Description
Technical Field
The invention relates to the technical field of petroleum well completion, in particular to a running tool. The invention also relates to a liner hanger for use with the running tool. The invention also relates to a liner hanger assembly comprising the liner hanger and a running tool.
Background
The liner hanger is a well tool commonly used in the current petroleum exploration and development, and can be divided into three types, namely a mechanical type, a hydraulic type and a hydraulic mechanical double-acting type according to different sitting and hanging modes. Hydraulic liner hangers are most widely used. Traditional fluid pressure type liner hanger sit and hang actuating mechanism design outside the hanger body, will stay in the well for a long time after the well cementation construction, owing to sit and hang actuating mechanism unavoidably need use rubber seal, and rubber seal is easy ageing under the high temperature high pressure environment in the well for a long time, leads to sitting to hang actuating mechanism department and seals up inefficacy to influence the sealed permanence of whole pit shaft.
Therefore, the research on the liner hanger technology with the recyclable driving mechanism is carried out at home and abroad one after another, and the potential risk point and weak point that the driving mechanism is left in the well for a long time are eliminated. Due to the change of the way the liner hanger is set, a special anti-advance setting mechanism needs to be designed on the running tool to prevent the liner from being set in advance during the liner running (for example, refer to US20180223615a 1). After the tail pipe is put in place, the locking is released through the pressure build-up in the pipe, so that the pressure build-up is continued to realize the operations of hanging the slips, releasing the tail pipe and the like. However, if the pressure holding cannot be normally realized in the pipe, the unlocking cannot be completed, so that the pipe cannot be released, and a serious safety accident is caused. Although this patent has designed special shearable dog, can realize the separation of running tool and tieback section of thick bamboo through lifting by force, this mode has solved the problem of unblock, has increased the risk that sets in advance in the tail pipe running-in process to can't reach the demand of preventing to set in advance and hang completely. This is because this solution places very strict requirements on the shear value of the shearable blocks. If the shear value is large, the load required for field lifting is large, and the shearing requirement may not be met when the tail pipe is light in weight. If the set shear value is small, the tail pipe can be cut off in advance due to the resistance of lifting and lowering in the tail pipe lowering process or the possibility of catching, so that the tail pipe hanger can be hung in advance.
In addition, due to the often complex well environment, the hanger sometimes experiences a loss of seating. Also, because the environment inside the well is very complex, the operator may not know exactly whether the hanger is seated or not in some cases. Under these circumstances, subsequent releasing and cementing operations cannot be performed, and the difficulty and risk of field operations are greatly increased.

Detailed Description
The invention will be further explained with reference to the drawings.
Fig. 1-6 show a first embodiment of a tailpipe suspension assembly 1000 according to the present invention. As shown in FIG. 1, a liner hanger assembly 1000 includes a running tool 100 and a liner hanger 200.
FIGS. 2 and 3 show the construction of the running tool 100 in detail. The running tool 100 includes a mandrel 110 that extends in an axial direction. The upper end of the mandrel 110 may be connected to an upstream string by an upper sub. The running tool 100 further includes a coupling mechanism 120, a setting and hanging drive mechanism 130, and a releasing mechanism 140, which are sequentially fitted over the mandrel 110 from top to bottom. It should be understood that the mandrel 110 may be constructed as a single piece or may be formed from multiple pieces joined together.
The coupling mechanism 120 includes a coupling sub 122 fixedly received on the mandrel 110. The fixed socket can be realized, for example, as follows. A fixing coupling hole 122A penetrating the coupling joint 122 in a radial direction is configured at an upper end of the coupling joint 122. A joint connection block 121 is provided in the fixed connection hole 122A. The shape of the fixed connection hole 122A is matched to the shape of the joint connection block 121 to restrict axial and circumferential movements of the joint connection block 121 with respect to the fixed connection hole 122A. A corresponding cover plate is provided on the outside of the joint connector 122 for covering the joint connector block 121 and restricting its radially outward movement. A corresponding joint connection slot 110A is formed on the outer side wall of the spindle 110. The joint coupling groove 110A corresponds to the positions of the fixed coupling hole 122A and the joint connection block 121 such that the joint connection block 121 can be inserted into the joint coupling groove 110A to extend radially inward. The joint connection groove 110A is configured as a slit extending in the longitudinal direction to restrict the radial movement of the joint connection block 121 with respect to the mandrel 110 and to allow a certain axial movement range of the joint connection block in the axial direction with respect to the mandrel 110.
