Description

Technical Field

[0001] This application relates to the field of oilfield engineering machinery technology, and in particular to a tower. Background Technology

[0002] In the oil extraction process, the injection head of the tubing string is usually installed in the skid at the top of the injection head tower. The continuous tubing connected to the injection head can pass through the injection head tower and extend into the oil well under the guidance of the injection head.

[0003] However, in related technologies, the height of the injection head tower is relatively fixed, making it difficult to meet the requirements of different installation heights. Utility Model Content

[0004] In view of this, the main objective of the embodiments of this application is to provide a tower that can better achieve height adjustment.

[0005] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0006] This application provides a tower, including:

[0007] Multiple sub-towers are provided, each sub-tower being arranged along a height direction. Each sub-tower includes multiple pry bars that are sequentially slidably connected along the height direction. Along the height direction, each sub-tower has an extended state and a retracted state. The sub-tower slides away from each other via the pry bars to switch to the extended state; the sub-tower slides towards each other via the pry bars to switch to the retracted state.

[0008] In one embodiment, between two adjacent sub-towers, when the bottom sub-tower is in the deployed state, the top sub-tower is connected to the top of the bottom sub-tower.

[0009] In one embodiment, when the sub-tower switches from the deployed state to the retracted state, at least a portion of the top skid slides along the height direction into the enclosed space of the bottom skid between two adjacent skids.

[0010] In one embodiment, when the sub-tower is in the deployed state, among adjacent skids of the same sub-tower, the external dimensions of the top skid are smaller than those of the bottom skid.

[0011] In one embodiment, the tower further includes a base frame, and each of the sub-towers is located on the top side of the base frame, and the sub-towers are slidable relative to the base frame along a first direction; wherein, the first direction is perpendicular to the height direction.

[0012] In one embodiment, the tower further includes a mobile platform, the base frame extends along the first direction, the sub-tower is disposed on the mobile platform, one of the mobile platform and the base frame includes a pulley, and the other includes a slide rail extending along the first direction, the pulley and the slide rail being slidably engaged so that the mobile platform is slidably disposed on the base frame along the first direction.

[0013] In one embodiment, the tower includes a top platform. Among the plurality of sub-towers, the top sub-tower is the top tower. When the top tower is in the deployed state, the top skid in the top tower is the first top skid, and the top platform is disposed on the first top skid.

[0014] In one embodiment, the top platform includes a rotary mechanism for mounting an injection head, at least a portion of which is rotatably mounted on the first top skid.

[0015] In one embodiment, the tower further includes a base frame, each of the sub-towers is located on the top side of the base frame, and the sub-towers are slidable relative to the base frame along a first direction; along a second direction, at least a portion of the top platform is movably mounted on the first top skid; wherein the first direction, the second direction, and the height direction are mutually perpendicular to each other.

[0016] In one embodiment, between two adjacent sub-towers, in the top sub-tower, the bottom skid is a first bottom skid, and in the bottom sub-tower, the top skid is a second top skid. The first bottom skid is disposed on the top side of the second top skid, and the outer dimensions of the first bottom skid are larger than those of the second top skid.

[0017] This application provides a tower frame including multiple sub-towers, each arranged along the height direction. Each sub-tower includes multiple skids slidably connected sequentially along the height direction. Along the height direction, the sub-towers slide away from each other via the skids to switch to an extended state. Conversely, the sub-towers slide closer together via the skids to switch to a retracted state. Therefore, by stacking multiple sub-towers along the height direction, the overall height of the tower frame can be increased. Furthermore, since each sub-tower includes multiple skids, and each skid can slide along the height direction, each sub-tower can extend and retract along the height direction. Thus, the overall height of the tower frame can be adjusted by sliding the skids of each sub-tower, thereby achieving better height adjustment of the tower frame. Attached Figure Description

Figure 1 The orientation or positional relationship shown, the "second direction" orientation or positional relationship is based on the attached... Figure 2 The orientation or positional relationship shown is for illustrative purposes only and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0023] One embodiment of this application provides a tower; please refer to [link / reference]. Figure 1 and Figure 2 The tower includes multiple sub-towers 10.

[0024] Each sub-tower 10 is arranged along the height direction, and each sub-tower 10 includes a plurality of skids 11 that are slidably connected along the height direction. Along the height direction, the sub-tower 10 has an extended state and a retracted state. The sub-tower 10 is switched to the extended state by sliding the skids 11 in a direction away from each other. The sub-tower 10 is switched to the retracted state by sliding the skids 11 in a direction closer to each other by sliding the skids 11.

[0025] Each sub-tower 10 is arranged along the height direction. Between two adjacent sub-towers 10, when the bottom sub-tower 10 is in the unfolded state, the top sub-tower 10 is connected to the top of the bottom sub-tower 10.

