Definitions

  • This invention relates to secondary oil recovery systems and is particularly directed to means for generating steam within a borehole and recovering oil stimulated by said steam.
  • the Wagner device is a vast improvement over previous steam generators. However, there has still been considerable room for further improvement.
  • the generator is lowered down the borehole to the level of the formation to be treated, where it generates steam and injects the steam into the formation.
  • the steam generator is withdrawn from the borehole and is replaced by a pump which serves to produce the oil which was released by the steam.
  • a substantial period of time is required to accomplish this transfer and the steam-treated formation will be cooling down during this period. Consequently, much of the effect of the steam treatment is wasted.
  • the operations involved in lowering the steam generator into the borehole, subsequently removing it, and lowering the pump require much labor and downtime, whi-h add substantially to the cost of the process.
  • the advantages of the present invention are preferably attained by providing a secondary oil recovery system having a downhole steam generator and pump mounted substantially in parallel with each other so as to permit simultaneous positioning in the borehole and to permit independent operation of the steam generator and pump, so that the pump may be operated sequentially or simultaneously with the steam generator.
  • Another object of the present invention is to provide an improved method and apparatus for steam treating subterranian formations and recovering oil released from the formations by the treatment.
  • An additional object of the present invention is to provide apparatus for steam treating borehole formations and recovering oil released by the treatment without requiring intermediate transfer of apparatus into and out of the borehole.
  • a specific object of the present invention is to provide a secondary oil recovery system comprising a downhole steam generator and a pump secured substantially parallel with each other to permit simultaneous positioning in the borehole and means for operating the pump independently of the steam generator to permit the pump to be operated sequentially or simultaneously with the steam generator.
  • FIG. 1 shows a secondary oil recovery system, indicated generally at 2, located in a borehole 4 which penetrates a plurality of formations, as indicated at 6, 8, 10, and 12.
  • the borehole 4 may be enclosed by casing 14 along part of its length.
  • the formation 10 to be treated must either be increased or, if cased, the casing must be perforated.
  • the oil recovery system 2 comprises a steam generator unit 16, which may be similar to that of Wagner et al, cited above.
  • a water line 18, a fuel line 20 and an air line 22 connect the steam generator unit 16 with suitable supply sources, not shown, at the surface.
  • the output of the steam generator unit 16 is delivered through conduit 24, check valve 26, conduit 28, and exhaust nozzle 30 into the borehole 4 and the formation 10 to be treated.
  • a suitable pump 32 is mounted adjacent conduit 28 and is actuated from the surface by suitable means, such as sucker rod 34. The pump 32 draws oil from the borehole 4 through inlet 36 and conduit 38, and delivers the oil to the surface through conduit 40.
  • a suitable packer 42 secures conduits 28 and 38 together and serves to maintain the recovery system 2 at a desired location in the borehole 4 and to seal the borehole 4 so as to drive the steam into the formation 10 to be treated.
  • Additional coupling means 44 serve to secure the components together to form an integral unit.
  • the pump inlet 36 is positioned immediately adjacent the steam nozzle 30.
  • This arrangement is preferred for what is called “huff and puff" operation, wherein the steam generator 16 and pump 32 are actuated sequentially.
  • the pressure developed by the steam will drive oil out of the borehole 4 and, hence, will preclude simultaneous pumping while the steam generator 16 is operating.
  • pump 32 can be actuated in the same instant that the steam generator 16 stops.
  • production can be initiated while the formation 10 is at its hottest temperature and the oil is at its lowest viscosity.
  • a substantial quantity of oil can be pumped during the time heretofore required for transfer of equipment.
  • FIG. 3 shows an oil recovery system 2 which is similar to that of FIG. 1 except that the pump inlet conduit 38 is elongated so as to position the pump inlet 36 a substantial distance below the steam exhaust nozzle 30.
