The specific embodiment
Fig. 1 represents device according to an embodiment of the invention or instrument 10, and it is suspended on by cable 14 for example is that this cable provides power, data communication and physical support in the pipe 12 of casing.The device of instrument 10 comprises tool body 16, and it has power and control electronic equipment, pump and hydraulic fluid supply and sensor (not shown).Operation head 18 is arranged on the lower end of tool body 16.Instrument 10 can be arranged in centre bore portion alternatively, to allow the (not shown) that circulates.
Be understandable that pipe 12 can be one that is used in many tube elements of oil or gas well, for example sleeve pipe, bushing pipe, pipeline etc.Pipe 12 also can be to be used for a kind of in the many kinds of pipes of ground, seabed or underground pipeline.Will also be appreciated that pipe 12 can be solid, fluting or the punching form.
Fig. 2 represents the details of head 18, and it comprises main head 20, and this main head is connected to tool body 16 and limits cylinder 22 at its lower ending opening.Axial axis 24 extends from the bottom of cylinder 22 and has an end plate 26 that is connected thereto.Piston 28 is slidably mounted in the cylinder 22 around axle 24.30 of piston 28 has bigger diameter than the part 32 that is contained in the cylinder hole 22, and 30 external diameter is roughly corresponding to the external diameter of tool body 16.Polyurethane rings 34 is installed between piston head 30 and the end plate 26 around axle 24.It also has and the roughly corresponding external diameter of tool body 16 external diameters.Being arranged in the compressed fluid that working spaces 36 below the piston 28 are connected to tool body 16 in the cylinder 22 supplies with on the (not shown).
It should be noted that in other embodiments of the invention, replaced ring 34, can between piston head 30 and end plate 26 thick cyclinder be installed around axle 24, this cylinder can be as the expander in the instrument 10.The material of making ring 34 or cylinder can be the flexible and elastomeric material of any other type, for example rubber.And ring 34 or cylinder can comprise a plurality of parts, and it can form independent part.These parts can be encapsulated in the compartment of given shape, thus around axle 24, zone between piston head 30 and end plate 26.
In the position shown in Fig. 1 and 2, compressed fluid does not enter working space 36 as yet, not compression of ring 34.Instrument 10 has substantially invariable external diameter like this, and can run to the position of any concern in sleeve pipe 12.In this example, work 10 is used for forming " clock " or being called as the diameter amplifier section in chamber at sleeve pipe 12, thereby can be used for the expansion of conventional expanded instrument.
When instrument 10 was positioned at the bottom of the part that obtains expanding, compressed fluid entered working space 36.Force piston 28 to leave cylinder 22, thus extruding 30 and end plate 26 between ring 34.This extruding action causes ring 34 around its periphery projection, thus the outstanding external diameter (as shown in Figure 3) that surpasses instrument 10 remainders.The periphery projection 38 of ring 34 causes that sleeve pipe 12 permanently is out of shape 40, as shown in Figure 4.
When remaining on its squeezed state, instrument 10 advances subsequently by sleeve pipe 12 (along the direction z among Fig. 5) at ring 34, and when instrument 10 moved, the ring of extruding forced sleeve pipe 12 40 (referring to the Fig. 5) that permanently expand.In case sleeve pipe 12 suitable length L expand, then discharge the pressure that encircles on 34 by discharging fluid from working space.Ring 34 is got back to its unexpanded position (as illustrated in fig. 1 and 2) subsequently, and instrument 10 can move to the not another location of dilation of sleeve pipe 12.In this dynamic mode, the maximum, force that can provide by cable is provided the maximum ga(u)ge of the tube element that can expand by this technology.Sliding agent and or the existence of lining also will exert an influence.
In optional embodiment, instrument can be for example by adopting heavy drill string to move down in the well of near vertical.
In the above-described embodiments, instrument 10 can drop to the degree of depth that it begins according to circumstances on cable 14 or by pipeline, the pipe that twines, and rises then so that casing length L expands.Also can begin to expand, and then for example force instrument descending by compressed fluid being pumped in the sleeve pipe on the instrument 10 at the top of sleeve pipe.
To the described piston that is used for extrusion ring and the layout of cylinder many distortion can be arranged.For example, can adopt polytype mechanical arrangement, for example power screw and nut or rack-and-pinion are arranged, perhaps be used for mobile piston as described above, perhaps alternatively, keep " piston " static and end plate is mentioned towards it, to obtain identical effect.
Multiple sensors can be set to monitor its operation and typically to provide feedback in instrument, instrument in using accurately be controlled with permission by cable.
Although the example that provides above is that the present invention can find purposes in many application about formation chamber or clock in sleeve pipe 12.For example, be not that the part of sleeve pipe is expanded being used for the expansion of another bloat tool, but it can be as the main expanding method of whole sleeve pipe.In addition, its ability that is released and moves through unexpanded sleeve pipe means that it can be used to provide a plurality of by the separated differential expansion part of bulge not.Use in the expansion fashion that the expansion that provides can propose in front, for example avoid the reducing step by step of flow diameter of cement and well, the connection of sleeve portion is used to insert the formation of the dilation of continuous cannula portion, an expansion on opening wellhole or existing sleeve pipe, or the like.Alternatively, potted component, for example O circle or coating can be arranged on the expander, so that better elastic packing to be provided.
In optional embodiment, expander is one or more rings 34 or one or more lining, can be surrounded by the topping that for example is closure assembly, to be used to provide more wear-resisting and more long-life expander.Except around expander, covering fully, also can be that several parts of expander are covered by the protective material layer, to improve abrasion resistance.
Expansion effect can change according to the size of instrument, particularly the size of polyurethane rings.Thicker ring will allow from green diameter potential have a bigger expansion, as bigger piston or hole stroke are arranged.Although polyurethane-base is the preferred material that is used to encircle in its elasticity, especially after removing, gets back to pressure the ability of its original size, and bigger wear and shock-resistant ability and bigger temperature range of operation, yet also can use other similar materials.When instrument was mobile under its expanded form, polyurethane is also enough smooth can to slide it on sleeve surface.Sliding agent/Teflon layer or both can provide as auxiliary, preferably green soap.
The present invention can also be used to form the expansion of one or more parts, for example as shown in Figure 4.Single expansion like this can be used for tube element is anchored on together (support).If pipe may be out of shape after installing or in the follow-up life cycle at well, then a series of these expansion phases can be used for the stress elimination or prevent canal curvature closely being arranged together.This distortion may be for different reasons, and for example the degree of depth of well causes compressing.By making head be positioned at as shown in Figure 4 position, entire tool 10 can be used as anchor, provides another instrument that allows to be connected thereto to move through the reaction force of well.In order in power expands, effectively to use and to clamp better, may need to strengthen, for example need bridging plug or packer (packer).Cutter, wear-resistant pad etc. can be installed/be moulded in the ring.In addition, a plurality of rings can expand by one or more pistons.Other application of this technology and distortion will be conspicuous.