It should be understood that the fastening connection bore 122A can alternatively be produced as a blind bore, whereby the outer cover plate can be dispensed with.
In a preferred embodiment, a plurality of fixing coupling holes 122A spaced apart from each other are uniformly distributed in the circumferential direction of the coupling joint 122, and a plurality of joint connection blocks 121 and joint coupling grooves 110A are correspondingly provided.
As also shown in fig. 2 and 3, the coupling mechanism 120 further includes a coupling sleeve 124 disposed below the coupling sub 122. The connection sleeve 124 is detachably connected to the connection joint 122. The connection is as follows. A joint stopper hole 122B penetrating the connection joint 122 in the radial direction is configured at the lower end of the connection joint 122. A coupling sleeve fixing block 123 is provided in the joint stopper hole 122B. A fixing block receiving groove 124B is formed at an inner side of an upper end of the coupling sleeve 124. The upper end of the connecting sleeve 124 extends axially upward to fit over the lower end of the connecting joint 122, so that the fixing block receiving groove 124B is aligned with the joint limiting hole 122B, and the connecting sleeve fixing block 123 can extend radially outward into the fixing block receiving groove 124B. The joint stopper hole 122B is shaped to match the shape of the coupling sleeve fixing block 123 to restrict the movement of the coupling sleeve fixing block 123 in the circumferential and axial directions. The fixing block receiving groove 124B may be configured, for example, as an annular groove that is form-fit with the coupling sleeve fixing block 123 to limit axial movement of the coupling sleeve fixing block 123 relative to the coupling sleeve 124. In addition, an extension sleeve 126 is further sleeved between the lower end of the connecting joint 122 and the mandrel 110. The extension sleeve extends to the inside of the coupling sleeve fixing block 123 for restricting the radial movement of the coupling sleeve fixing block 123. That is, when the extension sleeve 126 is positioned at the inner side of the coupling sleeve fixing block 123, the coupling sleeve fixing block 123 is extended radially outward into the fixing block receiving groove 124B of the coupling sleeve 124. When the extension sleeve 126 moves downward to be separated from the coupling sleeve fixing block 123, a free space is formed inside the coupling sleeve fixing block 123. The coupling sleeve fixing block 123 can be moved radially inward to be disengaged from the fixing block receiving groove 124B.
In addition, at least one (preferably a plurality of) joint rotation preventing grooves 122D extending in the axial direction are also configured at the lower end of the joint 122. Correspondingly, at the upper end of the coupling sleeve 124, at least one (preferably a plurality of) coupling sleeve anti-rotation teeth 124D are configured which extend in the axial direction. Circumferential rotational movement of the adapter sleeve 124 relative to the adapter 122 is limited by insertion of the adapter sleeve anti-rotation teeth 124D into the adapter anti-rotation slots 122D.
It should be understood that the connecting sleeve 124 may be constructed as one piece or may be formed from multiple sleeve pieces connected together.
In a preferred embodiment, a plurality of fixing block receiving grooves 124B spaced apart from each other are uniformly distributed in the circumferential direction of the connection joint 122, and a plurality of connection sleeve fixing blocks 123 are correspondingly provided.
In an alternative embodiment, the mounting block receiving slots 124B on the inside of the adapter sleeve 124 match the shape of the adapter sleeve mounting block 123 to limit movement of the adapter sleeve mounting block 123 in both the axial and circumferential directions. Therefore, the arrangement of the connecting sleeve anti-rotation teeth 124D and the connecting joint anti-rotation grooves 122D can be omitted, so that the structure is simpler. However, the embodiment in which the fixing block receiving groove 124B is an annular groove is more preferable from the viewpoint of processing.
As shown in fig. 2 and 3, a threaded member receiving hole penetrating the coupling sleeve 124 in a radial direction is configured at a lower end of the coupling sleeve 124. Within which is disposed a first threaded member 129. The outer side wall of the first threaded member 129 is configured with a fourth threaded portion 129C for engagement with a third threaded portion 210C (described in detail below) on the tieback barrel of the liner hanger 200.
