Definitions

  • the present invention relates to a reverse rotation for borehole pumps.
  • Canadian Patent CA 2 331 915 C discloses an apparatus and method for securing and maintaining a boom in a wellbore.
  • the device is located below the lantern and above the borehole.
  • the four holding elements for the linkage are arranged with an offset of 90 °, so that each holding element holds the linkage from one side.
  • the holding elements each consist of a jaw and a screw, with which the jaws are pressed against the linkage. When the jaws rest against the linkage, there is a gap between each jaw.
  • Canadian Patent CA 2 349 988 C describes a device for holding and fixing a polishing rod in oil feed pumps.
  • the device is installed in the drive train of the oil pump and connected via two flanges with this.
  • two clamping jaws are pressed onto the polishing rod via threaded bolts.
  • the jaws are separated by springs and pressed against the inner wall of the device.
  • a sleeve for guiding the polishing rod is inserted.
  • the invention has for its object to provide a reverse rotation, with which the drive train of a borehole pump, when not in operation, can be secured against rotational movements.
  • the reverse rotation lock for downhole pumps, wherein the reverse rotation lock according to the invention is arranged in a drive head.
  • the reverse rotation lock comprises a housing and a clamping tool for securing a polishing rod.
  • the clamping tool has at least two replaceable contact elements with which the polishing rod is detachably fixable.
  • the contact elements are releasably inserted in a respective holder. Each contact element is connected by at least one screw to the holder.
  • the contact elements are made of a spark-free and pressure-resistant material. Preferably, the contact elements are made of bronze, brass or copper.
  • the clamping tool can be adapted by different sized contact elements on different polishing rods with different diameters.
  • the contact elements with different inner diameters can be inserted into the holders of the clamping tool, so that different contact elements can be selected depending on the diameter of the different polishing rods. It is clear to a person skilled in the art that the clamping tool can also be adapted to polishing poles which have changed their diameter during operation of the borehole pump by means of various contact elements.
  • the side of the holder which is opposite to the contact element, is provided with a groove for receiving a set screw.
  • the brackets are movable by means of the screws inside the housing.
  • Each set screw is capped at the side facing away from the holder.
  • the caps are applied to the set screws, if the contact elements do not rest against the polishing rod.
  • the borehole pump is ready to start. If the contact elements are in contact with the polishing rod, the adjusting screws are screwed into the housing of the reversing safety device far enough so that it is not possible to apply the caps to the adjusting screws.
  • Another advantage of this approach is that the threads of the screws are protected in normal operation by the caps from dirt and weathering.
  • the caps are provided with contacts that indicate the state of relaxation of the reverse rotation. Furthermore, the caps are in each case via a connecting cable with a controller in contact, which prevents a start of the borehole pump in the absence of signal. This ensures that the borehole pump can only be started when the contact elements are detached from the polishing rod and thus this is not blocked.
  • the contact elements are pressed by means of actuators to the polishing rod, held on the polishing rod and removed from the polishing rod.
  • actuators are used as actuators, screws or hydraulic actuators.
  • the release is realized by contacts, which are arranged in caps, which are screwed after removing the contact elements of the polishing rod on the screws.
  • this object can be achieved by magnetic switches which are moved via the hydraulically operated cylinder.
  • Fig. 1 shows the position of the reverse rotation in the drive head.
  • Fig. 2 shows the reversing device according to the invention in detail.
  • Fig. 3 shows a perspective view of the reverse rotation.
  • Fig. 4 shows a reverse lock with electronic collision.
  • Fig. 5 shows the security system of the reverse rotation in detail.
  • Fig. 1 shows the position of the reverse rotation lock 20 in the drive head 10.
  • the reverse rotation lock 20 is disposed in the upper region of the lantern 14.
  • the reverse rotation lock 20 as well as by the drive head 10 extends the polishing rod 12.
  • the motor 18 is mounted on the drive head 10.
  • Fig. 2 shows the reverse rotation lock 20 according to the invention in detail.
  • the reverse rotation lock 20 consists of a housing 22. Inside the housing 22 is the clamping tool 24 for securing the polishing rod 12.
  • the clamping tool 24, consists in the embodiment shown here of two brackets 28, in which the contact elements 26 are introduced.
  • the contact elements 26 provide the connection between the reverse rotation 20 and the polishing rod 12 ago.
  • the contact elements 26 are connected by the screws 30 releasably connected to the brackets 28.
  • the contact elements 26 opposite sides of the brackets 28 grooves 32 are introduced, in which engage the screws 34.
  • the contact elements 26 are pressed against the polishing rod 12 or released from this.
  • caps 36 are arranged. These caps 36 are applied to the screws 34, when the contact elements 26, by turning back the screws 34 are no longer in contact with the polishing rod 12.
  • Fig. 3 shows a perspective view of the reverse rotation lock 20.
  • the brackets 28 are introduced. Inside the brackets 28, the contact elements 26 can be seen, which are fixed with the screws 30 releasably in the brackets 28. Furthermore, the grooves 32 can be seen, in which engage the screws (not shown).
  • the caps 36 can be seen, which cover the screws 34 after removing the contact elements 26 of the polishing rod (not shown). The caps 36 are connected via the fuses 37 to the housing 22 so that they can not be lost when not in use.
  • Fig. 4 shows a reverse lock 20 with electronic collision.
  • the caps 36 are provided with contacts 38, which are connected via connecting cable 42 to a controller 40.
  • the controller 40 is mounted in this embodiment, as well as the caps 36 on the housing 22 of the anti-rotation device 20.
  • Fig. 5 shows the security system of the anti-rotation lock 20 according to the invention in detail.
  • the adjusting screws 34 are arranged laterally. With these screws 34, the position of the brackets 28 and thus the contact elements 26 is changed. When the contact elements 26 have been removed from the polishing rod (not shown), the adjusting screws 34 protrude beyond the housing part. Now, if the caps 36 are screwed onto the screws 34, 38 is between the heads of the screws and the contacts 38 made a connection. This connection becomes one closed electrical circuit, which makes it possible to start the drive of the borehole pump.
