Definitions
- Filtering contaminates from flowing fluids is a common exercise in systems involved in transportation of fluids. Many such systems employ screens as the filtering mechanism. Screens that expand to substantially fill an annular gap, for example, between concentric tubulars, is another common practice. Some of these systems use swaging equipment to radially expand the screen. Although such equipment serves its purpose it has limitations, including a limited amount of potential expansion, complex and costly equipment and an inability to expand to fill a nonsymmetrical space. Apparatuses that overcome these and other limitations with existing systems are therefore desirable to operators in the field.
- the expandable screen includes, a body constructed of one or more strands of a shape memory material randomly distributed in a mat structure, the body is stable at a first volume and expandable to a second volume upon a change in environment.
- the method includes, extruding one or more strands of a shape memory material, building a body having a mat structure with multiple layers of the one or more strands randomly positioned and stacked against one another, compacting the body, and cooling the body.
- FIG. 1 depicts a quarter cross sectional view of an expandable screen disclosed herein employed in a sand screen application
- FIG. 2 depicts a partial perspective view of the expandable screen of FIG. 1 shown in an alternate sand screen application.
- an embodiment of an expandable screen disclosed herein is illustrated generally at 10.
- the expandable screen 10 includes a body 14 with one or more strands 18 of a shape memory material 22 distributed in a mat structure 26.
- the body 14 is stable at a first volume (as illustrated in Figure 1) and is expandable to a second volume that is greater than the first volume. Changes in the environment of the body 14 drive the change from the first volume to the second volume. In this embodiment, the change in environment is an increase in temperature. Other effective changes may be surrounding fluid, magnetic field, or the like.
- the body 14 illustrated in this embodiment is formed by extruding the strands 18 of the shape memory material 22 and building the mat structure 26 layer 30 by layer 30 with random positioning of each new strand 18 over the strands 18 already positioned.
- layer 30 is used loosely to explain that each new strand 18 is applied over older strands 18 and not to imply that each layer 30 is actually separated and definable relative to each other of the layers 30.
- the strands 18 are at an elevated temperature while extruding resulting in at least entanglement and possibly intermittent bonding of the strands 18 to one another wherever they happen to be in contact during the extruding and mat forming process.
- the mat structured body 14, upon completion of the manufacturing process, is in the second volume configuration.
- the body 14 can then be compacted to the configuration of the first volume where it is cooled thereby forming the body 14 into a stable first volume configuration.
- the stability of the body 14 in the first volume can be maintained until the body 14 is heated to a temperature wherein the shape memory material changes shape, at which time the body 14 will begin changing toward the second volume.
- FIG. 1 the embodiment of the expandable screen 10, as illustrated, is employed in a sand screen 36 application for a downhole hydrocarbon recovery application.
- the body 14 has a cylindrical shape and is positioned radially outwardly of a base pipe 34 that has holes 38 therethrough and illustrated herein as a perforated tubular.
- the body 14 and the base pipe 34 are assembled and positioned within a borehole 42 in an earth formation 46.
- the body 14, as illustrated in the Figure, is in the first position, which is also known as the run in position, wherein an outer surface 50 of the body 14 is dimensioned radially smaller than a radial dimension of an inner surface 54 of the borehole 42.
- the body 14 can be heated to a temperature wherein the shape memory material changes shape, thereby expanding the body 14 towards the second volume.
- the body 14 may not reach the second volume since contact with the inner surface 54 may prevent the volumetric expansion of the body 14 from continuing. Such contact is desirable since it maintains the structure of the formation 46 and minimizes erosion thereof, while allowing fluid to flow through the formation 46 and be filtered by the screen 10 before flowing through the holes 38 and into the inside 58 of the base pipe 34.
- the shape memory material 22, as illustrated in this embodiment, may be a metal such as Nitinol, which is an equiatomic alloy of nickel and titanium that has the symbol NiTi, while in other embodiments the shape memory material 22 may be nonmetallic, such a polymeric, for example.
- NiTi shape memory metal alloy can exist in two different temperature-dependent crystal structures (phases) called martensite (lower temperature) and austenite (higher temperature or parent phase). Several properties of austenite NiTi and martensite NiTi are notably different. When martensite NiTi is heated, it begins to change into austenite. The temperature at which this phenomenon starts is called austenite start temperature (A s ).
- austenite finish temperature A f
- austenite NiTi When austenite NiTi is cooled, it begins to change into martensite.
- martensite start temperature M s
- martensite finish temperature M f
- the body 14 in the first volume, as formed in this embodiment, is in the austenitic form. It is then deformed to the new second volume at a temperature under M f .
- the body 14 in this second volume is dimensioned to have clearance relative to the inner surface 54 for running into the borehole 42. The temperature is then raised above the transition temperature (A s ), and the body begins to expand towards the second volume.
- Filtration characteristics of the screen 10 will depend upon several factors. For example, the dimensions of the strands 18, the complexity of the mat structure 26 and the amount of compaction as deployed. The dimensions of the strands 18 and the complexity of the mat structure 26 are both controllable in the manufacturing process. Additionally, the amount of compaction as deployed can be estimated based on knowledge of the dimensions of the inner surface 54 relative to the dimensions of the base pipe 34 and the body 14 positioned thereon when in the first volume configuration. [0014] Referring to Figure 2, an alternate embodiment of a sand screen disclosed herein is illustrated at 60.
- the sand screen 60 allows for additional control over final filtration properties in comparison to that of the sand screen 36 by positioning the body 14 concentrically radially outwardly of a separate filter component 62. As such, by setting the filtration properties of the filter component 62 finer than those of the body 14 the final filtration properties are established based primarily upon those of the filter component 62. Additionally the filter component 62 could be made of a material that does not expand, thereby avoiding changes in filtration properties that result from expansion had the filter component 62 been configured to expand.