A support sleeve 128 is also nested between the mandrel 110 and the connecting sleeve 124. The support sleeve 128 is connected to the connecting sleeve 124 by shear pins 127. In the initial state, the outer sidewall of the body of the support sleeve 128 abuts the inner sidewall of the first threaded member 129 such that the first threaded member 129 is retained within the threaded member receiving bore and the fourth threaded portion 129C thereon projects radially outwardly into engagement with the third threaded portion 210C on the tieback barrel. In addition, the support sleeve 128 is configured with a reduced outer diameter section 128C that underlies the main body of the support sleeve 128. When the support sleeve 128 is moved axially upwardly relative to the coupling sleeve 124, the reduced outer diameter portion 128C opposes the first threaded member 129, allowing the first threaded member 129 to move radially inwardly and the fourth threaded portion 129C to retract radially inwardly to a condition in which it can no longer engage the third threaded portion 210C on the tie-back barrel.
In addition, the attachment mechanism 120 includes a landing sleeve 125 fixedly attached (e.g., by threads) to the exterior of the extension sleeve 126. The landing sleeve 125 is located axially between the connection joint 122 and the support sleeve 128. Hereinafter, the function of the hitching sleeve 125 will be described in detail with reference to the description of the working process.
As shown in fig. 2 and 3, the sitting drive mechanism 130 includes a piston cylinder 133 fixedly connected to the outside of the spindle 110, and a piston cavity is formed between the piston cylinder 133 and the spindle 110. Disposed within the piston cylinder 133 is a piston sleeve 132, the piston sleeve 132 extending upwardly beyond the piston cylinder 133 and fixedly attached (e.g., by threads) to the extension sleeve 126. The piston sleeve 132 is connected to the mandrel 110 by shear pins 131. And piston sleeve 132 is in sealed sliding engagement with piston cylinder 133. Corresponding fluid passages are configured in the mandrel such that fluid in the mandrel 110 can pass through the fluid passages into the piston cylinder 133 to force the piston sleeve 132 axially downward.
As also shown in FIG. 2, the release mechanism 140 includes an inverted nut 141 that fits over the outside of the mandrel 110, with a second threaded portion 141F configured on the outside wall of the inverted nut 141 for engaging a first threaded portion 220F (described in detail below) on the hanger body of the liner hanger 200.
It should be understood that the second threaded portion 141F may be provided in other forms.
FIG. 4 schematically illustrates one embodiment of a liner hanger 200. The liner hanger 200 includes a cylindrical hanger body 220. The hanger body 220 is configured with a first threaded portion 220F on the inside thereof for engagement with the second threaded portion 141F described above.
In addition, the liner hanger 200 further comprises a tie-back cylinder 210, a hanger connecting sleeve 230, an anti-withdrawal sleeve 240 and a taper sleeve 250 which are sequentially sleeved outside the hanger body 220 from top to bottom. Which are fixedly coupled to each other (e.g., via threads) and are axially movable relative to the hanger body 220. It should be understood that all or a part of them may be constructed as one body, as necessary.
The tieback cylinder 210 extends axially upwardly and is configured with a third threaded portion 210C on the inside of its upper end for engagement with a fourth threaded portion 129C on the first threaded member 129.
A hanger stopper hole 230G penetrating the hanger connection sleeve 230 in a radial direction is formed on a sidewall of the hanger connection sleeve 230. A hanger rotation preventing block 290 is provided in the hanger stopper hole 230G. The shape of the hanger anti-rotation block 290 matches the shape of the hanger limiting hole 230G to limit axial and circumferential movement of the hanger anti-rotation block 290 relative to the hanger connection sleeve 230. A corresponding hanger anti-rotation slot 220G is formed on the outer sidewall of the hanger body 220. The hanger anti-rotation block 290 can extend radially inward into the hanger anti-rotation slot 220G. The hanger anti-rotation slots 220G extend in the axial direction and are shape-matched to the hanger anti-rotation blocks 290 to limit circumferential movement of the hanger anti-rotation blocks 290 relative to the hanger body 220 and to allow the hanger anti-rotation blocks 290 to move axially within a range relative to the hanger body 220. A cover plate is covered on the outside of the hanger connection sleeve 230, and the cover plate and the hanger body 220 are respectively clamped on the inner side and the outer side of the hanger rotation preventing block 290 to limit the movement of the hanger rotation preventing block 290 in the radial direction.
