Definitions

  • the present invention relates to an induction device for heating oil reservoir, in particular a heavy oil reservoir, and a method for the production of such an induction device.
  • the inductor must not be laid in electrically conductive materials, for example in a metallic cladding tube. In order to maintain the integrity of the inductor for a long time, the inductor must be protected as well as possible against mechanical stress and chemical influences.
  • a problem with the known electrical heating is induction cable with as little effort in the heavy oil reservoir relocate.
  • GRP glass fiber reinforced plastic
  • GRP glass fiber reinforced plastic
  • a disadvantage of this procedure is the introduction of the inductor. That is, it is difficult to introduce the inductor due to the relatively large length of the cladding tube in the cladding tube.
  • the inductor can tear off, for example, when pulling into the cladding tube.
  • the inductor rubs during installation and removal of the cladding tube, which can lead to damage both to the cladding tube, but also to the inductor.
  • the invention is in particular to use an inductor device for heavy oil, heavy oil or bitumen reservoirs.
  • the object is achieved by a manufacturing device for producing an induction device for heating a heavy oil reservoir, wherein the induction device of at least one cladding tube and at least one inductor, which is arranged within the cladding tube is formed.
  • the manufacturing device is characterized in that it has a spreading device for spreading apart the longitudinally slotted formed cladding tube.
  • the cladding tube is made of an electrically non-lightweight material, in particular of a plastic material.
  • the cladding tube is flexible.
  • the spreading device allows an inductor to be easily inserted into the longitudinally slotted cladding tube so that it is sheathed by the cladding tube.
  • the longitudinally slotted cladding tube can be spread apart, so that in the resulting opening portion of the inductor can be introduced.
  • the spreading device can be introduced at one end of the expandable cladding tube between the slot end faces.
  • the spreading device is preferably arranged stationary, so that the cladding tube can be guided past the spreading device. That is, the slot end faces of the cladding tube are continuously spread apart when passing the cladding tube on the spreading device, as in a zipper, in the thereby permanently changing position of the opening portion of the inductor can be introduced. That is, the inductor becomes relative to the spreading device during the movement of the cladding tube pulled into the cladding tube. The slot end faces of the cladding tube slide past the spreading device.
  • the inductor can be easily introduced into the cladding tube, that is, prior to placement in a heavy oil reservoir, easily overhead, for the formation of the induction device.
  • the inductor can be unrolled for example by a roller or a spindle and so be tracked continuously in the cladding tube.
  • the cladding tube can also be unrolled from a roll or spindle.
  • the cladding tube can also be composed of individual cladding tube pieces.
  • the longitudinally slotted cladding tube is opened by means of the spreading device and the inductor is continuously introduced into the cladding tube.
  • a great advantage of the manufacturing device is that for the production of an induction device, the inductor can be introduced in one piece in the cladding tube.
  • the spreading device has an opening for the passage of the at least one inductor.
  • the inductor is not introduced by the resulting opening portion in the cladding tube, but through the opening in the spreader.
  • the opening in the spreading device is preferably formed as a bore in the spreading device. This can be a circular hole.
  • the bore is slit-like, oval or egg-shaped. The dimension of the opening in the spreading device is such that an inductor can be passed through the opening with sufficient clearance.
  • the circumferential surface forming the opening at at least one or two places a Having rounded or beveled, so that the inductor can be pulled into the interior of the cladding tube as possible frictionless and edge-free through the opening of the spreader.
  • the spreading device may be provided in a production device that the spreading device has an oval or egg-shaped form or a substantially oval or egg-shaped form. This ensures that after insertion of the spreading device between the slot end faces of the cladding tube, the cladding tube easily passes by the spreading device, in particular can be pulled past it, the spreading device spreading apart the cladding tube.
  • the spreading device has guide grooves for receiving slot end regions of the cladding tube.
  • the guide groove ensures that the slot end faces or the open slot end regions of the cladding tube can be securely guided on the spreader. This means that the two slot end regions of the cladding tube are held by the guide groove of the spreading device, so that the slot end regions can not slip off laterally from the spreading device.
  • the guide grooves are formed on two opposite sides of the spreading device.
  • a circumferential guide groove is provided.
  • the spreading device preferably has a plate-shaped or annular shape.
