A sand screen cartridge including a plurality of longitudinally extending segments together forming a tubular filtration media. An end ring engaging the filtration media.
Latest BAKER HUGHES INCORPORATED Patents:
In the drilling and completion industry, the formation of boreholes for the purpose of recovering hydrocarbons necessarily is accompanied by sand. Sand control therefore is a significant concern for operators and must be addressed in the downhole environment prior to its production with target fluids. This is because flowing sand is damaging to production equipment from the standpoint of erosion and further because it can adversely affect other equipment such as pumps, etc. Also notable is that the production of sand from the formation in which a borehole exists will tend to enlarge the borehole and increase the probability of cave ins, wash outs, etc., that would require remedial activity at not insignificant cost both in actual dollars and in lost production time.
The art is therefore very concerned with sand control and has developed a plethora of types of sand screen and such to mitigate the problem. In view of ever changing conditions and techniques however, the art is always in need of and receptive to alternative arrangements.

The use of the terms “a” and “an” and “the” and similar referents in the context of describing the invention (especially in the context of the following claims) are to be construed to cover both the singular and the plural, unless otherwise indicated herein or clearly contradicted by context. Further, it should be noted that the terms “first,” “second,” and the like herein do not denote any order, quantity, or importance, but rather are used to distinguish one element from another. The modifier “about” used in connection with a quantity is inclusive of the stated value and has the meaning dictated by the context (e.g., it includes the degree of error associated with measurement of the particular quantity).
The teachings of the present disclosure may be used in a variety of well operations. These operations may involve using one or more treatment agents to treat a formation, the fluids resident in a formation, a wellbore, and/or equipment in the wellbore, such as production tubing. The treatment agents may be in the form of liquids, gases, solids, semi-solids, and mixtures thereof. Illustrative treatment agents include, but are not limited to, fracturing fluids, acids, steam, water, brine, anti-corrosion agents, cement, permeability modifiers, drilling muds, emulsifiers, demulsifiers, tracers, flow improvers etc. Illustrative well operations include, but are not limited to, hydraulic fracturing, stimulation, tracer injection, cleaning, acidizing, steam injection, water flooding, cementing, etc.
While the invention has been described with reference to an exemplary embodiment or embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiment disclosed as the best mode contemplated for carrying out this invention, but that the invention will include all embodiments falling within the scope of the claims. Also, in the drawings and the description, there have been disclosed exemplary embodiments of the invention and, although specific terms may have been employed, they are unless otherwise stated used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention therefore not being so limited.
Claims
1. A sand screen cartridge comprising:
- a plurality of longitudinally extending segments together forming a tubular filtration media;
- an end ring engaging the filtration media.
2. A sand screen cartridge as claimed in claim 1 wherein the plurality of segments include offsets to space certain sides of the plurality of elements from mating sides of the plurality of elements to create radial fluid passageways through the filtration media.
3. A sand screen cartridge as claimed in claim 1 wherein the plurality of segments further include standoffs to space the segments from a base pipe when installed thereon.
3. A sand screen cartridge as claimed in claim 1 wherein the plurality of segments are staves.
4. A sand screen cartridge as claimed in claim 3 wherein the segments are about 6 to 15 inches long.
5. A sand screen cartridge as claimed in claim 1 wherein the segments comprise a ceramic material.
6. A sand screen cartridge as claimed in claim 1 wherein the segments comprise a core of one material and an exterior of another material.
7. A sand screen cartridge as claimed in claim 1 wherein a filtration area of the sand screen is proportional to the number of segments and the length of the segments.
8. A sand screen cartridge as claimed in claim 1 wherein each segment is one of trapezoidal or curved trapezoidal cross section.
9. A sand screen cartridge as claimed in claim 1 wherein the end ring contacts inner and outer surfaces of the filtration media near a longitudinal end of the filtration media.
10. A sand screen cartridge as claimed in claim 9 wherein the end ring is a resilient material.
11. A sand screen cartridge as claimed in claim 9 further comprising a reinforcer located at a portion of the end ring that contacts either or both of the inner and outer surfaces of the filtration media.
12. A sand screen cartridge as claimed in claim 1 wherein the plurality of segments comprise a highly erosion resistant material.
13. A sand screen cartridge as claimed in claim 1 further comprising a shroud disposed radially outwardly of the filtration media.
14. A sand screen cartridge as claimed in claim 1 wherein the end ring comprises two openings to receive filtration media.
15. A sand screen cartridge as claimed in claim 14 wherein the end ring comprises one opening to receive filtration media.
16. A sand screen cartridge as claimed in claim 15 wherein the ceramic comprises Sintered Boron Carbide, Silicon Carbide and/or Alumina.
17. A sand screen comprising:
- a base pipe;
- a plurality of longitudinally extending segments together forming a tubular filtration media about the base pipe;
- an end ring engaging the filtration media and the base pipe.
18. A sand screen as claimed in claim 17 further comprising a shroud disposed radially outwardly of the filtration media.
19. A sand screen as claimed in claim 18 wherein the shroud is welded to a backup.
20. A sand screen as claimed in claim 18 wherein the shroud is welded to the basepipe.
