Background technology
Wire-element for example light transmitting fiber is very useful in the sense operation of signal transmission and many industries.One of described industry is that hydrocarbon is surveyed and manufacturing.Light transmitting fiber has very large superiority than other method of creeping into transmission signals or detected parameters downwards.Yet, because light transmitting fiber must be laid very long distance, and since the difficulty that the collision of instrument when light transmitting fiber is run through pore and pore housing causes therefore, effectively light transmitting fiber is transported to the target location and remains one than difficult target.
Telecommunications industry is developed the fibre-optic method of a kind of installing, and this method utilizes the viscous resistance of fluid on light transmitting fiber to distribute tractive load along the fibre length direction.This method can " blow light transmitting fiber " in the pipeline of prepackage, and can make the light transmitting fiber mobile phase to longer distance effectively.Yet,, between starting point and land, must form pressure gradient in order to produce fluid stream.Magnitude of pressure differential is proportional with the sectional area that will run through fibre-optic duct length of installing and pipeline.Because in the oil field, length may be up to 35000 feet, and required pressure reduction can be very high.An example is, the water that utilizes 5700 pounds/square inch starting point pressure to move 0.15 gallon passes the pipeline of long 35000 feet, 0.250 inch external diameter * 0.152 inch internal diameter.Under big like this pressure, blow fiber and can produce serious problem obviously.That is to say that described pressure will act on the cross section of selected fiber, thereby fiber is released from pipeline, rather than make fiber move into pipeline.
Can overcome described defective be used for insert fiber method and the device will fully be approved by industry.

Fig. 2 is the perspective exploded view of a similar embodiment of the present invention.
Embodiment
With reference to accompanying drawing, demonstrate the embodiment that wire-element inserts device 10.Insert device 10 and comprise housing 12, this housing comprises base 14 and lid 16.But described base is connected to pressure seal each other with lid, so that form a pressure vessel, thereby the interior pressure of described container can be set to such an extent that will be laid in wherein the interior pressure of tube-like piece more than or equal to thread (class) element.Described wire-element can be an any kind, for simplicity, hereinafter is called " fiber " (type), is not in order to limit the scope that the present invention asks for protection.In diagram, described lid for example is bolted on the base by a plurality of threaded fasteners, yet, should be understood that for example directly lid being screwed on the base or using the alternative arrangements of latch piece or similar device is applicable too.Housing 12 comprises fluid intake 18, fiber entry 20 and fluid/fiber outlet 22.Fluid egress point 22 can link to each other with short length tubular 24, and fiber 26 can be subjected to forward power by this tube-like piece, is deployed in the target tubular (not shown) being used for.The inside dimension of described short length tubular 24 narrower (diameter is limited) so that make inflow fluid wherein flow sooner, thereby produces bigger fluid drag force on fiber 26.This is useful when just beginning to send to, and it helps to send in the system fiber enough far away---as long as the fluid drag force is greater than kick.Yet, replace necessary length for real balance fluid drag force and kick in order to use short length tubular 24, need extra insertion force.Instructed the method and apparatus of using this insertion force in this manual.
As disclosed herein, thereby mechanical force is applied in required the making a concerted effort of acquisition on fiber on the fiber, to prevent the generation of back seat phenomenon.In housing 12, be provided with capstan winch 28.Capstan winch 28 is driven by drive unit 30, and this drive unit can be belt transmission as shown in the figure in one embodiment.Belt 32 can be by any applicable drive system motor driven for example.Under this situation with capstan arrangement, drive unit rotates and makes capstan winch around its axis rotation.Except capstan winch 28, also be provided with spiral guiding piece 34, this guiding piece functionally links to each other with fiber 26 with respect to capstan winch 28, and is fixed in such a way on the housing 12, be that spiral guiding piece 34 does not rotate with capstan winch, but remain close to the surface of capstan winch 28.Except fiber is engaged with capstan winch at an axial end portion, to leave outside the capstan winch at another axial end portion, guiding piece 34 purposes own are to reduce owing to fiber causes fiber 26 that the possibility of tangling takes place around capstan winch 28 multi-turns.By for example groove of spiral fashion (or spiral form) path is set, perhaps for example limit the structure of groove, fiber 26 can be directed as described above.With reference to accompanying drawing 2, can observe guiding piece 34 best, guiding piece decomposes from housing in the figure.In the present embodiment as can be seen, guiding piece 34 comprises that inside is provided with the tubular supporting piece 36 of spiral 38.Spiral 38 is open towards its inner space, thereby for the fiber that is positioned at wherein provides the passage that leads to capstan winch 28 surfaces, so that actuation force can be applied on the fiber 26 when needed.As can be seen, be provided with fiber in the guiding piece 34 and portal 40, this fiber portals tolerable fiber 26 across and into fluid/fiber outlet 22.Can see that also a similar fiber hand-hole 42 is arranged in guiding piece 34.This fiber hand-hole allows that fiber enters guiding piece 34, and is wrapped on the capstan winch 28.As previously mentioned, described guiding piece 34 does not rotate with respect to housing 12, therefore comprises the feature that prevents this rotation.These features can be pin 44 as shown in the figure, and described pin hangs down from support member 36, and insert in the shrinkage pool (not shown) of housing, relatively rotate preventing; Perhaps can be around support member 36 settings and with the O shape ring (not shown) that the mode with housing 12 interference engagement is received, perhaps can be that other prevents means in relative rotation.The fiber 26 that is connected with guiding piece 34 operability advances around capstan winch 28 in the helicla flute of spiral guiding piece 34, portals by fiber then and 40 leaves guiding piece 34 and leave housing 12, and pass fiber and fluid egress point 22 with pressure fluid.