  • the thickness of the spreading device is slightly larger than the wall thickness of the material of the cladding tube.
  • the spreading device of the production device is advantageously arranged in a stationary manner and the cladding tube is guided along under a spread apart by the spreading device. It is also conceivable that the cladding tube is arranged stationary and the spreading device is moved similar to a zipper along the slot of the cladding tube. So that the spreading device can be moved, it preferably has a gripping device. By gripping the spreading device can be pulled and so the cladding tube are gradually spread apart. During the movement of the spreading relative to the cladding tube of the inductor is drawn by the resulting opening portion or the opening in the spreading device in the interior of the cladding tube.
  • the production device has a merging device for firmly connecting the cladding tube along the slot end faces of the cladding tube. That is, after the introduction of the inductor by means of the spreading device in the cladding tube, the slit formed cladding tube can be firmly closed by means of the merge device, so that a spreading apart of the cladding tube is no longer possible.
  • the merging device is designed such that the two slot end faces of the cladding tube can be firmly connected to one another such that a closed cladding tube is formed. This ensures that the inductor is arranged in a particularly secure and protected manner in the cladding tube of the induction device.
  • the merging device of the production device can be designed such that the longitudinally slotted cladding tube can be closed non-positively. For example, this can be done by an additional sheathing of the cladding tube. Also, by the merger jig can be attached to the cladding tube, the cladding tube firmly hold together at the slot end faces. Also, a positive merging of the cladding tube is conceivable.
  • the merging device is designed for the material-locking connection of the slot end faces of the cladding tube.
  • the merging device may comprise an adhesive device or a welding device, by which the two slot end faces of the cladding tube can be glued or welded together.
  • the merging device of the manufacturing device is arranged after the spreading device, so that the induction device formed after introduction of the inductor into the cladding tube can be closed. Therefore, a production apparatus in which the merging device is designed for bonding or welding the slot end faces of the cladding tube is particularly preferred.
  • the above-described manufacturing device for producing an induction device for heating a heavy oil reservoir allows an above-day combination of inductor and cladding tube to a unit, that is, the induction device.
  • a major advantage of this is that the induction device, that is, the unit of inductor and cladding tube can be laid in a bore in a heavy oil reservoir.
  • Another advantage of the manufacturing device is that the inductor and the cladding tube can be manufactured separately. As a result, greater freedom for a redesign or a redesign of the components is achieved.
  • a time and effort savings can be achieved because only one laying process is required when installing the induction device.
  • the spreading device is introduced between the two slot end faces or open flanks of the cladding tube.
  • the cladding tube is spread apart in the region of the spreading device. Immediately before and / or behind the spreader, this results in at least one opening portion, through which the inductor in the Cladding tube introduced, in particular pulled, is.
  • the spreading device has an opening and in which the at least one inductor is introduced, in particular pulled in, through the opening in the spreading device into the spread-apart cladding tube.
  • This ensures a particularly safe introduction of the inductor into the cladding tube. That is, the inductor is not introduced into the cladding tube by a resulting opening portion, but through the opening in the spreader.
  • The preferably designed as a bore opening allows the inductor is not kinked or twisted.
  • Particularly advantageous is a method in which the inductor is inserted frictionless and free of edges through the opening of the spreading device in the interior of the cladding tube, in particular retracted, is.
  • the cladding tube is arranged stationary, a spreading device between the slot end faces of the cladding tube is introduced and after passing through an inductor by the spreading device, the spreading device is pulled parallel to the longitudinal axis of the cladding tube between the slot end faces of the cladding tube. In this case, the inductor is continuously drawn into the cladding tube.
  • the spreading device is fixed and the cladding tube, after the arrangement of the spreading between the slot end faces of the cladding tube, is guided past the spreader and thereby the at least one inductor through the opening portion of the cladding tube, in particular through the opening in the spreading , introduced into the cladding tube, in particular retracted, is.
  • an end of the cladding tube or the resulting induction device can be gripped by a gripping device and pulled past the stationary spreading device.
  • the slot end faces of the cladding tube by the merger device of the manufacturing device firmly together, in particular cohesively with each other, are connected.
  • a method is preferred, which is characterized in that the cladding tube is gripped by a pulling device and guided along the spreading device for threading the at least one inductor and on the merging device for firmly connecting the slot end faces of the cladding tube.
