Definitions

  • the present invention relates to a method for promoting, by creating a depression, the production of effluents from a production zone crossed by at least one deviated well or drain, such as an oil zone.
  • deviated well designates any well of which at least part is substantially horizontal or slightly inclined relative to the horizontal.
  • One of the advantages of deviated wells is to allow better sweeping of the petroleum effluents contained in the formations crossed and therefore to improve recovery.
  • Optimal recovery for a given scanning mechanism, is obtained when the scanning front moves parallel to the deviated drain.
  • the regularity of the sweeping front is sometimes difficult to maintain due to heterogeneities of the reservoir, such as fractures or channels etc., changes in the geometry of the drain or even disturbances related to flows in the drain such as pressure drops .
  • a known method for sweeping a production area is to lower a pumping device there to suck out the effluents when the pressure in the formation becomes insufficient.
  • the deviated well which crosses it is equipped with a casing or casing tube which is perforated in its part which crosses the production zone.
  • a production tube is lowered into the area to be activated.
  • a pump is inserted on the tube to create a vacuum.
  • An example of a pumping device is described for example in the French patent application EN. 08/08/270.
  • the vacuum created by such a tube is maximum near its lower end and, due to the pressure drops, it decreases quickly with the distance so that the suction pressure quickly becomes insufficient to obtain a correct sweeping of the production area.
  • the layer containing the oil is relatively thin. It is bordered on one side by an accumulation of gas or an aquifer. It can still be between an accumulation of gas and an aquifer. Too strong a vacuum at the outlet of the tube has the effect in this case, also to bring the gas or water from the adjacent layers.
  • the method according to the invention makes it possible, by creating a depression, to promote the production of effluents by a production zone crossed by at least one deviated well or drain, into which a tube is lowered, the lower part of which is at least provided with openings.
  • the extent of the depression is selectively varied in at least one location of the tube by a selective modification of the position of the openings where the depression is applied relative to said location and / or the area application openings of this depression.
  • the method includes regulating the vacuum in at least one location of the well by adapting the pressure drop undergone by the effluents produced between this location and said openings.
  • the appropriate pressure drop is obtained at said location, for example by using a tube provided with at least one opening for applying vacuum and by varying the length of the path between said location and an opening of the tube and / or the section of said opening.
  • the tube can also be provided with a plurality of openings distributed over its length and means for varying the section of at least part of the openings, the method comprising in this case the selection of at least at least one of said openings the distance of which at said location and / or the section are chosen to obtain at said location a depression.
  • the method may include the use of a perforated suction tube and / or a perforated casing, the distribution of the perforations and their areas being chosen to obtain a determined depression distribution.
  • the method according to the invention may include the use of a suction means such as a pumping assembly, to increase the vacuum applied to the training.
  • a suction means such as a pumping assembly
  • the method relates to the scanning of a producing area by creating a depression in a formation 1 put into production.
  • the formation is crossed (Fig. 2) by a deviated well or drain 2, the lower part of which is horizontal or at a slight inclination relative to the horizontal.
  • the well is generally provided with a casing or casing tube perforated 3 in its part which crosses the production zone.
  • a production tube 4 is lowered into the zone to be activated.
  • a pump 5 is interposed on the tube so as to create a vacuum.
  • An example of a pumping device is described for example in the French patent application EN. 02/02/270.
  • the vacuum dp created is maximum near the lower end 6 of the tube 4 (Fig. 2) and, due to the pressure losses, it decreases with the distance d (Fig. 2), so that the pressure d Aspiration becomes insufficient to obtain a correct sweep of the production area.
  • a first embodiment of the method consists in moving the lower end of the tube 4 opening into the production area, so that at any location of the drain, a sufficient vacuum is obtained to favor the arrival of oil with a good sweep of the area, without creating other unwanted inflows.
  • play is made on the relative position of the locations of the drain relative to the suction opening.
  • a second embodiment of the method consists in using a tube 7, the part of which passes through the production area is provided with a plurality of openings 8 (FIG. 3) with selective opening.
  • a tube provided with lateral openings which can be masked and unmasked at will by action on valves 9 such as sliding jacket valves as described in published patent application FR 2 626 614.
  • valves 9 such as sliding jacket valves as described in published patent application FR 2 626 614.
  • the openings 8 can be discovered either partially (valve 9A) or entirely (valve 9B).
  • the selective opening of one of the valves has the effect of locally increasing the vacuum (Fig. 4) and of regulating the sweeping in the vicinity of the new opening.
  • the first is the distance separating this location from the suction opening 6,8 and one can choose that of the lateral openings of the tube which is at the suitable distance.
  • the second factor is the suction area and it can be modified by opening one or more of the valves 9 and / or by modifying the number of open valves.
  • a production tube 10 is perforated over a part of its length with a distribution of lateral perforations 11 along the tube.
  • the density of perforations and / or their areas are chosen to obtain a distribution of depressions adapted to the configuration of the well.
