Detailed Description Of The Invention
Figure 1A and Figure 1B show the seal importing in the drilling well 102 with wall 104.Seal has baffle plate 106.Between baffle plate 106 and wall 104, there is gap 108.In upper area, baffle plate 106 is fastened on pipe 112 and in it towards the folding state of pipe 112.
Fig. 1 C and Fig. 1 D show it away from the baffle plate 106 of pipe 112 and the state that launches towards wall.The pressure being applied on baffle plate 106 by the fluid rising pushes baffle plates 106 facing to wall 104.As a result, between baffle plate 106 and wall 104, produce the connection of non-confirmation and/or confirmation and Fluid Sealing.Baffle plate 106 is closing gap 108 therefore.
In order to improve the sealing for the connection of fluid, for example the seal 200 of O shape cast formula can be attached on baffle plate 106.This is expressed as integral body and is expressed as details Z in Fig. 2 A and Fig. 2 B.By the fluid rising, be applied to the connection that pressure on baffle plate 106 causes confirmation between seal 200 and wall 104 and/or non-confirmation, Fluid Sealing.
Especially, if the pressure being applied on baffle plate 106 by the fluid rising is low, flexible fabric or film are attainable as baffle plate 106.On the other hand, the in the situation that of elevated pressures, the exemplary shown in Fig. 3 A and Fig. 3 B is preferred.In the case, reinforce rib-shaped piece 300 supporting baffle 106.In Fig. 3 A and Fig. 3 B, the not shown baffle plate 106 of reinforcing rib-shaped piece 300 more preferably to see is positioned at and reinforces the upstream of rib-shaped piece so that reinforce rib-shaped pieces 300 when baffle plate when launching 106 pushes.The structure of reinforcing rib-shaped piece 300 is similar to the bar assembly of umbrella part.Reinforce rib-shaped piece 300 and stablize baffle plate 106, make the pipe 112 in drilling well 102 placed in the middle, and the pressure on the baffle plate 106 while preventing from being in addition applied in it away from pipe 112 and towards the state of wall 104 expansion due to fluid damages baffle plate 106.
Especially, if the wall 104 of drilling well 102 is made by hard material, seal 200 is as shown in Figure 2 A and 2 B favourable.On the other hand, soft wall 104 makes to use the retaining element 302 that is shown as details Z in Fig. 3 A and Fig. 3 B.Retaining element 302 is attached to be reinforced rib-shaped piece 300 and is made by hard material.Especially, the material of retaining element 302 must be harder than the material of wall 104.Preferably, retaining element 302 has for example projection of barb form.
If the baffle plate 106 in it away from pipe 112 and the state that launches towards wall 104 is applied to the pressure extrusion wall 104 on baffle plate 106 by fluid, this makes the protruding transparent walls 104 of retaining element 302.Therefore, produce with wall 104 really lock be surely connected.
In order to save material and to improve safety, can mode progressively open baffle plate 106.In first step, retaining element 302 extruded wall 104, make the protruding transparent walls 104 of retaining element 302 and produce and determine that locking connects with respect to wall 104.In second step, by making baffle plate 106 become it to carry out closing gap 108 away from pipe 112 and the state that launches towards wall 104 from it towards pipe 112 folding state transformations.The present flowing pipe 112 of fluid.In third step, manage the valve existing in 112 and be closed.Therefore drilling well 102 is completely sealed.
In the situation that the exemplary shown in Figure 1A, Figure 1B, Fig. 1 C, Fig. 1 D, Fig. 2 A, Fig. 2 B, Fig. 3 A and Fig. 3 B, by the pipe 112 as the element of the equipment of drill string in preferred embodiments, baffle plate 106 is imported in drilling wells 102.On the other hand, the seal in Fig. 4 A, Fig. 4 B, Fig. 4 C and Fig. 4 D is designed to the form of torpedo.In this case, jet propeller 400 produces and is enough to overcome the fluid of rising seal is imported to the thrust in drilling well 102.
Except baffle plate 106, the seal shown in Fig. 4 A, Fig. 4 B, Fig. 4 C and Fig. 4 D has bellows 401.Bellows 401 has formed the outer encapsulating of the protrusion of seal.The bottom 401a of bellows 401 is hemispherical and is provided with sensor 110.
That adjoin with the hemisphere portion of bellows 401 is the cylindrical section 401b of bellows 401.The cylindrical section 401b of bellows 401 is connected the hemisphere portion 401a of bellows 401 with its top 401c.Successively with the top 401c of bellows 401 attached be induction element 402 and male part 404.