[0026] Specifically, the tower in this application embodiment can be any type of tower. For ease of description, this application embodiment is described using a tower used in conjunction with a pipe string as an example.

[0027] The tower includes multiple sub-towers 10, the specific number of which is unlimited, and each sub-tower 10 is arranged along the height direction. This allows for an extension of the tower's height to accommodate the installation requirements of taller towers.

[0028] Each sub-tower 10 includes multiple skids 11. It should be noted that, depending on the actual situation, the number of skids 11 included in each sub-tower 10 may be the same or different. Furthermore, the specific structure of each sub-tower 10 may be the same or different.

[0029] In each sub-tower 10, each skid 11 is arranged along the height direction, and adjacent skids 11 can slide relative to each other along the height direction. Therefore, by adjusting the relative position between each skid 11, the height of each sub-tower 10 can be adjusted, thereby adjusting the overall height of the tower, thus meeting the actual installation requirements.

[0030] Each sub-tower 10 has both an extended state and a retracted state.

[0031] In the deployed state, adjacent pry bars 11 are connected at a distance from each other, thus maximizing the height of the sub-tower 10. In the retracted state, adjacent pry bars 11 are connected at a close proximity, thus minimizing the height of the sub-tower 10. By sliding the pry bars 11 together, the sub-tower 10 can switch between the deployed and retracted states.

[0032] It should be noted that, depending on actual needs, the sub-tower 10 can also slide only the pry bar 11 to allow the sub-tower 10 to be in an intermediate state between the unfolded state and the retracted state. At this time, the height of the sub-tower 10 is between the height in the unfolded state and the height in the retracted state.

[0033] For each sub-tower 10, the connection method between adjacent sub-towers 10 can be set according to the actual situation. It can be a fixed connection, a sliding connection, or a detachable connection.

[0034] Each sub-tower 10 is set along the height direction, but the specific connection position between adjacent sub-towers 10 can be set according to the actual situation.

[0035] For example, between two adjacent sub-towers 10, when the bottom sub-tower 10 is in the deployed state, the top sub-tower 10 is connected to the top of the bottom sub-tower 10. That is, in two adjacent sub-towers 10, the top sub-tower 10 is connected to the topmost skid 11 of the bottom sub-tower 10. This allows the overall height of the tower in the deployed state to be as high as possible, making the tower more adaptable.

[0036] In the tower of this application, the sub-tower 10 slides away from each other via each skid 11, thereby switching the sub-tower 10 to an extended state. The sub-tower 10 also slides towards each other via each skid 11, thereby switching the sub-tower 10 to a retracted state. Thus, by stacking multiple sub-towers 10 along the height direction, the overall height of the tower can be increased. Furthermore, since each sub-tower 10 includes multiple skids 11, and each skid 11 can slide along the height direction, each sub-tower 10 can extend and retract along the height direction. Therefore, the overall height of the tower can be adjusted by sliding the skids 11 of each sub-tower 10, thereby achieving better height adjustment of the tower.

[0037] In one embodiment, when the sub-tower 10 switches from an unfolded state to a retracted state, at least a portion of the top skid 11 slides along the height direction into the enclosed space of the bottom skid 11 between two adjacent skids 11. This significantly reduces the overall volume of the sub-tower 10 in the retracted state.

[0038] Specifically, the skid 11 forms an enclosed space in the middle by enclosing. When switched to the storage state, the top skid 11 of the adjacent skids 11 can be stored in the enclosed space of the bottom skid 11, so that the skids 11 of the sub-tower 10 overlap together, making the overall volume of the sub-tower 10 smaller.

[0039] It should be noted that, depending on the actual situation, a portion of the top pry bar 11 may be housed within the enclosed space of the bottom pry bar 11, or the entire top pry bar 11 may be housed within the enclosed space of the bottom pry bar 11.

[0040] In one embodiment, please refer to Figure 1 and Figure 2 When the sub-tower 10 is in the deployed state, among the adjacent skids 11 of the same sub-tower 10, the outer dimensions of the top skid 11 are smaller than those of the bottom skid 11. This makes it easier for the top skid 11 to be stored in the bottom skid 11, while also improving the overall stability of the sub-tower 10.

[0041] In one embodiment, please refer to Figure 1 and Figure 2 The tower also includes a base frame 20, and each sub-tower 10 is located on the top side of the base frame 20. The sub-tower 10 can slide relative to the base frame 20 along a first direction, which is perpendicular to the height direction. This allows for easy movement of each sub-tower 10 along the first direction, effectively adjusting the horizontal position of the sub-tower 10 along that direction.

[0042] Specifically, the sub-towers 10 are arranged along the height direction, and the bottom sub-tower 10 is slidably mounted on the base frame 20 and can slide along the first direction. Thus, by moving the bottom sub-tower 10, the sub-towers 10 above it can be moved along the first direction, thereby adjusting the horizontal position of each sub-tower 10 along the first direction.

