The specific embodiment
Referring to Fig. 1 and Fig. 2, wherein show the well screen 1 that is arranged in the pit shaft 2 of producing hydrocarbon fluid.Screen casing 1 comprises: tubular part 3; With the permeable annular outer layer 4 of radial distance around tubular part 3, the described outer 4 covering layer 4b by the filtration beds 4a and the filtration beds outside constitute; And be arranged between tubular part 3 and outer 4 to encircle the inflatable element that 6 form exists.Ring 6 is along the spacing setting of tubular part 3 with rule.Thereby outer 4 are flexible and can at least one expansion rate expanded radially make the covering layer 4b contact borehole wall.In addition, filtration beds 4a has and is suitable for preventing that solid particle from flowing into the screen size in the tubular part.Ring 6 is made by the elastomeric material that expands when contacting hydrocarbon fluid, and described elastomeric material for example is an EPDM rubber.Tubular part 3 has the eyelet 7 that a plurality of hydrocarbon fluids that are used to make output flow into tubular part 3, and has at its end and to be used to make well screen 1 to be interconnected to conduit 9 is transported to ground with the hydrocarbon fluid with output corresponding coupling part 8,10.
Fig. 1 shows ring 6 and contacts the hydrocarbon fluid of outputs and the well screen 1 before that expands, thereby has gap 11 so that skin 4 is in unswollen state between the covering layer 4b and the borehole wall.
Fig. 2 shows ring 6 and contacts the hydrocarbon fluid of outputs and the well screen 1 afterwards that expands, thereby therefore skin 4 is by encircling the wall that 6 expanded radiallys make ring-type covering layer 4b contact pit shaft 2.
Fig. 3 shows well screen 1 and pit shaft 2 cross sections before ring 6 expansions.As shown in the figure, filtration beds 4a is made of a plurality of overlapped filters 5.Each filter 5 is connected on one or more rings 6 by corresponding flange (lug) 14 in its end, and overlapping with adjacent filter 5.Covering layer 4b is that filtration beds 4a provide enough protection thereby described longitudinal seam makes covering layer 4b have very big pliability to carry out expanded radially for thin metal cylinder has the sieve aperture that overlapping along the longitudinal direction longitudinal seam (not shown) constitutes.
Referring to Fig. 4, wherein show ring 6 after expanding screen casing 1 and the cross section of pit shaft 2.Skin 4 has expanded and has leaned against on the borehole wall, thereby sliding relatively appears in adjacent filter sheets 5 between the filtration beds 4a phase of expansion, and the seam of covering layer 4b broadens between the covering layer 4b phase of expansion.
For for simplicity, do not go out whole ring 6 and eyelet 7 in the accompanying drawing with designated.
In common use, screen casing 1 is run in the pit shaft 2 and is arranged in the reservoir that contains hydrocarbon fluid on stratum on every side, and therefore encircling 6 is in their unswollen states separately, and gap 11 be present in outer 4 and the wall of pit shaft 2 between (Fig. 1).When pit shaft 2 is produced, crude oil liquid stream from laminar flow peripherally go into pit shaft 2 and by outer 4 and eyelet 7 enter tubular part 3 thus.Therefore, stream of hydrocarbon fluid flows along ring 6, therefore encircles 6 and is transformed to swelling state (Fig. 2) from its unswollen state (Fig. 1).When expansion, thereby ring 6 leans against on outer 4 in propelling on the radially outer direction, thereby outer 4 expansions lean against on the wall of pit shaft 2.The expansion force that is applied by the ring group is along distributing on outer 4 the length direction, so outer 4 will adapt to the bigger scrambling of the borehole wall basically after it expands.Thereby because each filter 5 relative slips reduce the lap of adjacent filter sheets 5 between the filtration beds 4a phase of expansion, the screen size of filtration beds 4a can not change because of expanded radially.Thereby be chosen to can to make after filtration beds 4a expands enough overlapping of filter 5 maintenances to guarantee opening can not occur the degree of overlapping of adjacent filter sheets 5, described opening can make fluid walk around filtration beds 4a.
If desired, can obtain to encircle 6 acceleration and expand making well pump into pit shaft 2 by the fluid that diesel oil or other are fit to before producing.
Therefore then realized preventing the outside axial flow of stream of hydrocarbon fluid, thereby prevented that the sand grains or the clay particle that can local enter stream of hydrocarbon fluid from flowing in a longitudinal direction along whole outer 4 along skin 4.Because this flowing along whole outer 4 particle may cause the obstruction of whole filtration beds 4a, especially enter under the situation of pit shaft at clay particle, so the present invention has important advantage.
Other advantage of well screen of the present invention is to have annular space and the expansion mechanism between entity preboring tubular part, tubular part and the skin of high collapse resistance, described annular space provides good flow behavior for produced fluid, and described expansion mechanism has been avoided the needs of mechanical swelling tubular part.
Replace all rings and all made by the elastomeric material that expands when contacting hydrocarbon fluid, one or more rings can be made by the material that expands when contacting stratum output water.For example, described ring can comprise that first group is easy to the ring that expands and second group is easy to the ring that expands in water in hydrocarbon fluid, thereby first and second groups of rings are arranged in the mode that replaces.
In addition, replace each filter and all be connected on some or all rings in its end, any other suitable part of filter can both be connected on the described ring.In addition, described filter can keep in place so that do not need filter not being connected on some or all rings by covering layer.
As the tectal substitute mode of the slot with overlapping longitudinal seam, other suitable covering layer all can be used arbitrarily, for example have the collapsible covering layer of articulated section to allow covering layer to launch, the perhaps covering layer that constitutes by a plurality of interconnective small tubes, so each pipe flattens when covering layer expands.