Bellows 401 use funnel-shaped recesses makes sealing propellants fill and hold device 408 and solid-state load-carrying unit 406.Pyrotechnics propellant fills and holds device 408 and be positioned at these grooves.
According to obtained data, sensor 110 is initiated propellant and is filled the startup of holding device 408.As a result, the energy discharging makes bellows 401 expansion or expansion and extruded wall 104.
Bellows 401 is provided with retaining element 302.The hardness of retaining element 302 must surpass the hardness of the wall 104 of drilling well 102.This make retaining element 302 because pyrotechnics propellant fills, hold device 408 startup and can transparent walls 104, thereby make seal anchor to wall 104 by determining that locking connects.As shown in the details Y of Fig. 4 C, retaining element 302 can be designed to barb.
The energy that propellant fills the blast of holding device 408 causes the diameter of at least a portion of bellows 401 to become large.In order to ensure the restriction distortion of bellows 401 in the case, bellows 401 can have predetermined breakaway poing 410, as shown in the details X in Fig. 4 B.When bellows 401 expands, the bottom of the bellows 401 consisting of the hemisphere portion 401a of bellows 401 and the cylindrical section 401b of bellows 401 is separated with the top 401c of bellows 401 along predetermined breakaway poing 410.This prevents when bellows 401 expands such as the remaining part of the seal of for example passage 414 or male part 404 impaired.
The gap existing between wall 104 and bellows 401 is larger, higher for the requirement of the deformability of bellows 401.In order to prevent surpassing the break limit for the material of bellows 401 when bellows 401 expands, bellows 401 can have vertically extending expansion fold below predetermined breakaway poing 410.
Under swelling state, the cylindrical section of bellows 401 is flatly bearing on wall 104.In the case, the hemisphere portion of bellows 401 is connected the cylindrical section of bellows 401 with the inside of seal.As a result, fluid can not overflowed between bellows 401 and wall 104.Now sealed drilling well.
In order to continue to use drilling well 102, seal to there is the valve 412 of the next-door neighbour's male part 404 as shown in the details Z of Fig. 4 D.Valve 412 opens and closes passage 414.When valve 412 cuts out, fluid can not overflowed from drilling well 102.On the other hand, when valve 412 is opened, fluid is got road by passage 414, and therefore passes through seal.
Except described disc valve 412, can also use the valve of other type, for example ball valve or slide-valve.Slide-valve has advantages of tensile force that need to be less.
Valve can also be opened when seal is inserted in drilling well, thereby reduces to act on the pressure on seal.Also there is the only possibility of shut off valve when pipeline is connected to male part 404.This pipeline 404 can absorb the part of increase power after valve cuts out.
A plurality of seals of realizing as shown in Fig. 4 A, Fig. 4 B, Fig. 4 C and Fig. 4 D can also be imported in drilling well 102.
Same feasible embodiment is that bellows is installed and imports in drilling well 102 as the element of the equipment of drill string 112.
Can combine various embodiments according to different security considerations.
Fig. 5 shows the part of the seal with at least one steady pin 500.In order to guide the object of at least one steady pin 500, carrier element 406 has cylindricality bore hole 502.Steady pin 500 is mounted for and can in bore hole 502, be shifted.
Bore hole 502 is connected to spherical fire chamber 506 by the opening in bellows 401 504.Be similar to bore hole 502, fire chamber 506 is arranged in carrier element 406, that is, fire chamber 506 is surrounded by carrier element 406 or consisted of carrier element 406.
Bore hole 502 out of plumb are extended, but with respect to vertically to downward-sloping at a certain angle.As a result, due to its gravity, first steady pin 500 slides along bore hole 502 in the direction of seal inside.
Fire chamber 506 comprises propellant and fills and hold device 408.When propellant fills when holding device 408 and being activated, the energy drives steady pin 500 discharging along the direction of the wall 104 of drilling well 102 away from fire chamber 506.Therefore, steady pin 500 is through existing in the gap 108 between bellows 401 and wall 104, and transparent walls 104.Seal is now fixed to wall 104.
As mentioned above, by making bellows 401 launch or expand, bellows 401 extruded wall 104 can be closed and make in gap 108.Therefore, at least one propellant fills and holds device 408 and play the effect that bellows is launched or expand, and at least one other propellant fills and holds device 408 steady pin 500 is driven in wall 104 simultaneously.
In order to prevent that bore hole 502 and at least one steady pin 500 are impaired when bellows 401 launches or expand, bore hole 502 is preferably arranged so that the opening 504 in bellows 401 is arranged in the top of predetermined breakaway poing 410 of the top 401c of bellows 401.
