Definitions
- the present invention relates to a tubular preform or matrix structure for casing a well, in particular an oil well.
- casing means a tube for consolidating a well
- preform a tubular structure which is initially flexible and is then hardened to bind intimately and to remains against the wall of a well (thus constituting a casing)
- matrix a flexible and recoverable structure serving as a tool for expanding the preform and applying it against the wall of the well before it hardens.
- production tubing refers to a tube coaxial with a casing, and of smaller diameter, making it possible to convey the fluid produced by the well (water or oil in particular).
- the preform has, after radial deployment, a strictly cylindrical shape, of well-defined diameter.
- the wall of the preform is hardened, for example by polymerization of this wall which has a composite structure composed of a resin impregnating with parliamentary sleeves.
- the objective of the present invention is to solve this problem by proposing a preform whose structure has a deformable geometry capable of being applied to the walls of the hole to be tubed (or casing to be lined) without, however exceed certain limits, this deformation being controlled and variable depending on the different applications.
- Another object of the invention is to provide a preform whose degree of expansion is significantly higher than those obtained with known devices of the aforementioned kind, the expansion of the preform being carried out in two stages, first by deployment radial, then by radial expansion.
- the invention provides a braided tubular structure, which will be described later, this structure can also be applied to a radially expandable matrix, that is to say a removable (and reusable) tool serving to the expansion of a preform with a view to casing a well, whether or not this preform has the structure according to the invention.
- this braiding comprises two series of wicks symmetrically intersecting on either side of the generatrices of the tubular structure, that is to say with respect to its longitudinal axis, the wicks of each series being parallel to each other.
- each of the series of wicks forms an acute angle with the longitudinal axis which is between 10 ° and 30 °, and is preferably of the order of 20 °, when the structure is in its radially contracted state, while this angle is between 50 ° and 70 ° when the structure is in its radially expanded state.
- the locks are flat, affecting the shape of ribbons.
- the tubular preform which is also the subject of the invention, is remarkable in that it has a structure as described above.
- the preform has a wall made of composite material, formed of a fluid and hardenable medium in which said structure is embedded, this medium being confined between inner and outer skins made of elastic material.
- the inner skin could be the very wall of the matrix.
- this material is a hardenable resin, for example heat-curable.
- the outer skin has reliefs, for example in the form of annular bulges.
- the structure comprises several elementary coaxial tubular structures which are in accordance with the invention, these different tubular structures being fitted into one another with the possibility of relative sliding.
- the structure is flexible enough to be able to be folded in on itself longitudinally when the structure is in its radially contracted state.
- the invention also relates to a tubular matrix with a flexible and radially expandable wall, intended to be applied Radially against the inner wall of a preform before and during hardening thereof, in order to produce the casing of a well, and in particular of an oil well.
- the wall of the matrix is provided with at least one tubular structure linked to an elastic support (also tubular, and waterproof) and comprising a braiding of flexible wicks composed of fibers, which intersect with a certain play, so that this structure and its support can expand jointly in the radial direction, while being restricted in the axial direction, under the effect of an internal pressure, while conversely, they can shrink radially while lengthening axially under the effect internal vacuum (vacuum) and / or axial traction.
- an elastic support also tubular, and waterproof
- a braiding of flexible wicks composed of fibers which intersect with a certain play
- the tubular structure is inserted between two elastic membranes, one inside and the other outside, the assembly forming an inflatable sleeve equipped with a tube supply of fluid in the sleeve.
- such a matrix is fixed to the preform by means of easily breakable connecting elements, making it possible to tear off the matrix after the casing operation, leaving the latter inside the tube or the pipeline.
