Description

Technical Field

[0001] The utility model relates to the technical field of workover operations, and particularly to a strong magnetic adsorption type drift gauge. Background Art

[0002] During operations such as sidetracking and shallow drilling, when casing is run in, generally a drift is required to detect whether the casing is deformed, which is a necessary technical means to ensure that the casing meets the downhole requirements. In the traditional use of casing, a cylinder made of wire rope and engineering plastic that meets the requirements of the inner diameter of the casing is generally used for drifting. The operation method is to pull the cylinder back and forth with a wire rope. The operator spends a lot of time and effort, has low efficiency, and there are potential safety hazards of injury.

[0003] In order to reduce potential safety hazards and improve the drifting efficiency. Currently, an electric intelligent drift gauge (the specific structure can refer to Chinese invention patent: CN106761694A) is used to replace the traditional drifting method. However, there is a phenomenon that the driving wheel slips on the inner wall of the casing when the electric intelligent drift gauge is drifting. When the driving wheel slips, it is easy to cause the electric intelligent drift gauge to fail to move forward normally, which will affect the drifting efficiency and increase the failure rate of drifting.

[0004] That is to say, in the prior art, there is a problem that the driving wheel of the electric intelligent drift gauge slips on the inner wall of the casing. Summary of the Utility Model

[0005] The utility model provides a strong magnetic adsorption type drift gauge for solving the problem that the driving wheel slips on the inner wall of the casing.

[0007] A body assembly for drifting; and

[0019] In one embodiment, a control module is further included, which is arranged in the body assembly and is electrically connected to the driving motor and the speed reduction mechanism for controlling the driving motor and the speed reduction mechanism to work.

[0020] In one embodiment, a plurality of centering wheels are further included, and the plurality of centering wheels are rotatably arranged on the outer periphery of the body assembly for centering the strong magnetic adsorption type full-bore gauge.

[0021] In one embodiment, the body assembly includes:

[0031] In one embodiment, it further includes a lifting lug, which is connected to the sliding sleeve assembly and is used for lifting the strong magnetic adsorption type drift gauge.

[0032] In one embodiment, it further includes a handle, which is arranged on the support frame.

[0033] Compared with the prior art, the advantages of the present utility model are that since the strong magnetic adsorption wheel assembly can adsorb on the inner wall of the casing and is closely attached to the inner wall of the casing under the action of magnetic force.

[0041] The present utility model will be further described below in conjunction with the accompanying drawings.

[0042] As Figure 1 and Figure 2 shown, the present utility model provides a strong magnetic adsorption type caliber gauge. The strong magnetic adsorption type caliber gauge includes a body assembly 10, a strong magnetic adsorption wheel assembly 20 and a drive assembly 30. Among them, the body assembly 10 is used for sizing; the strong magnetic adsorption wheel assembly 20 can be adsorbed inside the inner wall of the casing and can roll inside the inner wall of the casing; the drive assembly 30 is connected to the strong magnetic adsorption wheel assembly 20, and the drive assembly 30 is arranged on the body assembly 10 for driving the strong magnetic adsorption wheel assembly 20 to roll inside the inner wall of the casing.

[0043] In the above setting, since the strong magnetic adsorption wheel assembly 20 can be adsorbed inside the inner wall of the casing and is closely attached to the inner wall of the casing under the action of magnetic force. In this way, when the drive assembly 30 drives the strong magnetic adsorption wheel assembly 20 to rotate, the strong magnetic adsorption wheel assembly 20 will not slip inside the inner wall of the casing. Thereby ensuring that the strong magnetic adsorption type caliber gauge can stably move along the inner wall surface of the casing for sizing. Furthermore, the drive sizing ability of the strong magnetic adsorption type caliber gauge is enhanced. In this way, the problem that the strong magnetic adsorption type caliber gauge cannot work properly caused by the driving wheel slipping inside the inner wall of the casing in the prior art is avoided.

[0044] Specifically, as Figure 1 and Figure 4As shown, in one embodiment, the strong magnetic adsorption wheel assembly 20 includes a strong magnetic connection wheel 21 and a strong magnetic adsorption wheel 22. Among them, the strong magnetic connection wheel 21 is connected to the drive assembly 30; the strong magnetic adsorption wheel 22 is arranged on the outer periphery of the strong magnetic connection wheel 21; the strong magnetic adsorption wheel 22 can roll inside the inner wall of the casing. The structure of the strong magnetic adsorption wheel 22 is that a strong magnetic material is inlaid inside and the outer edge is a metal round wheel. According to the principle that strong magnetism can magnetize metal, the strong magnetic adsorption wheel 22 can adsorb on the inner wall of the casing to achieve the adsorption function.