Preferably, a plurality of hanger stopper holes 230G spaced apart from each other may be provided along the circumference of the hanger connecting sleeve 230, and a plurality of hanger anti-rotation blocks 290 and hanger anti-rotation grooves 220G may be provided accordingly.
In an alternative embodiment, the hanger restraint hole 230G may be configured as a blind hole. Thus, the cover plate can be omitted.
The inner side of the anti-retreat sleeve 240 is provided with an anti-retreat member 241 (e.g., an anti-retreat clip) for engaging with the hanger body 220. Thus, the anti-back sleeve 240, and the tieback cylinder 210, the hanger connection sleeve 230, and the cone sleeve 250 fixedly connected thereto, can only move axially downward and not axially upward.
The outer side surface of the lower end of the taper sleeve 250 forms an inclined surface 251. A slip coupling sleeve 270 and slips 260 are also sleeved outside the hanger body 220. The slip coupling sleeve 270 is connected to the hanger body 220 by a hanger shear pin 280. The slip coupling sleeve 270 is disposed below the cone 250 in an axially spaced relationship from the cone 250. The slips 260 are located between the cone sleeve 250 and the slip connection sleeve 270, with their lower ends hinged to the upper end of the slip connection sleeve 270, which is configured as a free end. As the cones 250 move relative to the slips 260 toward each other, the slips 260 can move up the inclined surface 251 of the cones 250 and along the inclined surface 251. The slips 260 are thereby caused to move radially outward and effect a ride on the borehole wall.
In the embodiments described above, the first, second, third and fourth threaded portions 220F, 141F, 210C, 129C have the same handedness (e.g., left hand), while all remaining connecting threads that are not intended to be loosened during the release process have the opposite handedness (e.g., right hand).
In the above, the first embodiment of the hanger assembly 1000 in the initial state has been mainly described. In this initial condition, the tieback cylinder, hanger connection sleeve 230, anti-back sleeve 240 and cone 250 are prevented from downward movement relative to hanger body 220 during tailpipe running by the securement of the connection sub 122 and connection sleeve 124 relative to the mandrel 110 and the engagement of the third threaded portion 210C with the fourth threaded portion 129C (preferably also including the mating of the anti-back sleeve 240). Thus, early setting of the liner hanger 200 can be avoided to the maximum extent.
Additionally, even if the liner hanger 200 is set ahead in the extreme downhole conditions, the hanger shear pin 280 may be sheared by lifting the running tool 100, thereby unlocking the hanger to retrieve the entire liner hanger assembly 1000 to the surface.
The normal sitting and hanging process of the tailpipe suspension assembly 1000 described above is as follows. Fluid is forced through the fluid passage into the piston cavity of the piston cylinder 133 by building pressure in the well to force the piston sleeve 132 to move axially downward shearing the shear pin 131. The piston sleeve 132 moves downward with the extension sleeve 126 and the landing sleeve 125 fixedly attached to the extension sleeve 126. In one aspect, the extension sleeve 126 moves downward away from the inside of the attachment sleeve mounting block 123. Thereby, the coupling sleeve fixing block 123 can be moved radially inward to disengage the fixing block receiving groove 124B of the coupling sleeve 124, so that the coupling sleeve 124 and the coupling joint 122 can be separated from each other. On the other hand, the landing sleeve 125 can move downward into engagement with the support sleeve 128 and continue to push the support sleeve 128 downward. Thereby, it is possible to move the connection sleeve 124 connected to the support sleeve 128 downward together and further push the tieback cylinder 210, the hanger connection sleeve 230, the withdrawal prevention sleeve 240, and the taper sleeve 250 downward together. The landing is effectively achieved as the slips 260 move radially outward along the inclined surface 251 of the drogue 250.