- FIGS 1, 2, 3 are diagrams showing a preform or a matrix provided with a tubular structure according to the invention, this preform or matrix being represented respectively in the radially contracted state, in an intermediate state and in a radially expanded state;
- Figures 1A, 2A and 3A are detailed views showing the braiding of flexible wicks constituting the structure, in a deformation state corresponding to Figures 1, 2 and 3 respectively;
- the figure is a perspective view with cutaway of a preform according to the invention having several structures fitted into each other;
- Figure 5 is a cross section, on a larger scale, of the preform of Figure k;
- FIGS. 6A and 6B are schematic views of the section of the preform axially folded back on itself, in two different possible configurations;
- Figures 7 and 7 are similar views of one or the other of the preforms of Figures 6A or 6B, respectively after deployment and after radial expansion;
- Figure 8 is a view similar to that of Figure 2A showing a variant of the structure braiding mode
- FIG. 9 is a schematic view in longitudinal section, of a matrix and a preform both according to the invention, during the establishment of the preform in a well, matrix and preform being deployed, but not radially expanded;
- Figure 9A is a detail on a larger scale of the area of the wall of the matrix and the preform which is referenced A in Figure 9;
- FIGS 10, 10A, 10B, 10C and 10D are schematic views intended to illustrate the different successive stages of the installation of casing in an oil well by means of production tubing, help of the matrix - preform assembly of figure 9.
- FIGS. 1 to 3 show the progressive inflation of a matrix during the expansion of a preform in a well.
- the preform or the matrix designated 1 in FIGS. 1 to 3 has a tubular shape provided with a braided structure. This is made up of an intertwining of two series of flat wicks, or ribbons 10a, 10b which are wound in a helix to form the envelope of the structure.
- the two series are of opposite pitch, and the wicks are inclined at an acute angle u_ relative to the generator of the tube which it forms, which is cylindrical.
- the axis XX ′ of the tube has been taken as a reference in FIGS. 1 to 3.
- the two series of wicks 10a and 10b are intertwined like a cane, symmetrically with respect to the axis XX ', on either side of the latter.
- the angle u_ is of the order of 20 ° ( Figures 1 and 1A).
- Each of the locks 10 is formed from a plurality of fibers or threads having high mechanical strength, and inextensible, joined to each other. These are, for example, glass or carbon fibers having a diameter of a few micrometers, or steel wires.
- the wicks 10 have a width of between 1 and 6 mm, and a thickness of between 0.1 and 0.5 mm.
- the material constituting the fibers or threads which form these locks have a low coefficient of friction, promoting the mutual sliding of the interlaced locks, and consequently promoting the deformability of the structure.
- the braiding of the two series of wicks 10a on the one hand and 10b on the other hand is done with a certain play, giving a loose assembly which spares spaces 1 1 in the form of diamonds at the 'intersection of the two series 10a, 10b.
- Figure 1 there is shown the preform or the matrix in the configuration which gives it the greatest possible length L1.
- L1 the structure is self-locked, the different wicks being supported by their edges against each other.
- the preform has a minimum diameter Dl.
- the braiding is determined so that this blocking takes place when the angle w formed by the locks relative to the axial direction of between 50 ° and 70 °.
- the structure then has a minimum length L3 and a maximum diameter D3.
- the braiding shown in Figures 1A to 3A is a braiding simple, in which a wick 10a passes alternately above and below a wick 10b, and vice versa. It goes without saying that other braiding modes can be envisaged, such as for example that shown in FIG. 8. According to the latter, each wick 10a passes successively above and below two wicks 10b, and reciprocally only.
- FIG. 1 shows a preform 1 capable of industrial application.
- This comprises several deformable tubular structures such as that which has just been described, in this case four structures 3a, 3b, 3c and 3d coaxial, and of increasingly smaller diameters, fitted into each other.
- a higher number for example of ten fitted structures can naturally be provided. They are confined between two skins of elastic materials, for example of elastomeric material, one exterior and the other interior. The role of the latter could be played by the wall of the matrix. They are impregnated with a fluid but curable medium, for example a resin thermosetting polymerizable hot, housed between the two skins and 5.
- the deformation ability of the skins and 5 is chosen to be compatible with that of the braided structures 3, the deformation of the assembly being done jointly, and with the same amplitudes.
- FIGS. 6A and 6B show two possible (non-limiting) modes of folding, respectively in the shape of a U and in the shape of a snail (spiral). Following such folding, it is therefore possible to give the preform a cross section having a very small footprint.
- the preform By unfolding, the preform can be deployed, to give it the cylindrical shape shown in FIG. 7. Then, for example by applying an internal overpressure, it is possible to cause the radial expansion of the preform, by deformation of each of the concentric structures 3a , 3b, 3c and 3d by applying the phenomenon described above.
- FIG. 9 represents a preform similar to that which has just been described associated with a dilator tool intended to ensure its positioning in a well, a tool hereinafter called a matrix.
