Definitions
- the present invention relates to a method of lining a well or a pipe, for example a casing, having a portion to be treated in order to make it tight, in particular to repair and / or to plug.
- the boreholes for water collection are drilled into the ground and generally comprise a continuous jacket, or casing, made by a succession of relatively short steel cylindrical tubes (of the order of 6 m to 12 m for example) welded or screwed end to end to each other.
- This casing once cemented against the natural wall of the well provides a seal over the entire height of the well, to prevent contamination between the various layers of land. Over time it happens that a portion or the entire wall of the casing must be sealed, especially when it has been degraded, for example by premature wear and / or corrosion, or when the perforations for the passage of the water must be clogged, especially because they produce undesirable fluids that may pass through the casing wall and penetrate inside it.
- This expansion is usually done using a mandrel.
- a mandrel For this purpose use is made of a rigid cylindrical mandrel, for example steel, provided with a frustoconical end portion or ogive (shell shape). The diameter of the cylindrical portion corresponds to the inside diameter that it is desired to give to the liner.
- the mandrel is moved continuously inside the tube constituting the lining, axially, of an end thereof, by thrust or axial traction.
- the frustoconical or ogive portion is used to gradually and radially push back the wall of the tube, so as to press against the inner surface of the casing.
- some mandrels are rotatable, or provided with rollers or rotating rollers.
- a disadvantage of this technique is that the mandrel has a well defined, invariable cross section, so that there is a problem when it passes through portions of the casing that do not have a cylindrical section of strictly matched diameter; these include narrowed portions and / or non-circular section, for example ovalized.
- a mandrel of this type is for example the subject of US 6,688,397.
- this kind of tool is relatively complex and fragile; moreover, when it is dilated, interstices are formed between the different segments which are not in contact with the wall to be expanded, so that the final section obtained has a relatively irregular shape.
- a tube of long length, formed of sections of tube previously fixed end to end, is introduced into the well or pipe to be lined, after which the radial expansion of the tube, over its entire length, of such so that its wall comes to apply against that of the well or the pipe; this expansion is performed by a succession of successive positions of the inflatable bladder along the tube with, in each position, a crimping operation by inflating the bladder, then deflating it to bring it to a position adjacent to the previous, and so on all along the tube.
- the maximum number of expansion operations of such an inflatable bladder tool is generally about fifty.
- the aim of the invention is to overcome these difficulties by proposing a method that makes it possible to jack a large area of the casing quickly and economically.
- the invention can be applied not only to a casing as described above, but also to any well dug in the ground or to any pipe, buried or not, and that is why it is stated, in the description and the claims to follow, the lining of a well or pipe, the latter may be a casing or an open well, or any other duct, vertical, horizontal or oblique, rectilinear or curved.
- the subject of the invention is therefore a method of lining a well or channel, for example a casing by means of an inflatable bladder, all or only certain portions of the well or the pipe in front of it. be treated, especially repaired and / or clogged (s).
- a cylindrical tube (possibly made up of sections of tube previously fixed end to end) is introduced into the well or into the channel to be lined, after which the tube is expanded radially by means of a tube. inflatable bladder, so that the wall of the tube comes to apply against that of the well or the pipe.
- this expansion is carried out, not by proceeding step by step, but by moving the bladder previously inflated axially and continuously inside the tube, on a stroke corresponding to the length of tube to be expanded.
- the deformability of the membrane constituting the bladder and the fluidity of the hydraulic fluid ensuring its inflation that the cross section of the bladder is not fixed, unlike that of a movable mandrel. It can permanently adapt to the effective profile of the well or pipe to be lined, so that the liner can marry parts of narrowed section, enlarged and / or imperfectly cylindrical (including oval).
- the liner can marry parts of narrowed section, enlarged and / or imperfectly cylindrical (including oval).
- the inflatable bladder is positioned in the deflated state inside the tube facing a portion of the end of the tube to be expanded, after which it is inflated so as to radial expansion of this end portion and then moving it in the inflated state, axially and continuously, towards the opposite end;
- certain zones of the tube are expanded, which are separated by unexpanded zones in which the bladder is passed to the deflated state.
- use is made of an inflatable bladder provided with a filamentary reinforcement with variable winding, which gives it, in the inflated state, a predetermined shape and calibrated dimensions;
- an inflatable bladder provided with a protective shield consisting of adjacent flexible lamellae; the inflatable bladder is moved in the tube by traction by means of a rod; the inflatable bladder is moved in the tube by axial thrust, under the action of a fluid under pressure.
- Figure 1 is an axial sectional view of a shaft or pipe to be lined.
