    摘要： A method and a tool to consolidate a wellbore by displacing conventional cement slurry or any other settable fluid, without any permanent casing. A bladder is inflated inside the bore to act as a mould and to form an annulus that can be filled by cement slurry or any other settable fluid. When the cement or the resin is set, the form is retrieved by straight pull; leaving a cement or resin sheath to support the formation without requiring any re-drilling. The sheath can be perforated if necessary (in the producing zone).
    Applications include without limitations temporary cementation of mono-diameter wells, through-tubing repair of an open hole, or cementation of a slotted liner in water, oil or gas wells.

    摘要： The invention discloses a method of treatment of a near zone and/or a far zone of a well comprising a wellbore and wherein the method comprises the steps of: (i) placing inside the wellbore a tube which is permeable to a material, so that the tube forms an annulus with the wellbore, the first zone being inside the annulus and the second zone being beyond the wellbore; (ii) placing inside the tube a setting section surrounded by a sleeve, the sleeve being expandable and impermeable to the material; (iii) inflating the sleeve so that the sleeve is in contact with the tube, ensuring for a first zone of the tube impermeability to the material, but leaving a second zone permeable to the material; (iv) pumping a treatment fluid to the zones, the treatment fluid passing through the second zone still permeable to the material; and (v) treating the near zone and/or the far zone with the treatment fluid. Also, the invention discloses the associated apparatus for treatment of a near zone and/or a far zone of a well according to the method.

    摘要： The invention provides a method of treatment of a zone of a well, wherein inside the well, a wellbore in a formation is filled with a tube which is permeable to a material, the tube forming an annulus with the wellbore, and the zone being localized beyond the tube in the annulus and/or in the formation, and wherein the method comprises the steps: (i) placing inside the tube a setting section surrounded by a sleeve near the zone to treat, the sleeve being expandable and impermeable to the material; (ii) inflating the sleeve so that the sleeve is in contact with the tube near the zone to treat, ensuring for a first zone of the tube impermeability to the material, but leaving a second zone permeable to the material; (iii) pumping a treatment fluid to the zone to treat, the treatment fluid passing into the annulus via the second zone still permeable to the material; and (iv) treating the zone to treat with the treatment fluid.
    Also, the invention provides an apparatus for treatment of a zone of a well, the zone being localized beyond a tube placed inside the well and forming an annulus with a wellbore, the tube being permeable to a material, and the apparatus comprising: (i) a setting section surrounded by a sleeve, the sleeve being expandable and impermeable to the material; (ii) an inflating means for inflating the sleeve, the inflating means ensuring that the sleeve is in contact with a first zone of the tube so that the first zone of the tube becomes impermeable to the material; and (iii) a delivery opening for delivering a treatment fluid to the zone to treat, the delivery opening ensuring that the treatment fluid passes into the annulus via a second zone still permeable to said material.
