Abstract
An apparatus for controlling sand production within a wellbore completed to a subterranean reservoir is disclosed. The apparatus will include a base supporting member that has a series of perforations included thereon. A jacket member is disposed about the base supporting member, with the jacket member being a helical member with overlapping loops forming multiple passages for the flow of a subterranean gas and fluid. A protective member disposed about the jacket may also be included, with the protective member having a series of perforations formed thereon.
Claims29
An apparatus for controlling sand production within a wellbore completed to a subterranean reservoir comprising:
- a first supporting member formed with a series of perforations thereon, said supporting member having a first end and a second end;
- a screen mounted over said first supporting member;
- a jacket member mounted over said screen presenting exterior and interior surfaces and defining at least one opening extending from the exterior to the Interior surface through the jacket member for presenting first, second and third passageway portions, with the first passageway portion extending generally radially outwardly from the exterior surface, with second passageway portion extending generally along the direction of the interior surface and generally perpendicular to the first passageway portion, and with the third passageway portion extending generally radially Inwardly from the interior surface and generally perpendicular to the second passageway, with the first passageway portion being spaced from the third;
- wherein production fluid from the reservoir approaches said jacket member and is directed into the first passageway generally radially, then changes direction and flows in the direction of the Interior surface of said jacket member, and then changes direction again and flows away from the Interior surface radially and directly toward said screen.
The apparatus of claim i wherein said first end and second end of said first supporting member have contained thereon thread means for threadedly attaching a mating thread to said first supporting means, and wherein said jacket member is attached at the first end and the second end of said first supporting member, the apparatus further comprising:
- a second supporting member, with said second supporting member having a first end and a second end, with said first and second end containing thread means for threadedly attaching to said first supporting member so that said first supporting member and said second member are interconnected in tandem relationship;
- and,
- a second jacket member disposed about said second supporting member, and wherein said second jacket member is attached to said second supporting member at the first end and second end, respectively, of said second supporting member.
An apparatus positioned within a wellbore for controlling said production comprising:
- a supporting member with an inner and outer portion, said supporting member having a series of apertures formed thereon;
- a first member helically wrapped about said supporting member;
- and wherein said helical wrapped member about said supporting member forms a continuous flow passage into the inner portion of said supporting member, with the continuous flow passage comprising a first, second and third segment between wraps of the wrapped member with the passage being offset from one passage to the next for the flow of a subterranean fluid and gas into said inner portion of said supporting member;
- said second segment of said passage being at an angle to said first segment to present a circuitous passage that changes the direction of flow at least once.
An apparatus for controlling the sand production from a subterranean wellbore, the wellbore intersecting a subterranean reservoir containing hydrocarbons, said apparatus comprising:
- a base conduit having a series of ports to allow the flow of subterranean gas and fluids;
- a jacket member disposed about said base conduit, said jacket member having a wound helical member with overlapping loops, and with said helical member being contoured such that the overlapping loops form a first, second and third passage for the flow of subterranean gas and fluids, said first passage allows flow to radially approach said jacket member, said second passage constitutes a continuation of said first passage, and is generally axially oriented through said jacket member, said third passage allows flow to directly approach said base conduit;
- screen means, arranged about said jacket member, for preventing the flow of sand from the subterranean formation into the inner diameter of said base pipe.
An apparatus for completing a wellbore comprising:
- a cylindrical member extending into the wellbore, said cylindrical member having an inner and outer diameter;
- packer means, operatively associated with said cylindrical member, for sealingly engaging the wellbore;
- a cross-over tool means, connected to said packer means, for placing a gravel slurry in the annulus of the wellbore;
- screen means, connected to said tubing string, for preventing the flow of sand into the inner diameter of said cylindrical member and allowing passage of a subterranean fluid and gas, with said screen means comprising:
- a base conduit formed with a series of perforations thereon, said base conduit having a first end and a second end;
- a contractible jacket member disposed about said base conduit, said contractible jacket member having a continuously wound helical member with overlapping loops, and with said helical member being contoured such that the overlapping loops form a first, second and third passage between wraps of the wrapped wire member with the passage being offset from one passage to the next for the flow of the subterranean fluids and gas, said first passage allows flow to radially approach said jacket member, said second passage constitutes a continuation of said first passage and is generally axially oriented through said jacket member, said third passage allows flow to directly approach said base conduit;
- and wherein said contractible jacket member is attached to said base conduit at the first end and the second end.
An apparatus for controlling sand production within a wellbore completed to a subterranean reservoir comprising:
- a supporting member formed with a series of perforations thereon, said supporting member having a first end and a second end;
- screen means, disposed about said supporting member, for preventing the flow of sand from the subterranean formation into the inner diameter of said supporting member;
- and,
- a jacket member disposed about said screen means, said jacket member comprising a wound member with overlapping loops, and with said wound member being contoured such that said overlapping loops form no more than a first and second passage for the flow of a subterranean gas and fluid;
- wherein production from the reservoir approaches said jacket and is directed into said first passage which is generally axially aligned with said jacket member and flow continues toward said supporting member as said second passage forms an offset which directs flow directly at said supporting member.
