In the description of the present application, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.
In order to solve the technical problems that in the prior art, the measurement size information of an assembled suspension device is not accurate enough, and a larger reference error exists when a tool is installed in a subsequent well, so that the suspension device of the wellhead 1 is difficult to accurately assemble in the wellhead 1; to this end, an embodiment of the invention provides a wellhead 1 suspension device.
Detailed description of embodiments of the invention the following detailed description provides a specific construction of a wellhead 1 suspension device comprising a suspension sleeve 2, a stop 3 and a push assembly 4 according to the specific construction of the wellhead 1 suspension device shown in figures 1-6.
The suspension casing 2 is arranged in the accommodating cavity 11 of the wellhead 1; the suspension bushing 2 is hollow and formed with an opening-provided through hole 21. Specifically, the suspension casing 2 is arranged in the wellhead 1, so that the function of supporting and protecting wellhead equipment is achieved. For example, wellhead blowout preventers, wellhead dividers, and the like, are capable of withstanding the weight and pressures experienced by such wellhead equipment, thereby ensuring that the wellhead equipment is capable of stable operation.
The outer side wall of the suspension sleeve 2 is tightly abutted with the cavity wall of the accommodating cavity 11 of the wellhead 1; the well head equipment is protected from being corroded and damaged by the external environment; meanwhile, the well head 1 can resist the corrosion of gas and liquid, prevent the leakage of mud and drilling fluid, and reduce the abrasion and damage to well head equipment and the pollution to the outside.
To enable the suspension casing 2 to be fixed in the wellhead 1; for this purpose, according to fig. 1, the limiting element 3 is arranged between the outer side wall of the suspension sleeve 2 and the cavity wall of the receiving cavity 11; a locking groove 112 is concavely arranged on the cavity wall of the accommodating cavity 11. Specifically, when the limiting piece 3 is pushed into the locking groove 112 during assembly, the limiting piece 3 extending to the locking groove 112 at least partially protrudes out of the locking groove 112, so that the limiting piece 3 is clamped on the hanging sleeve 2, further the hanging sleeve 2 is fixed, the hanging sleeve 2 is prevented from shaking along the axial direction, and the hanging sleeve 2 is positioned, so that the hanging sleeve 2 can be accurately assembled in the wellhead 1.
When the casing is detached, the stopper 3 is released from the locking groove 112, and at this time, the stopper 3 cannot be locked to the casing 2 by the locking groove 112, so that the whole casing 2 can be taken out from the wellhead 1.
To enable the fixed assembly of the suspension casing 2 or the disassembly of the suspension casing 2; to this end, as shown in fig. 1, in particular, the pushing assembly 4 comprises a pushing member 41 and a moving member 42; the moving member 42 is movably inserted into the through hole 21, and the pushing member 41 is fixedly arranged on the outer side wall of the moving member 42; when the moving member 42 moves axially, the pushing member 41 is used to push the limiting member 3 into the locking groove 112, so that the suspension sleeve 2 is fixed in the accommodating cavity 11.
Specifically, when the pushing member 42 moves along the axial direction of the through hole 21, the pushing member 41 is driven to move along the moving direction of the moving member 42 until the pushing member abuts against the limiting member 3 and pushes the limiting member 3 to move into the locking groove 112, and the limiting member 3 is locked to the suspension sleeve 2, so that the suspension sleeve 2 is accurately assembled.
For example, as shown in fig. 2 and fig. 3, when the suspension sleeve 2 is assembled, the moving member 42 is moved downward in the through hole 21, so that the pushing member 41 is synchronously driven to move downward to be capable of abutting against the limiting member 3, and the positioning assembly of the suspension sleeve 2 can be completed after the limiting member 3 is pushed to move radially to be capable of extending into the locking groove 112; conversely, when the hanging sleeve 2 is disassembled, the moving part 42 moves upwards in the penetrating hole 21, so that the pushing part 41 is driven to move upwards to be staggered with the limiting part 3 in the axial direction, and the limiting part 3 is reset and completely separated from the locking groove 112, so that the hanging sleeve 2 can be taken out.
Since the outer side wall of the movable element 42 is slidably abutted against the side wall of the wellhead 1, the movable element 42 is guided by the side wall of the wellhead 1 when the movable element 42 moves in the axial direction, so that the stability of the movable element 42 in the moving state is improved.
