Priority information
The application is the part continuation application of the U.S. Patent application 10/226,941 of submission on August 23rd, 2002.
Technical field
Technical field of the present invention is a well screen, can expand with the well screen of the irregularly shaped well of packing in open hole well more specifically.
Background technology
In the past, anti-sand method has been dominated in the gravel pack of well screen outside.Its thought is to fill the outer annular space of screen casing to prevent the undesired solid of output from the stratum with sand.Recently, along with the appearance of tubular expansion technology, by annular space around the sandfilling, just do not needed gravel pack before having eliminated if expected screen casing to expand on the spot.Because the pit shaft out-of-shape has just occurred problem to screen expansion technique as substituting of gravel pack.Fixing tube expander is the fixing quantity of screen expansion.Problem is that the erosion in the pit shaft still can stay big annular space in the screen casing outside.On the contrary, the undergauge place in the pit shaft will produce the risk of blocked portion fixed swage.
An improvement of fixed swage technique is to use various forms of flexible tube expanders.In theory, these flexible tube expanders have compliance, therefore at the undergauge place they with turning-in, thereby reduced the risk of blocked portion tube expander.On the other hand, if free zone, same problem exists, and the external dimensions of the outside expandable screen of energy that promptly flexible tube expander had is limited.Therefore, when using flexible tube expander, still exist the screen casing outside to leave the problem of annular clearance, like this when well when this zone produces, will cause the output of undesired solid.
The precommpression felt that is kept by protective metal shell has been used in screen casing design in the past, and when being placed into the position of down-hole expectation, protective metal shell suffers chemical attack so.Felt just can expand from its pre-compressed state then.Screen casing does not expand.This design is at United States Patent (USP) 2,981, is described in 332 and 2,981,333.Patent 5,667,011 discloses the fixed swage that the down-hole slotted liner is expanded.United States Patent (USP) 5,901,789 and United States Patent (USP) 6,012,522 well screen that is inflated is disclosed.United States Patent (USP) 6,253,850 disclose an atresia bushing pipe have been inserted in another slotted liner that has expanded with its technology of packing, and use rubber or epoxy resin to seal between bushing pipe.United States Patent (USP) 6,263,966 disclose the screen casing with vertical pleat in expanded downhole.United States Patent (USP) 5,833,001 discloses rubber solidifies on the spot to make sticking patch after being expanded by dilatant.At last, United States Patent (USP) 4,262,744 relate generally to the technology of utilizing mould to make screen casing.
Apparatus and method of the present invention have the outer field screen assembly that can adapt to wellbore shape after the expansion and solve this problem by providing.In a preferred embodiment, dilatable material when the material of selection is the contact wellbore fluids is further to promote zone empty in the filling well after expansion.In design as an alternative, do not need screen expansion, outermost layer touches and expands to adapt to the shape of well after wellbore fluids or other are introduced the fluid of pit shaft.Sieve tube segment is to make in the mode that reduces or eliminates weld seam.Weld seam can be in expansion process under the violent load, therefore make weld seam minimum or eliminate weld seam provide expand after screen operation more reliably.These and other advantage of the present invention to those skilled in the art can be more obvious after description of having read the back preferred embodiment and claim.
Summary of the invention
Screen assembly has the material that can adapt to wellbore shape after the insertion.This assembly comprises the adaptation layer that has wellbore shape after the expansion.Skin is formed has the hole to allow flowing of output object.Selected material is expanded by heating preferably, and preferably includes the thermoset shape memory foamed material.Can have screen casing on the parent tube, to be used as the substrate layer that supports adaptation layer or selectively be used for sieving.Adaptation layer can self expand and maybe can expand in parent tube.
Description of drawings
Accompanying drawing 1 is the screen casing facade view; With
Accompanying drawing 2 is the sectional views that are in the screen assembly of expanded downhole position, and one of them screen casing has been presented in the accompanying drawing 1.
The specific embodiment
Accompanying drawing 1 has shown the part of one section screen casing 10.It has parent tube 12, is screen casing 14 on it, is outside adaptation layer 16 above the screen casing 14.Layer 16 has a plurality of holes 18.Parent tube 12 also has hole 20.Actual filtering material or screen casing 14 can be silk screen or fabric or other known filtering product.Adaptation layer 16 is preferably soft, and it will flow when expanding with convenient screen casing 10.Preferable material is a dilatable material after the time that is exposed to wellbore fluids one elongated segment.Three examples are nitrile, natural rubber and AFLAS.In embodiment as an alternative, adaptation layer 16 fully expands with the contact pit shaft after putting into pit shaft, and screen casing 10 does not expand.What schematically show in screen casing 10 ends 22 and 24 is locating snap ring 26 and 28.When screen casing 10 expands, these locating snap rings will limit adaptation layer 16, in case adaptation layer 16 is vertically moving in the annular space of screen casing 10 outsides after the screen expansion.Their use is selectable.
The assembling mode of screen casing 10 is another aspect of the present invention.Adaptation layer 16 can have and allows it to be set to internal diameter on the screen material 14.The assembly of screen material 14 and adaptation layer 16 is set on the parent tube 12.Afterwards, apply known bloat tool, so that its slight expansion in parent tube 12 inside.As a result, screen material 14 and adaptation layer 16 all are fixed on the parent tube 12, and need not welding.This is favourable, because when screen casing 10 is lowered in the pit shaft and is inflated, expansion process can apply big stress by butt welded seam, and this can cause screen casing to lose efficacy.A kind of selection mode of assembling screen casing 10 is according to the mode of just having described screen material 14 to be attached on the parent tube 12, then solidifies adaptation layer 16 on screen material 14.Another selection is, can apply protectiveness overcoat (not shown) on screen material 14, puts adaptation layer 16 is installed outside protectiveness.Even adopt selectable perforation protection overcoat (not shown), connecting technology also is outwards to expand in parent tube 12 as previously described.
