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 deflected drain.
  • the regularity of the sweeping front is sometimes difficult to maintain due to heterogeneities of the reservoir, such as fractures or channels etc., modifications to the geometry of the drain or even disturbances linked to flows in the drain such as pressure drops .
  • a known method for sweeping a production area is to descend 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 area.
  • a production tube is lowered into the area to be activated.
  • a pump is interposed on the tube so as to create a vacuum.
  • An example of a pumping device is described, for example, in French patent application FR-A-2 631 379.
  • the vacuum created by such a tube is maximum near its lower end and, due to pressure losses, it decreases quickly with the distance so that the suction pressure quickly becomes insufficient to obtain a correct sweep 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 to promote, by creating a depression, the production of effluents outside of a production zone crossed by at least one deviated well or drain equipped with a casing tube provided with perforations distributed along of a production area.
  • the method comprises the descent into the well of a production tube associated with means for establishing a vacuum, the lower part of the production tube being provided with at least one opening, and it is characterized in that the '' the vacuum applied to a determined location of the well passing through said production zone is metered by moving said opening of the production tube to a position at a distance from this location of the well and / or by maneuvering means to vary more or minus the area of said opening, the distance and the area of the opening of the production tube being chosen so that the pressure drop which occurs as a result of this distance, with respect to the vacuum actually prevailing at opening of the production tube, makes it possible to obtain the desired vacuum.
  • a tube of production provided with a plurality of openings, at least part of them being provided with means for modifying their areas, and the openings are positioned at respective defined positions and / or the control of their respective areas, so that the combined pressure drops resulting from the distances between the openings and all the locations in the zone to be favored, make it possible to obtain said pressure distribution.
  • a production tube comprising a distribution of variable lateral openings along the tube.
  • a perforated casing tube such that the distribution of the perforations and / or their respective areas makes it possible to obtain a determined dosage of the depressions along a portion of the well.
  • 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 non-prepublished French patent application EN. 08/08/270.
  • the vacuum dp created is maximum in the vicinity of 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 sweeping 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.
  • 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 valves with sliding sleeves as described in published patent application FR 2 626 614.
  • valves 9 such as valves with sliding sleeves 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 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.