After normal setting, release and retrieval can be accomplished by rotating the mandrel 110 of the running tool 100. Specifically, by rotating the spindle 110, the first threaded portion 220F of the hanger body 220 can be separated from the second threaded portion 141F of the release mechanism 140. Thereafter, the mandrel 110 is lifted up so that the piston cylinder 133, the piston sleeve 132, the extension sleeve 126, and the setting sleeve 125 move upward together, but the connection sleeve 124 and the support sleeve 128 do not move upward together because they have separated. When the piston cylinder 133 is moved upwardly into engagement with the lower end of the support sleeve 128, the support sleeve 128 may be urged to move upwardly together. At this point, the shear pin 127 shears, and the support sleeve 128 moves upwardly relative to the connecting sleeve 124 to a position where the reduced outer diameter portion 128C opposes the first threaded member 129, allowing the first threaded member 129 to move radially inwardly until the third threaded portion 210C is disengaged from the fourth threaded portion 129C. Thereafter, continued lifting allows retrieval of the running tool 100 or the major components of the running tool 100 including the setting drive mechanism 130 to the surface.
If not properly seated (e.g., due to a failure to hold the pressure in the well, causing the seating drive mechanism 130 to not work properly), the same may be used to effect release and retrieval by rotating the mandrel 110 of the running tool 100. Specifically, if not properly seated, the tailpipe suspension assembly 100 may be configured as shown in fig. 5 such that the third threaded portion 210C remains coupled to the fourth threaded portion 129C, and the connection sub 122 remains coupled to the connection sleeve 124. By rotating the mandrel 110, the first threaded portion 220F can be separated from the second threaded portion 141F. Meanwhile, as shown in fig. 6, as the mandrel 110 rotates, the third thread part 210C of the tieback cylinder 210 and the fourth thread part 129C of the first thread member 129 are unscrewed from each other. This is because the first threaded member 129, the connecting sleeve 124, and the connecting sub 122 can remain circumferentially fixed relative to the mandrel 110, while the tieback barrel 210 can remain circumferentially fixed relative to the hanger body 220. Through this process, the connecting sleeve 124, the connecting sub 122, and the connecting sleeve fixing block 123 are moved upward together by a certain distance with respect to the mandrel 110, and thus moved upward by a certain distance with respect to the extension sleeve 126, so that the extension sleeve 126 is spaced apart from the inside of the connecting sleeve fixing block 123. The coupling sleeve fixing block 123 can be moved radially inward to be separated from the fixing block receiving groove 124B. Thus, the connection sub 122 may be separated relative to the connection sleeve 124. Thereafter, retrieval of the running tool 100, or major components of the running tool 100 including the setting drive mechanism 130, to the surface may be accomplished by lifting the mandrel 110 upward.
That is, regardless of whether the setting is successful, the operator can effect the release and retrieval of the running tool 100 by a simple rotation and lifting action.
Fig. 7-10 show a second embodiment of a tailpipe suspension assembly 1000. The structure of this second embodiment is similar to that of the first embodiment, and thus the description of the first embodiment applies to the second embodiment if not explicitly stated or if there is a conflict. The structural differences between the first embodiment and the second embodiment are as follows.
As shown in fig. 7, a joint stopper hole penetrating the connection joint 122 in a radial direction is formed at a lower end of the connection joint 122. A second threaded member 123' is disposed within the joint retaining bore. The outer side wall of the second screw member 123' is configured with a sixth screw portion 123H. A fifth threaded portion 124H is configured on the inside of the upper end of the connecting sleeve 124. In the initial state, the second threaded member 123' is radially sandwiched between the extension sleeve 126 and the connection sleeve 124. At this time, the fifth screw portion 124H is engaged with the sixth screw portion 123H.
In addition, the adapter rotation-preventing grooves 122D and the adapter rotation-preventing teeth 124D do not need to be provided on the adapter 122 and the adapter 124.