- the preform 1, shown in the unfolded state, but not expanded, comprises - as already said - a medium 30 of thermosetting resin which occupies the annular space located between two skins of elastic material one external and the other internal 5 or 71 (from sleeve 7). In this space there are also several deformable tubular and concentric structures formed by braided ribbons 3.
- the matrix - referenced 6 - comprises a tubular sleeve 7 closed at its upper and lower ends by plugs 60 respectively 61.
- the upper plug 60 is crossed by a tube 8 which has openings 80 opening, just like its free end, at inside the sleeve 7.
- Appropriate means, not shown, make it possible to introduce a pressurized liquid through the tube 8 inside the sleeve 7, via a flexible conduit. This liquid can be brought in from the surface.
- the wall of the sleeve consists of two elastic menbranes, for example of elastomeric material, one inside 72 and the other outside 71. Between the two membranes is a tubular structure with braided wicks as described above, referenced 70. In alternatively, several concentric structures can be provided, fitted into one another as is the case for the preform.
- the length of the sleeve 7 is greater than that of the preform 1. End plugs 60, 61 are fixed, for example by gluing, in the end zones of the inner membrane 72.
- the sleeve 7 is fixed, by its external membrane 71, to the preform 1, by means of end sleeves 73, 74. These have rupture zones 730, respectively 740.
- the sleeves 73 and 74 form seals sealing between the preform and the sleeve 7 constituting the matrix 6.
- the interface between the outer membrane 71 of the sleeve and the inner skin 5 of the preform is treated, for example by coating with silicone, so that there is little adhesion between these two elements.
- the inner skin can be removed.
- the outer face of the outer skin of the preform has pads 40. These are for example annular bulges separated by also annular cavities 41. The function of these pads is to promote sealing with the wall of the well, and to retain a prestress and a certain flexibility after hardening.
- FIG. 10 and the following ones illustrate the casing operation of an oil wellbore through a production tubing by means of the preform 1 and using the matrix which have just been described.
- the well wall and the reference 9 designate the production tubing equipping the well, this tubing being retained and centered by a hydraulic shutter - or "packer" - 90.
- the inside diameter of tubing 9 is 60 mm while the average diameter of the well is of the order of 180 mm.
- the preform is introduced by being folded back on itself, for example in a snail (see FIG. 6B) in such a way that the largest dimension of its cross section is less than the inside diameter of the tubing 9.
- This larger dimension is for example of the order of 55 mm.
- the preform is therefore lowered, at the same time as the tube 8, to the desired level inside the well. Initially, we will cause the deployment of the preform 1, making it take a cylindrical shape.
- the degree of expansion is done as needed, that is to say according to the roughness of the wall. This is an essential difference compared to the known flexible preform device, the radial expansion of which can only take place according to a well-defined diameter.
- the preform therefore adapts to the configuration of wells it encounters. This is further favored by the presence of the pads 40, which provide anchoring and sealing.
- the wall of the preform is then allowed to harden, by introducing and circulating a hot fluid (and under pressure) in the sleeve 7.
- a hot fluid and under pressure
- the sleeve 7 lengthens by retracting radially, and it is possible to extract it through the tube 9.
- the old preform 1, hardened, constitutes a casing element of the well.
- Such tubing can be used with or without cement, depending on the soil conditions encountered.
- the reference 7a designates the portion of the matrix already constricted, and detached from the casing, whose strands of structure form the angle u_.
- the reference 7b designates the expanded portion, the wicks of which form the angle.
- FIGS. 12 and 12A there is shown an expansion of the matrix 7 and of the preform 1 which takes place gradually, from the bottom to the top, an inflation liquid being introduced, via the conduit 8, to the lower part of the matrix.
- the inflation progression can be obtained for example by enclosing the preform and the matrix (in the folded state) in an envelope capable of tearing longitudinally and from bottom to top.
- the braided deformable structure in accordance with the invention can be implemented with preforms, the installation of which would not require inflation dies using such a structure, and vice versa.
- certain fibers of at least some of the wicks (and, advantageously of all the wicks) are replaced by electrically conducting wires, allowing the preform or the heating to be heated. matrix, for the polymerization of the matrix, when connected to a power source.