- Figures 2 to 6 are schematic views illustrating various steps of the method of the invention, for the lining of the well or the pipe of Figure 1.
- FIG. 7A is an axial sectional view of a well or channel to be lined which has a zone of enlarged section.
- Figure 7B illustrates the lining operation of the well or pipe of Figure 7A.
- Figure 8A shows a liner having alternating expanded portions with unexpanded portions.
- Figure 8B illustrates the operation for making the liner of Figure 8A.
- Figures 9 and 10 are cross-sectional views of a well or pipe of non-strictly circular cross section, respectively before and after lining.
- Figures 11 and 12 are diagrams of a hydraulic liner, inflatable bladder, degree and expansion zones calibrated respectively before and after expansion.
- Figures 13 and 14 are perspective views of a hydraulic liner tool, inflatable bladder equipped with a protective shield, respectively before and after expansion.
- FIG. 1 represents a borehole of water catchment, of vertical axis, dug in the ground S.
- Its wall C of circular section, or approximately circular, is rough or consists for example of a deteriorated pipe (or casing), that it is desired to seal by lining it internally with a liner.
- the scale in order to facilitate reading, the scale has been substantially enlarged in the radial direction of the duct (perpendicular to the axis of the borehole) with respect to the scale used in the axial direction.
- the well or the pipe has for example a length of the order of 1000 m, and a diameter of 160 mm.
- this tube for example steel, both ductile and able to resist corrosion of the medium to which it will be exposed; this tube, referenced 1 in Figure 2, has an outer diameter slightly smaller than that of the wall C, for example equal to 145 mm; its wall thickness is for example 4 mm. Its length corresponds to the wall length to be lined, for example about fifty meters.
- This tube is advantageously made from the surface S by fixing end-to-end and tightly tube sections, which are assembled to each other, for example by welding, then progressive depression of the tube as and when it is manufactured at inside the well or pipe, according to a well-known technique (see for example US 2 167 338).
- this tube 1 It is intended to hydroform this tube 1 by means of a crimping tool in the form of inflatable bladder, which bears the reference 2 in Figures 3 to 6.
- Such a bladder, flexible and elastic membrane is adapted to be inserted inside the tube, in the deflated state, and be positioned in a given zone of the tube that is to be expanded.
- the membrane is mounted on end caps 3a, 3b.
- distal located on the bottom side of the well
- proximal located on the other 3b, facing the surface
- the bladder is fed with high pressure liquid, able to radially expand the membrane outwards, so that it is pressed against the wall of the tube and also causes the radial expansion outwardly for the apply firmly, over a certain length, against the wall C.
- the tool is connected to the surface by a rod 4 allowing its handling, its good positioning, as well as the control members for inflating and deflating.
- a conduit for supplying and discharging the inflation liquid can be integrated into said rod 4.
- the invention begins by introducing axially into the well or pipe C a tube 1 of suitable length, facing the area to be lined. Means (not shown) for positioning, centering and axial immobilization of the tube, of a type known per se, are used for this purpose.
- the bladder 2 being deflated, it is descended coaxially inside the tube 1 (arrow J, Figure 3).
- this portion is expanded radially beyond the elastic limit of the material (in the zone of plastic deformation) so that its wall 10 is firmly and irreversibly applied against the wall internal well or pipe C, performing the anchoring of the tube at this level.
- This provides an anchoring of the distal end portion of the tube which, in addition to the action of the aforementioned immobilizing means, ensures a satisfactory retention of the tube in the longitudinal direction.
- the inflated bladder 2 is maintained and axially displaced over the entire length to be lined.
- the flexible and elastic membrane of the inflated bladder can deform slightly during operation to accommodate any profile irregularities of the conduit C.
- FIG. 7A shows a profile of duct C of variable section, comprising a zone Z whose diameter D2 is slightly greater than that D1 of the remainder of the duct.
- the bladder is then inflated by introducing a liquid under high pressure sufficient to radially expand the wall of the tube 1 beyond its elastic limit in order to apply it intimately against the wall of the duct C.
- the diameter external of the tool is ⁇ l.
- This step corresponds to the dashed representation, referenced 2 ', of the bladder in FIG. 7B.
- an anchoring zone at the base of the tube.
- the swollen bladder is then moved from the bottom upwards by traction F on the rod 4, ensuring a progressive lining of the entire length portion of the duct C to be lined which lies below the zone Z.
- FIG. 8A represents, by way of example, a lining made from a tube 6, of which three portions, referenced 61a, 61b and 61c (from bottom to top) were expanded radially and applied against the wall of the conduit C, while the intermediate portions 60a and 60b were not expanded.