In summary, when the moving member 42 moves axially in the through hole 21 of the hanging sleeve 2, the pushing member 41 is driven to push the limiting member 3 into the locking groove 112, and the hanging sleeve 2 is locked by the limiting member 3, so that the hanging sleeve 2 is fixed in the accommodating cavity 11, and the hanging sleeve 2 can be accurately assembled in the wellhead 1, so that the technical problem that the hanging sleeve 2 is difficult to position and assemble is solved.
In a particular embodiment, according to fig. 5, the outer side wall of the suspension bushing 2 is concavely provided with a catch groove 22, and the inner side wall of the stop member 3 is provided with an inner flange 31 for extending into the catch groove 22. Specifically, when the pushing member 41 pushes the stopper 3 into the locking groove 112, since the inner flange 31 extends into the locking groove 22, accurate fitting of the suspension casing 2 into the accommodation chamber 11 of the wellhead 1 is achieved.
It will be appreciated that when the retainer 3 is pushed into the locking groove 112, the length of its inner flange 31 protrudes beyond the locking groove 112 and into the catch groove 22, thereby serving to catch the suspension sleeve 2.
In a specific embodiment, a positioning portion 111 is provided on the wall of the housing cavity 11 of the wellhead 1 for positioning the hanging casing 2. Specifically, when the suspension tube 2 is inserted into the accommodating chamber 11 and moves in the axial direction to come into contact with the top of the positioning portion 111, the positioning portion 111 prevents the suspension tube 2 from moving further, thereby functioning as a positioning.
In some alternative embodiments, the positioning portion 111 is two of:
In one embodiment, the positioning portion 111 has a ring shape.
In another embodiment, the positioning portion 111 is provided in plurality (a plurality of positioning portions 111 are provided along the circumferential direction of the housing chamber 11 of the wellhead 1), and the specific embodiment is not limited.
In a further embodiment, the top of the positioning portion 111 forms a slope, and the outer side wall of the suspension sleeve 2 forms a slope matching with the slope; with this arrangement, when the inclined surface of the suspension casing 2 abuts against the inclined surface of the positioning portion 111, the suspension casing 2 is locked, thereby preventing further movement in the housing chamber 11 of the wellhead 1 of the suspension casing 2.
According to fig. 1, in a specific embodiment, a step 411 is provided on the outer sidewall of the moving member 42, and is used to lock the moving member 42 when the moving member 42 moves to the position where the step 411 abuts against the top of the suspension collar 2. Specifically, since the moving member 42 is configured to drive the pushing member 41 to move along the axial direction to define the moving distance of the pushing member 41, when the moving member 42 moves in the accommodating cavity 11, the bottom of the step 411 abuts against the top of the suspension sleeve 2, so that the moving member 42 cannot move further, and at this time, the pushing member 41 can abut against the limiting member 3 and push the limiting member 3 to move into the locking groove 112, thereby limiting the moving range of the moving member 42.
In a specific embodiment, as shown in fig. 4, a first thread 412 is provided on the outer sidewall of the moving member 42, and a second thread 211 for connecting with the first thread 412 is provided on the wall of the through hole 21. Specifically, when the moving member 42 is twisted to rotate in the circumferential direction, the moving member 42 is connected to the second thread 211 through the first thread 412, so that the moving member 42 can move in the axial direction, and since the pushing member 41 is fixedly disposed on the moving member 42, the moving member 42 can drive the pushing member 41 to move in the axial direction; therefore, when the hanging sleeve 2 is assembled or disassembled, the moving piece 42 is only required to be along the circumferential direction (clockwise or anticlockwise as understood), so that the pushing piece 41 is driven to push the limiting piece 3 to move into the locking groove 112 or separate from the locking groove 112, and the assembly difficulty and labor intensity of workers are reduced.
To enable stable pushing of the pushing member 41 to the stopper 3; for this purpose, in a specific embodiment, the top of the limiting member 3 is formed with a first inclined surface 32 or an arc surface, and the bottom of the pushing member 41 is provided with a second inclined surface 413 that mates with the first inclined surface 32 or the arc surface.
In the specific pushing process, when the pushing member 41 moves to the position where the second inclined surface 413 is abutted to the first inclined surface 32 or the cambered surface, the pushing member 41 can move to the side face abutted to the limiting member 3 under the guiding action of the first inclined surface 32, so as to push the limiting member 3 into the locking groove 112, thereby improving the stability of the pushing member 41 in the process of pushing the limiting member 3, and preventing the situation that the top of the limiting member 3 is blocked on the pushing member 41.