Should be noted that fluid intake 18 can be used for any fluid media (medium), no matter be liquid or gas, for example water or air.The pressurization of housing 12 allows to balance each other through outlet 22 and the hyperbaric environment that will lay the tube-like piece of fiber.As indicated above, the pressure that exports in the tube-like piece 24 of 22 outsides is very big.In a kind of applicable cases, pressure is 5700 pounds/square inch.So big pressure makes importing fiber 26 very difficult, because pressure acts on the sectional area of fiber, fiber to pushing back from tube-like piece 24, is therefore needed mechanically to insert.Yet be well known that light transmitting fiber can not bear effect force of compression (for example, along its axial force of compression) thereon well.The less relatively axial compression load that is applied to it also can cause specific damage to fiber.Yet,, when keeping insertion force, can avoid this compressive load according to the present invention.
When for example only having the physics tension force from tube-like piece 24 on the fiber 26 of the downstream end of housing 12, capstan driving device just can apply driving force to fiber 26.Such power fraps on capstan winch 28 fiber, thereby makes capstan winch can drive fiber.If do not have tension force on fiber 26, capstan winch will only rotate by centering in the formed fibrous loop circle of some circle fibers of capstan winch 28.It is very little to impose on the insertion force of fiber by capstan winch like this.Be prevented from as fruit fiber action forward is accidental, even less degree, tension force required on the fiber also will reduce, and capstan winch will stop to drive fiber naturally.Therefore, under any circumstance, when laying was subjected to hindering, fiber can not be damaged.In one embodiment, the fluid drag force that acts on the fiber provides enough tension force separately, drives so that cause capstan winch.
In an embodiment of the disclosed device of this instructions, capstan winch 28 can be from housing 12 dismountings, so that manually twine fiber 26 around capstan winch.The fiber that is wrapped on the capstan winch 28 passes through short tubular pieces 24 by all feedings.Then, capstan winch is placed in the housing 12 in the mode that engages with drive unit.This joint can be gearing mesh or any other connected mode easily.In case capstan winch is suitably twined by fiber, and be installed onto on the housing base 14, be fixed on the base 14 with then will covering 16 pressure seals, thereby form pressure-tight housing 12.Target tubular links to each other with short tubular pieces 24 by any conventional equipment, and the starter motor drive unit is so that the capstan winch rotation.As mentioned above, when not having tension force on fiber 26, fiber does not just frap on capstan winch, and does not have the Mechanical Driven masterpiece to be used on the fiber.Capstan winch can hurtful mode not rotate, is fed into fluid intake 20 under the effect of fluid at pressure in the spiral circle of fiber.Apply hydrodynamic pressure to fluid intake 20 and make that producing the fluid that passes fluid and fiber outlet 22 flows.When fluid stream increased, the fluid drag force that acts on this part fiber 26 in the short tubular pieces 24 began to pull fiber.Thereby when the fluid drag force increased to enough degree produce tension force on fiber, fiber became and fraps on capstan winch, thereby made the capstan winch can be to fibre application machine tool insertion force.The insertion of fiber will last till always that reaching desired depth or fluid stream stops or being reduced to being lower than frap threshold value or fiber is mechanically hindered in some way or any other power stops or slowing down this insertion, fiber will stop capstan winch being applied the fiber necessary tension force on capstan winch that fraps itself this moment, and capstan winch will rotate in the fiber spiral wound convolution of capstan winch harmlessly.
Though illustrated and described preferred embodiment, under the situation that does not deviate from the spirit and scope of the present invention, can change or replace to described embodiment.Therefore, should be appreciated that the present invention is illustrated by diagram, but this is not construed as limiting.