Furthermore, a fixing block receiving hole 124I penetrating the coupling sleeve 124 in the radial direction is configured at the lower end of the coupling sleeve 124. Disposed within the mounting block receiving bore 124I is a tieback cartridge mounting block 129'. Accordingly, as shown in fig. 8, a fixing block receiving groove 210I is configured at an upper end inner side of the tieback cylinder 201. The mounting block receiving aperture 124I matches the shape of the tieback mount block 129 'to limit circumferential and axial movement of the tieback mount block 129'. Additionally, the fixing block receiving slot 210I may be configured as an annular groove that matches the shape of the tieback cartridge fixing block 129 'to limit axial movement of the tieback cartridge fixing block 129'. Correspondingly, at the lower end of the connecting sleeve 124, at least one (preferably a plurality of) hanger anti-rotation slots 124J extending in the longitudinal direction are configured; at least one (and preferably a plurality of) hanger anti-rotation teeth extending in the longitudinal direction are configured at the upper end of the tieback barrel 210. Relative rotation of the take-back cylinder 210 and the adapter sleeve 124 is limited by the engagement of the hanger anti-rotation slots 124J and the hanger anti-rotation teeth.
In the initial state, the main body of the support sleeve 128 is inside the tiebar fixing block 129 'so that the tiebar fixing block 129' can extend radially outward into the fixing block receiving groove 210I of the tiebar 210. When the support sleeve 128 moves upward relative to the connecting sleeve 124, the reduced outer diameter portion 128I of the support sleeve 128 opposes the tie-back cartridge securing block 129 'to allow the tie-back cartridge securing block 129' to move radially inward out of the securing block receiving slot 210I.
Alternatively, the fixing block receiving slot 210I may be configured to match the shape of the tieback cartridge fixing block 129 'to limit axial and circumferential movement of the tieback cartridge fixing block 129'. In this case, the hanger anti-rotation slots 124J and the hanger anti-rotation teeth may be omitted.
The first threaded member 129 and the tieback cartridge mount block 129 'and the connecting sleeve mount block 123 and the second threaded member 123' are not significantly different in function in the initial state and the normal set, released state, and the descriptions thereof may correspond to each other without being contradicted.
In the abnormal sitting and hanging state, the second embodiment can realize releasing only by rotating the mandrel 110 by the operator, however, the matching relation among the components is changed. Specifically, by rotating the mandrel 110, the first threaded portion 220F can be separated from the second threaded portion 141F. Meanwhile, as shown in fig. 9, as the mandrel 110 rotates, the fifth screw part 124H of the connection sleeve 124 and the sixth screw part 123H of the second screw member 123' are unscrewed from each other. This is because the second threaded member 123' and the connection nipple 122 can remain circumferentially fixed relative to the mandrel 110, while the tieback cartridge 210 and the connection sleeve 124 can remain circumferentially fixed relative to the hanger body 220. Through this process, the connection nipple 122 and the second threaded member 123 'together move a distance upward relative to the mandrel 110 and thus a distance upward relative to the extension sleeve 126 such that the extension sleeve 126 is clear of the inside of the second threaded member 123'. The second screw member 123' can be moved radially inward until the fifth screw portion 124H is separated from the sixth screw portion 123H. Thus, the connection sub 122 may be separated relative to the connection sleeve 124. At this time, however, the tieback cartridge mounting block 129' is still in the mounting block receiving slot 210I.
Thereafter, as shown in fig. 10, the mandrel 110 may be lifted up such that the piston cylinder 133 moves upward together, but the connecting sleeve 124 and the support sleeve 128 do not follow upward together as they have separated. When the piston cylinder 133 is moved upwardly into engagement with the lower end of the support sleeve 128, the support sleeve 128 may be urged to move upwardly together. At this point, the shear pins 127 shear and the support sleeve 128 moves upwardly relative to the connecting sleeve 124 to a position where the reduced outer diameter portion 128I is opposite the tiebar mounting block 129 ', allowing the tiebar mounting block 129' to move radially inwardly out of engagement with the mounting block receiving slots 210I. Thereafter, continued lifting allows retrieval of the running tool 100 or the major components of the running tool 100 including the setting drive mechanism 130 to the surface.
While the invention has been described with reference to a preferred embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In particular, the technical features mentioned in the embodiments can be combined in any way as long as there is no structural conflict. It is intended that the invention not be limited to the particular embodiments disclosed, but that the invention will include all embodiments falling within the scope of the appended claims.