[0045] Specifically, as Figure 1 and Figure 4 shown, in one embodiment, the drive assembly 30 includes a drive motor 31 and a speed reduction mechanism 32. Among them, the drive motor 31 is fixed on the body assembly 10; the speed reduction mechanism 32, its input end is connected to the drive shaft of the drive motor 31, and the output end of the speed reduction mechanism 32 is connected to the strong magnetic adsorption wheel assembly 20; the drive motor 31 is used to drive the speed reduction mechanism 32 to act to transmit torque to the strong magnetic adsorption wheel assembly 20.

[0046] In the above setting, setting the speed reduction mechanism 32 can reduce the rotation speed of the strong magnetic adsorption wheel assembly 20 and increase the torque of the strong magnetic adsorption wheel assembly 20 at the same time. In this way, while preventing the strong magnetic adsorption wheel assembly 20 from slipping, it can ensure that the strong magnetic adsorption wheel assembly 20 overcomes the adsorption force to rotate normally inside the inner wall of the casing. Thus, it is ensured that the strong magnetic adsorption type full-bore gauge can perform full-bore measurement normally.

[0047] Specifically, as Figure 1 shown, in one embodiment, the strong magnetic adsorption type full-bore gauge further includes a battery 40. The battery 40 is arranged inside the body assembly 10 and is electrically connected to the drive motor 31 and the speed reduction mechanism 32 for supplying power to the drive motor 31 and the speed reduction mechanism 32.

[0048] Specifically, as Figure 1 shown, in one embodiment, the strong magnetic adsorption type full-bore gauge further includes a control module 50. It is arranged inside the body assembly 10 and is electrically connected to the drive motor 31 and the speed reduction mechanism 32 for controlling the operation of the drive motor 31 and the speed reduction mechanism 32.

[0049] It should be noted that the control module 50 is a control circuit, which is used to control the actions of the drive motor 31 and the speed reduction mechanism 32. It is a prior art and will not be elaborated here.

[0050] Specifically, as Figure 1 shown, in one embodiment, the strong magnetic adsorption type full-bore gauge further includes a plurality of centralizing wheels 60. The plurality of centralizing wheels 60 are rotatably arranged on the outer periphery of the body assembly 10 for centralizing the strong magnetic adsorption type full-bore gauge.

[0051] Specifically, as Figure 1As shown, in one embodiment, the body component 10 includes a drift body 11, a drift chuck 12, a support frame 13, and a floating support mechanism 14. Among them, the drift chuck 12 is provided at one end of the drift body 11; the support frame 13 is provided at the other end of the drift body 11; the floating support mechanism 14 is provided on the outer periphery of the drift body 11; the drive component 30 is provided on the support frame 13.

[0052] Specifically, as Figure 3 shown, in one embodiment, the floating support mechanism 14 includes a sliding sleeve assembly 141 and a plurality of floating wheel assemblies 142. Among them, the sliding sleeve assembly 141 is slidably provided in the drift body 11 along the first direction ( Figure 3 the horizontal direction); a plurality of floating wheel assemblies 142 are circumferentially spaced on the drift body 11; the floating support mechanism 14 is configured such that when the sliding sleeve assembly 141 slides away from the body component 10 to the first sliding position, the plurality of floating wheel assemblies 142 contract, and when the sliding sleeve assembly 141 slides toward the body component 10 to the second sliding position, the plurality of floating wheel assemblies 142 expand.

[0053] Specifically, as Figure 1 shown, in one embodiment, the strong magnetic adsorption type drift also includes a lifting lug 70, and the lifting lug 70 is connected to the sliding sleeve assembly 141 for lifting the strong magnetic adsorption type drift. This facilitates the overall lifting of the strong magnetic adsorption type drift.

[0054] Specifically, as Figure 1 shown, in one embodiment, the strong magnetic adsorption type drift also includes a handle 80, and the handle 80 is provided on the support frame 13.

[0055] Next, in combination with Figures 1 to 4 describe a specific embodiment of the present application:

[0056] The present utility model provides a strong magnetic adsorption type drift, which mainly includes a drift body 11, a floating support wheel 1422, a drift chuck 12, a tail rope loop (lifting lug 70), a control module housing 111, a battery module housing 112, a drive module housing 113, a charging port 114 (for charging the battery 40), a drive motor 31, a strong magnetic adsorption wheel 22, a handle 80, a transmission belt cover 90, a reduction mechanism 32, a centering wheel 60, a switch 100 (manual control switch for controlling the circuit connection of the strong magnetic adsorption type drift), a power display lamp 120 (displaying whether the circuit of the strong magnetic adsorption type drift is connected), a sliding sleeve shaft 1411, a sliding sleeve 1412, a support seat 1421, a reduction box shaft 321, a reduction box wheel 322, a conveyor belt 323, an adsorption wheel shaft 23, and a strong magnetic connection wheel 21.