Hole 18 can be a different shape.Their function is to allow formation fluid to flow through after expansion.They can be circular ports, perhaps slit, perhaps other shape, the perhaps combination of shape.Adaptation layer 16 can be made by polymeric material, the material that preferably when continuing to be exposed to wellbore fluids, expands, and irregularly shaped with better adaptation well 30, as shown in Figure 2.Accompanying drawing 2 also shown be placed on the screen material 14, the outer protection overcoat 32 under the adaptation layer 16, with protection screen material 14 when putting into well 30.Overcoat 32 is the known product with opening 33 of going out, and if used adaptation layer 16, can optionally use overcoat 32.It is that selectable reason is, adaptation layer 16 provides desired protection to a certain extent in being lowered to process.In addition, do not have overcoat 32, adaptation layer 16 can be made thicklyer, with the voidage 34 in the annular space around the filling screen casing 10 better after expansion.The thickness of adaptation layer 16 is limited by well and the external diameter that is installed in its inner member.Preferably, adaptation layer 16 is pushed tightly, because promote it to move with the space in the annular space around filling like this.
It will be appreciated by those of skill in the art that the present invention allows the manufacturing of inflatable screen casing to eliminate weld seam between the layer.The use of adaptation material 16 allows to use multiple expansion technique, and has improved the ability of eliminating the expandable screen external void that causes owing to hole anomaly.Alternatively, screen casing 10 not under the situation of expanded downhole adaptation material 16 can fully expand, to allow to eliminate the necessity of gravel pack.If this material expands owing to being exposed to downhole fluid, expect used as adaptation layer 16.Protective sleeve 32 below the adaptation layer 16 can be used for being lowered to process protection screen material 14.
Adaptation layer 16 can be a foamed material, is preferably the thermosetting foams material, but also can be thermoplastic foam.Shown adaptation layer 16 is cylindric, but can change, and for example by recessed end or streaky regional (not shown), is beneficial to arrange, perhaps strengthens the filtering feature of this layer.Adaptation layer 16 preferably is made of the elastic memory foamed material, for example the perforate composite foam material.This foamed material has the character that can change another kind of size and/or shape by changing foam temperature from a kind of size and dimension into.This foamed material can form the object with required original size and shape, for example has the cylinder of required external diameter.The foams of Xing Chenging then are heated like this, so that its temperature is elevated to its transition temperature.When it reached transition temperature, foamed material was softening, allowed foams to be configured as the transition size and dimension of expectation again, for example passed through compression to form the cylinder than minor diameter.The temperature of foams then is lowered to below the transition temperature, so that foams keep its transition size and dimension.When being elevated to its transition temperature again subsequently, foams will recover its original size and shape.
Cylindrical foam adaptation layer 16 can have the original outer diameter OD of expectation by winding 1Foam carpet and initially be formed on screen casing 10 or the parent tube 12.Alternatively, the technology that forms adaptation layer 16 on parent tube 12 or screen casing 10 can be any other technology that produces the adaptation layer 16 with expectation green diameter, for example molded foam body directly.The original outer diameter OD of expectation 1Than the borehole diameter (BHD) of arrangement is big.For example, have 10 inches original outer diameter OD 1Adaptation layer 16 can be formed the well that is used for 8.5 inch diameters.
Foam material composition is prepared, to realize the transition temperature of expectation.This character makes and can prepare foamed material under the situation of the expectation transition temperature of estimating to be used for application-specific.For example, be used for when of the present invention, foam material composition can be prepared, so that transition temperature is only a little less than the expectation downhole temperature of assembly with the degree of depth place that is used.This causes the temperature expansion of adaptation layer 16 at this desired depth place, and keeps being inflated on the well bore wall.Downhole temperature can be used to the adaptation layer 16 that expands; Alternatively, can make otherwise for example independent thermal source.Such thermal source can be the electric heater of wireline deployed, or battery powered heater.For example, such thermal source can be installed on the parent tube 12, be incorporated in it or be mounted to foam adaptation layer 16 and contact.Heater can be from the well site Ground Control, perhaps by timing means or pressure sensor control.Also have, can produce exothermic reaction, perhaps can produce heat by other any suitable manner by the chemical substance that pumps into to the down-hole from ground.
Adaptation layer 16 can be made as unique filtering medium, and does not use any screen material, and for example 14.This is because the character of adaptation material is mushy.But its conventional production technology is that mould stays non-permeable formation in its whole peripheries.This character allows this material can be used as packer material basically under the condition of the demoulding.But if finally the non-permeable formation of the external surface that contacts with well bore wall is stripped from or otherwise is removed, adaptation layer 16 can be installed on parent tube 12 or the screen casing 14, and can use as unique filtering material or with screen casing 14 separately.Screen casing 14 can be configured to be specifically designed to the support structure of adaptation material 16, makes adaptation material can not pass parent tube 12 to see through when wellbore fluids when adaptation material 16 is filtered, and perhaps screen casing can be saved fully.The aboveground end of adaptation material 16 and downhole end can have the non-permeable formation that molding process stays when making, better fluid is directed to opening in the parent tube 12.
Adaptation material is shape-memory polymer preferably, and this polymer is mushy and heat cured, although also can adopt thermoplastic, if thermoplastic is mushy, perhaps can make under the sort of condition.
Disclosure and description above the present invention are exemplary with indicative, can carry out various variations on the detail of size, shape and material and example structure, and not depart from essence of the present invention.