[0043] It should be noted that the specific sliding connection method between the sub-tower 10 and the base frame 20 is not limited.

[0044] For example, please see Figure 1 and Figure 2 The tower also includes a movable platform 30, a base frame 20 extending along a first direction, and a sub-tower 10 mounted on the movable platform 30. One of the movable platform 30 and the base frame 20 includes a pulley, and the other includes a slide rail extending along the first direction. The pulley and slide rail are slidably engaged, allowing the movable platform 30 to be slidably mounted on the base frame 20 along the first direction. This allows the sub-tower 10 to be oriented and moved along the first direction, facilitating adjustment of its position along that direction.

[0045] Specifically, the sub-tower 10 is fixedly mounted on the mobile platform 30, and the movement of each sub-tower 10 along the first direction is achieved through the relative sliding between the mobile platform 30 and the base frame 20.

[0046] The mobile platform 30 and the base frame 20 are connected by pulleys and slide rails to achieve a sliding connection.

[0047] Depending on the actual situation, for example, the bottom of the mobile platform 30 may be equipped with pulleys, and the top of the base frame 20 may be equipped with a slide rail extending in the first direction. Thus, the sub-tower 10 and the mobile platform 30 can slide along the slide rail via pulleys, thereby realizing the position adjustment of the sub-tower 10.

[0048] Alternatively, the bottom of the mobile platform 30 can be equipped with a slide rail, and the top of the base frame 20 can be equipped with a pulley.

[0049] In one specific embodiment, the bottom of the mobile platform 30 includes two sets of pulleys, which are spaced apart along a second direction. The top of the base frame 20 includes two sets of slide rails, which are spaced apart along a second direction and extend along a first direction. The two sets of pulleys are slidably connected to the two sets of slide rails one-to-one, so that the sub-tower 10 can slide along the first direction. The second direction is perpendicular to the first direction and the height direction.

[0050] In one embodiment, please refer to Figure 1 and Figure 2The tower includes a top platform 40. Among the multiple sub-towers 10, the top sub-tower 10 is the top tower 12. When the top tower 12 is in the deployed state, the top skid 11 in the top tower 12 is the first top skid 111, and the top platform 40 is set on the first top skid 111.

[0051] The top platform 40 is used to install the injection head. By mounting the top platform 40 on the topmost skid 11, the height of the top platform 40 can be maximized, thereby increasing the height adjustment range of the top platform 40.

[0052] In one embodiment, the top platform 40 includes a rotary mechanism for mounting an injection head, at least a portion of which is rotatably mounted on a first top skid 111.

[0053] Therefore, by setting up a rotary mechanism, the injection head can be rotated within a certain angle range. This allows the operating angle of the injection head to be adjusted when the injection head guides the coiled tubing into the oil well, thereby expanding the operating range of the injection head to adapt to different oil wells.

[0054] In one embodiment, the tower also includes a base frame 20, each sub-tower 10 is located on the top side of the base frame 20, and the sub-tower 10 can slide relative to the base frame 20 along a first direction; along a second direction, at least a portion of the top platform 40 is movably disposed on the first top skid 111; wherein the first direction, the second direction and the height direction are perpendicular to each other.

[0055] Therefore, by sliding the sub-tower 10 along the first direction, the positions of the sub-tower 10 and the top platform 40 along the first direction can be adjusted, and by moving the top platform 40 along the second direction, the position of the top platform 40 along the second direction can be adjusted. Thus, the position of the top platform 40 can be adjusted in multiple directions, facilitating the adjustment of the injection head's operating angle.

[0056] In one embodiment, please refer to Figure 1 and Figure 2 Between two adjacent sub-towers 10, in the top sub-tower 10, the bottom skid 11 is the first bottom skid 112, and in the bottom sub-tower 10, the top skid 11 is the second top skid 113. The first bottom skid 112 is located on the top side of the second top skid 113, and the outer dimensions of the first bottom skid 112 are larger than the outer dimensions of the second top skid 113.

[0057] In other words, between two adjacent sub-towers 10, the size of the bottom skid 11 of the top sub-tower 10 is larger than the size of the top skid 11 of the bottom sub-tower 10. This avoids the skid 11 at the top of the tower being too small, thus preventing a reduction in the overall strength of the tower.

[0058] In one specific embodiment, the base frame 20 has a length of 20m along the first direction. The tower includes a first sub-tower 10 and a second sub-tower 10, with the first sub-tower 10 located on top of the second sub-tower 10. The first sub-tower 10 includes two relatively slidable skids 11, and the second sub-tower 10 includes four relatively slidable skids 11. When the first sub-tower 10 is in the deployed state, its working height is 3.8m. When the second sub-tower 10 is in the deployed state, its working height is 9m.