It will be appreciated that the limiter 3 of the present embodiment has two types:
In one embodiment, the limiting piece 3 is a locking ring with elastic property, the locking groove 112 is an annular groove, and the pushing piece 41 is annular; thus, when the pushing member 41 moves to abut against the inner sidewall of the locking ring, it is formed to press the locking ring so that the outer diameter of the locking ring is increased to be able to be inserted into the locking groove 112; if the pushing member 41 moves to be staggered with the inner sidewall of the locking ring, the locking ring is restored to its original shape, i.e., is contracted and deformed in the radial direction to reduce the outer diameter thereof, thereby being separated from the locking groove 112.
In some alternative embodiments, the locking ring is one of a rubber sleeve, a silicone sleeve or a polyurethane sleeve, which is not limited in particular.
In another embodiment, the limiting piece 3 is a plurality of beads, the beads are movably arranged on the circumference of the suspension casing 2, and locking grooves 112 which are in one-to-one correspondence with the number of the beads are arranged along the circumference of the wellhead 1; thus, when the pushing member 41 moves to be capable of abutting against the plurality of beads at the same time, the plurality of beads are pushed to move into the locking groove 112 in the radial direction at the same time, and the hanging sleeve 2 is locked by the portions of the plurality of beads protruding from the locking groove 112, so that the hanging sleeve 2 is fixed.
To stably push the stopper 3 into the locking groove 112; for this, according to fig. 2, in a specific embodiment, an inclined surface 1121 is formed at the top of the locking groove 112 for guiding the stopper 3 to be pushed to the locking groove 112 or to be separated from the locking groove 112. Specifically, since one end of the inclined surface 1121 is inclined toward the locking groove 112, when the pusher 41 pushes the stopper 3, the stopper 3 is moved in the inclined direction of the inclined surface 1121 until it can be fixed in the locking groove 112; when the pushing piece 41 is staggered with the limiting piece 3, the limiting piece 3 can be quickly reset under the guiding action of the inclined surface 1121, so that the efficiency of the worker for disassembling and taking out the hanging sleeve 2 is improved.
Resetting the stopper 3 pushed into the locking groove 112; to this end, in a specific embodiment, the outer side wall of the suspension bushing 2 is provided with an outer flange 23, which outer flange 23 is adapted to push the stop member 3 against the push member 41 into the locking groove 112 when the push member 41 is moved into abutment with the compression ring.
Specifically, when the outer side surface of the pushing member 41 moves to abut against the limiting member 3, the outer flange 23 abuts against the inner side surface of the pushing member 41, that is, the outer flange 23, the pushing member 41 and the limiting member 3 are at the same height, so that the pushing member 41 is pressed against the limiting member 3 to the locking groove 112, the limiting member 3 can be stably fixed in the locking groove 112, deformation and reset cannot be performed, the phenomenon that the limiting member 3 is easy to reset is avoided, and the stability of the suspension sleeve 2 is further improved.
In a further embodiment, the top of the outer flange 23 is formed with an inclined surface; this arrangement guides the pusher 41 so that the pusher 41 can be moved to the outer side thereof to abut the stopper 3.
In a specific embodiment, the through hole 21 is a tapered hole, and the portion of the moving member 42 inserted into the accommodating cavity 11 is tapered. Therefore, when the moving part 42 is inserted into the tapered hole, the hole wall of the tapered hole can play a role in guiding the moving part 42, so that the moving part 42 can be quickly inserted into the tapered hole, and convenience in assembling the moving part 42 in the hanging sleeve 2 is realized.
It should be noted that, the second thread 211 of the present embodiment is disposed on the wall of the tapered hole, so that when the moving member 42 is inserted into the tapered hole, the first thread 412 is convenient to be quickly connected to the second screw hole.
In a specific embodiment, the outer sidewall of the pushing member 41 is in interference fit with the wall of the through hole 21; by the arrangement, the contact area between the pushing piece 41 and the hole wall of the penetrating hole 21 is increased, so that the pushing piece 41 is more stable, and can bear larger load; in addition, the clearance between the pushing member 41 and the wall of the through hole 21 is reduced, the relative fixing degree and the connection rigidity of the pushing member and the wall of the through hole 21 are increased, and strong shaking and noise generated by the clearance between the pushing member and the wall of the through hole are avoided.
While the invention has been described with reference to certain preferred embodiments, it will be understood by those skilled in the art that various changes and substitutions of equivalents may be made and equivalents will be apparent to those skilled in the art without departing from the scope of the invention. Therefore, the protection scope of the invention is subject to the protection scope of the claims.
