Abstract
Description
Technical Field
[0001] This utility model relates to the field of rotary guide devices, and in particular to a rotary guide rotation vibration testing fixture. Background Technology
[0002] Logging while drilling (LoWW) technology allows for the measurement and recording of geological and engineering data underground while drilling is in progress. This technology provides real-time information on formation lithology, porosity, permeability, and reservoir characteristics, helping engineers optimize drilling paths and improve the efficiency and success rate of oil and gas field development. Rotary guides play a crucial role in LoWW, significantly improving the efficiency and safety of drilling operations by measuring formation information in real time and adjusting the drilling direction.
[0003] In logging-while-drilling (LoWL) technology, rotary guides, used in drilling operations, require rotational motion and are subject to vibration forces generated during vibratory drilling. These forces can interfere with the precise guiding function of the rotary guide and may even damage critical components. Therefore, quality testing is necessary during the production and processing of rotary guides.
[0004] Existing testing methods for rotary drilling rigs mostly utilize tooling adapted to the rig to simulate its motion downhole and create the vibration environment it would experience. The aim is to test the rig's response under these conditions, verify its vibration immunity, and thus ensure its reliability in actual drilling. However, most current testing tooling can only sequentially perform vibration and rotation operations on the rig, failing to simultaneously simulate both its motion and vibration environment downhole. This limitation can easily affect the accuracy of the rig testing. Utility Model Content

[0006] To achieve the above objectives, this application provides the following technical solution: a rotary guide vibration testing fixture, comprising a rotary guide device, a positioning structure disposed on the rotary guide device, a vibration table disposed on the positioning structure, and a frame adjacent to the vibration table. The frame is provided with a rotating unit, and the rotating unit is provided with a transmission structure. The transmission structure is connected to one end of the rotary guide device. When the vibration table and the rotating unit operate synchronously, the rotary guide device can be simultaneously in a rotating and vibrating state.
[0007] Furthermore, the positioning structure includes a vibration base plate mounted on the vibration table. The vibration base plate is provided with two symmetrically distributed bearing seat mounting plates. Each bearing seat mounting plate is provided with an outer spherical bearing. The outer spherical bearing is connected to the rotating guide device through a bearing seat adapter ring.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example: Reference Figure 1-4 The rotating vibration testing fixture shown includes a rotating device 6, a positioning structure on the rotating device 6, a vibration table 1 on the positioning structure, and a frame 19 adjacent to the vibration table 1. The frame 19 is provided with a rotating unit, and the rotating unit is provided with a transmission structure. The transmission structure is connected to one end of the rotating device 6. When the vibration table 1 and the rotating unit operate synchronously, the rotating device 6 can be in a state of rotation and vibration at the same time.
[0023] Therefore, the combination of the vibration table 1 and the rotating unit can create a working environment that combines rotation and vibration, thereby simulating the working environment of the rotating guide device 6 with a high degree of simulation. In this environment, comprehensive and efficient testing operations can be performed on the rotating guide device 6, improving the accuracy of the testing operations and thus enabling the assessment of the quality of the rotating guide device 6, thereby improving the accuracy of the assessment operation.
[0024] Specifically, the positioning structure includes a vibration base plate 2 mounted on the vibration table 1. The vibration base plate 2 has two symmetrically distributed bearing seat mounting plates 3, each equipped with an outer spherical bearing 5. The outer spherical bearings 5 are connected to the rotating guide device 6 via bearing seat transition rings 4. Therefore, when the vibration table 1 and the vibration base plate 2 are vibrating, the rotating guide device 6 is in a synchronous vibration state. Under the action of the positioning structure, the vibration table 1 can smoothly provide a vibration environment for the rotating guide device 6.
[0025] like Figure 4 , Figure 5 As shown, the rotating unit includes a drive motor 21, which is connected to a bearing housing 17 via a convex block 20. The bearing housing 17 is mounted on the top of a frame 19 via a seated bearing 18. A controller 13 adapted to the drive motor 21 is mounted on the frame 19. Under the control of the controller 13, the operating state of the drive motor 21 can be controlled, thereby providing power for the operation of the rotating unit and enabling the rotating unit to smoothly control the rotation of the rotating guide device 6.
[0026] Furthermore, the rotating unit also includes a drive shaft 12 distributed parallel to the rotating guide device 6. The end of the drive shaft 12 away from the rotating guide device 6 is mounted on the bearing housing 17. The drive shaft 12 is connected to the drive motor 21 through a synchronization structure. Under the connection of the synchronization structure, the drive motor 21 in operation can drive the drive shaft 12 to rotate smoothly.
[0027] Specifically, such as Figure 1 , Figure 2 As shown, the synchronization structure includes a V-belt pulley 14 located at the output end of the drive motor 21, a V-belt pulley 15 located on the transmission shaft 12, and a V-belt 16 connecting the two. When the drive motor 21 operates, the transmission shaft 12 rotates synchronously above the rotating guide device 6. The combination of V-belt pulley 14, V-belt pulley 15, and V-belt 16 has a buffering effect, which can reduce the impact of the vibration table 1 on the drive motor 21 during operation and improve the smoothness of the transmission shaft 12 during rotation.
[0028] The transmission structure includes a toothed synchronous pulley 2 8 and a toothed synchronous pulley 10 distributed from bottom to top, and an HTD synchronous belt 9 connecting the two. The end of the rotating guide device 6 is provided with a synchronous pulley adapter 2 7 that is connected to the toothed synchronous pulley 2 8. The transmission shaft 12 is provided with a synchronous pulley adapter 11 that is connected to the toothed synchronous pulley 10. When the transmission shaft 12 rotates, the rotating guide device 6 rotates synchronously above the vibration table 1.
[0029] The synchronous structure and transmission structure can reduce the impact of the vibration force of the vibration table 1 on the rotary guide device 6 and the rotating unit, effectively avoid the phenomenon of displacement and detachment of the rotary guide device 6 under vibration, and accurately transmit the operating force of the transmission shaft 12, improve the accuracy of the rotational force in the transmission process, and ensure the test quality.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
