Definitions

  • the present invention relates to a method for stimulating an underground zone by delayed injection of pressurized fluid from a neighboring zone by means of a deflected drain passing through an intermediate layer which is not very permeable.
  • a deflected drain passing through an intermediate layer which is not very permeable.
  • the method according to the invention more particularly makes it possible to stimulate the production of an oil zone separated from an underlying zone containing a pressurized fluid, such as an aquiferous zone or possibly an oil zone.
  • Various techniques well known to specialists are used to stimulate the production of oil zones.
  • One of them consists essentially of injecting a pressurized fluid into the production formation, capable of draining the stagnant oil in the rocks due to its viscosity.
  • the fluid used is for example pressurized water injected by drains drilled through the formation. It can also be water existing deep in the production basin itself in the form of an underlying aquifer.
  • the aquifer In certain types of basins, the aquifer is located beneath the oil zone and separated from it by a layer which is not very permeable due in particular to the presence of heavy and very viscous hydrocarbon products ("tarmat").
  • tarmat heavy and very viscous hydrocarbon products
  • the method according to the invention makes it possible to stimulate the production of an underground zone by delayed injection of a fluid coming from a neighboring zone separated from the first by an intermediate layer which is not very permeable, avoiding the drawbacks mentioned above.
  • It is characterized in that it comprises the drilling of at least one deflected drain in said intermediate layer and the delayed opening by fracturing of the intermediate layer, of at least one communication path connecting the neighboring area to the underground area , so as to promote the drainage of said underground zone by the pressurized fluid.
  • the method includes, for example, making from drain, fracturing between an oil zone and an underlying aquifer zone.
  • the method also includes, for example, carrying out from the drain, fractures making an oil zone communicate with an underlying second oil zone.
  • the drain can be pierced in an intermediate layer which is not very permeable. It can also be drilled in a non-oil-bearing intermediate layer.
  • the device according to the invention is characterized in that it comprises a pipe disposed in a deviated drain pierced in the intermediate layer, said pipe being pierced with openings over part of its length, shutter blocks for isolating portions of the pipe on the part thereof pierced with openings, and means for applying hydraulic pressures capable of fracturing the intermediate layer and putting in communication during the production period, the two zones of share and other of said intermediate layer.
  • the oil zone Z1 produces oil by at least one production well P1.
  • This well can be vertical as shown in FIG. 1 or alternatively be horizontal.
  • a very low permeability layer L there is a neighboring zone containing a fluid under pressure.
  • the pressure of this fluid is higher than the pressure prevailing in the production zone Z1 because the neighboring zone is at a greater depth.
  • This fluid can be water or even a petroleum fluid.
  • the intermediate layer L can for example be an area made almost impermeable due to the presence of very heavy and viscous hydrocarbon products.
  • This layer L can also be of a non-oil type.
  • the method according to the invention comprises drilling from the surface S of a deviated drain D (horizontal or slightly inclined relative to the horizontal) so as to remain in the intermediate layer.
  • a deviated drain D horizontal or slightly inclined relative to the horizontal
  • the drain D is drilled, it is provided with a casing or casing C over its entire length.
  • Known sealing means make it possible to close the annular space between the casing and the drain.
  • the casing C is provided with lateral openings O putting the crossed formations in communication with the interior of the drain D.
  • the drain can be drilled at any time, before the production of the oil zone Z1 or possibly during the production period.
  • fracturing operations are carried out on the intermediate layer from the previously pierced drain D.
  • a tube (not shown) communicating the confined part with a hydraulic system, a fluid is applied under sufficient pressure to fracture the walls until the establishment of communication channels F between the two zones Z1 and Z2.
  • the previous sequence of operations may be repeated at several different points in the drain, so as to widen the fractured area.
  • a blocking block B3 is installed in the casing so as to isolate the drain from the outside environment.
  • the fluid in this case the water of zone Z2, being at a higher pressure and the drain being confined by the obturation block B3, the water enters zone Z1 by the fractures F of casing C and flushes out the oil accumulated in the formation.
  • the drain D is arranged so that it can be used as a production well.
  • the casing C is provided in its part which crosses the production zone Z1, with another portion of length d2 provided with lateral orifices.
  • This other casing portion d2 is, depending on the case, more or less distant from the portion d1 through which the water coming from the zone Z2 can enter and laterally offset with respect thereto.
  • a shutter member B4 Between the two portions d1 and d2 is disposed a shutter member B4 whose closure can be triggered from the surface installation.
  • the length portion d1 of the casing is fractured, in the same way as in the previous embodiment and the organ is closed B4 so as to isolate one from the other the two parts d1 and d2 of the casing.
  • Water from the underlying zone penetrates by fracturing into the production zone Z1 and drives the oil towards the production wells and in particular towards the part d2 of the casing C open to the external environment. The drain thus participates in production.
  • the method according to the invention thus makes it possible to best use the high pressure fluid available in situ for the purpose of stimulating oil production.
  • the position of the vertical and / or horizontal production wells relative to the deflected drains D or vice versa of the drains with respect to the wells according to the order in which they will have been drilled is chosen according to the rules of the art so as to optimize oil production .