[0057] It should be noted that the handle 80 is convenient for human hands to hold, facilitating the on-site staff to move the strong magnetic adsorption type drift gauge. The centralizer wheel 60 contacts with the inner wall of the casing to centralize the strong magnetic adsorption type drift gauge. The centralizing principle of the centralizer wheel 60 can refer to the centralizing principle of centralizers in the petroleum field.

[0058] Specifically, the control module housing 111, the battery module housing 112 and the drive module housing 113 are configured to form the drift gauge body 11. The drift gauge chuck 12 is arranged at one end of the drift gauge body 11. The charging port 114 is arranged at the other end of the drift gauge body 11. A battery 40 is arranged in the battery module housing 112, a drive module 110 is arranged in the drive module housing 113, and a control module 50 is arranged in the control module housing 111.

[0059] It should be noted that the drive module 110 is electrically connected to the drive motor 31 and the reduction mechanism 32, and is used to drive the drive motor 31 and the reduction mechanism 32 to act. The control module 50 is electrically connected to the drive module 110, and controls the drive motor 31 and the reduction mechanism 32 to act by controlling the drive module 110.

[0060] Specifically, the reduction mechanism 32 includes a reduction gearbox shaft 321, a reduction gearbox wheel 322 and a conveyor belt 323. The reduction gearbox wheel 322 is the reducer, which is a prior art and will not be elaborated here. The reduction gearbox shaft 321 is the output end of the reducer, and transmits the torque to the adsorption wheel shaft 23 through the reduction gearbox wheel 322 and the conveyor belt 323. A conveyor belt cover 90 is arranged outside the conveyor belt 323.

[0061] Specifically, the sliding sleeve assembly 141 includes a sliding sleeve shaft 1411 and a sliding sleeve 1412.

[0062] It should be noted that the sliding sleeve shaft 1411 is slidably connected to the sliding sleeve 1412. The sliding sleeve shaft 1411 is fixed on the drift gauge chuck 12. A spring 1413 is sleeved on the sliding sleeve shaft 1411 and is located between the sliding sleeve shaft 1411 and the sliding sleeve 1412. In the initial state (refer to Figure 3 ), the spring 1413 applies a pressing force to the sliding sleeve 1412, so that the sliding sleeve 1412 presses the limit switch 130 below it. At this time, the limit switch 130 is in the off state, and the control module 50, the drive module 110, the drive motor 31 and the reduction mechanism 32 are disconnected and no circuit is formed, and the control module 50, the drive module 110, the drive motor 31 and the reduction mechanism 32 cannot work properly.

[0063] It should be noted that the limit switch 130 is used to control the conduction between the control module 50, the drive module 110, the drive motor 31 and the reduction mechanism 32.

[0064] Specifically, the floating wheel assembly 142 includes a support base 1421 and a floating support wheel 1422.

[0065] It should be noted that the floating support wheel 1422 is hinged to the support base 1421. The support base 1421 is fixed on the full-bore gauge chuck 12. One end of the floating support wheel 1422 is clamped inside the sliding sleeve 1412. When the strong magnetic adsorption type full-bore gauge enters the casing, the other end of the floating support wheel 1422 contacts the inner wall of the casing, and the floating support wheel 1422 contracts. One end of it drives the sliding sleeve 1412 to move upward. The sliding sleeve 1412 moves away from the limit switch 130. When it does not contact the limit switch 130, the limit switch 130 is in a closed state at this time, and a path is formed among the control module 50, the drive module 110, the drive motor 31 and the reduction mechanism 32, and the control module 50, the drive module 110, the drive motor 31 and the reduction mechanism 32 can work normally.

[0066] Compared with the prior art, the present utility model has the following advantages:

[0067] The device optimizes the structure of the strong magnetic adsorption wheel, adds the structure for strongly magnetically adsorbing the casing wall, and adds a reduction mechanism device, so that the full-bore gauge has anti-slip ability and enhances the full-bore ability of the entire full-bore gauge.

[0068] This device mainly consists of a strong magnetic drive wheel, an electric control drive system and a battery. The battery can be used as power to drive the strong magnetic drive wheel to rotate through the reduction mechanism, automatically pass through the pipe in the casing, reduce manual operation, save time and effort, and is safe and reliable. It has significant economic and social benefits as well as good use effects and application values.

[0069] Although the present utility model has been described with reference to the preferred embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way.