- the distal lower portion 61a is first expanded by operating as indicated above, after which the bladder 2 is deflated to cross, moving from bottom to top, the portion 60a which is desired to keep the original diameter, then the bladder is inflated to expand the portion 61b, and so on.
- Figure 8B illustrates the expansion of the lower portion of the portion
- portion 61b as a result of this reinflation. Further expansion of this portion is by moving up and down the inflated bladder until it reaches the entrance to portion 60b, after which it is deflated.
- Figure 9 shows a conduit C whose section is not strictly cylindrical; it has a slightly oval shape in certain areas, which deviates from the cylindrical envelope shown in broken lines.
- this bladder automatically adapts to the possibly variable section of the latter, this of course within certain limits compatible with the deformability of the tool and with the value of the internal pressure applied to it.
- FIGS. 11 and 12 This possibility is illustrated in FIGS. 11 and 12 on which the filamentary tool has the reference 5.
- the network comprises for example two crossed plies of filaments helically wound in the opposite direction.
- Each sheet is composed of a plurality of adjacent juxtaposed filaments 7, which connect the two end pieces 3a and 3b of the tool.
- the angle ⁇ that forms a tangent to the filament with respect to the axial direction increases progressively as a result of the increase in the diameter of the winding and the relative approximation of the end pieces 3a and 3b (at the a coil spring whose turns become narrower).
- Figure 12 shows the inflated bladder, in the shape that it is desired to give it when inflated to a maximum pressure.
- the filaments of the armature are helically wound with a variable pitch.
- the deflated tool which is substantially cylindrical over its entire length.
- the angle ⁇ formed by a left-hand pitch filament section 7a or a right-hand pitch segment 7b with respect to the longitudinal axis of the tool 5 is relatively small in the central part, part which corresponds to the cylindrical portion 50 of the inflated membrane.
- the angle formed by these filament sections 7 "a and 7" b is higher, for example between 25 and 45 °.
- connection zones which correspond to the frustoconical portions 51 and 52 of the inflated membrane, the angle formed by the filament sections 7'a and 7'b is intermediate.
- This angle decreases gradually from each tip to the central area. This makes it possible to obtain an inflated bladder having a shape similar to that shown in FIG. 12.
- the angle ⁇ of winding of the filaments is naturally chosen so that the diameter of the inflated bladder is equal, and preferably slightly greater than the inside diameter of the finished liner that must be put in place.
- the taper of the portion 51 is useful for assisting the progressive expulsion of the tube during operation, as is done with a conventional rigid mandrel. This taper is maintained at a constant value when the tool is inflated to a sufficient pressure.
- the taper of the portion 52 allows a progressive connection of the cylindrical portion 50 with the tip 3a.
- the portion 51 being able for example to be in the shape of an ogive instead of a frustoconical one, and the portion 50 curved (in the form of a barrel) instead of to be cylindrical.
- the material constituting the elastic membrane is naturally chosen to withstand the high mechanical stresses during operation, in particular at its proximal zone (portion 51 in FIG. 12), which forces the wall of the tube outwards.
- this material advantageously has a low coefficient of friction allowing it to slide easily against the inner face of the tube; this sliding ability can advantageously be improved by coating the outer surface of the membrane with a lubricant, and in particular at this proximal zone. This zone, or even the entire membrane, could also be coated with an outer layer of suitable anti-friction material.
- the tool referenced 8 is provided with a shield 9 whose function is precisely to promote its sliding while protecting the surface of the inflatable membrane from mechanical aggression, in particular abrasion related to friction.
- the proximal endpiece 3b is provided at its base (tool side) with a ring 80 supporting this shield 9.
- This is composed of a set of flexible strips (semi-rigid) and flexible 90 which are fixed to the ring 80 by their upper edge. They are arranged side by side while overlapping slightly at their edges in the manner of roof tiles.
- the lamellae 90 cover the proximal zone of the tool, in which the high stresses required to dilate the tube will be exerted.
- These strips are made of a flexible material, mechanically resistant, high hardness and low coefficient of friction, metal or plastic. Their outer face is smooth.
- the tube that is expanded to make the liner is not necessarily solid wall. It may be a perforated tube, totally or partially, in certain areas, for example for the establishment of a liner acting as a filter.
- a liner of this type the implementation of which is carried out using a rigid mandrel, is known for example from US 5,366,012.
- the well or the pipe to be lined is obviously not necessarily vertical.
- the invention applies equally well to oblique, horizontal and / or non-rectilinear wells, in particular curves in whole or in part.
