchronously with the upwardly flowing hydrocarbons within the production tubing string. | ||||||
