Description

Technical Field

[0001] This utility model belongs to the technical field of tubing rotary devices, and particularly relates to tubing rotary devices with pressure sensing function. Background Technology

[0002] In the oil production field, wellhead equipment is a crucial component. There are two main types of wellhead equipment: concentric and eccentric. During oil production, unidirectional wear occurs in the tubing; dynamic loads on the sucker rod cause bending, leading to unidirectional wear on both the sucker rod and tubing. Continuous unidirectional wear can result in tubing perforation, sucker rod breakage, and significantly shorten the lifespan of both the tubing and sucker rod, thus increasing crude oil production costs. Rotating the tubing can distribute the wear more evenly, maximizing its lifespan.

[0003] Currently, conventional tubing rotators primarily rely on mechanical structures to achieve the periodic rotation of the tubing, but lack the ability to monitor downhole conditions in real time. In practical applications, pressure changes and water cut fluctuations experienced by the tubing are key factors affecting oil production efficiency and equipment lifespan. However, existing technologies rarely integrate sensor monitoring functions into the rotator, resulting in operators being unable to obtain downhole data in a timely manner, making it difficult to optimize oil production processes and prevent malfunctions. Utility Model Content

[0004] The purpose of this invention is to solve the aforementioned technical problems in the prior art and to provide a tubing rotator with pressure sensing function. By integrating a pressure sensor and a water cut sensor, it enables real-time monitoring and remote data transmission of downhole operating conditions, thereby optimizing the tubing rotation strategy and extending the equipment life.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A tubing rotator with pressure sensing function includes a main body with a through-hole for mounting; a sleeve installed in the mounting cavity and connected to the main body; and a hanger mandrel installed in the sleeve. The main body has an assembly hole on its side, which communicates with the mounting cavity. A pressure sensor and a moisture content sensor are installed in the assembly hole. Both the pressure sensor and the moisture content sensor are connected to the mounting cavity. A remote sensing data acquisition device is connected to the pressure sensor and the moisture content sensor to collect data from the pressure sensor and the moisture content sensor.

[0006] Furthermore, the pressure sensor and the moisture content sensor are provided with a first threaded connection part, and a corresponding second threaded connection part is provided in the assembly hole. The pressure sensor and the moisture content sensor are connected to the assembly hole by threads.

[0007] Furthermore, both the pressure sensor and the moisture content sensor are provided with grooves, in which sealing rings are installed.

[0008] Furthermore, the moisture content sensor is equipped with multiple flow holes.

[0009] Furthermore, the main body has an assembly box for integrating components.

[0010] Furthermore, the suspension mandrel has a connecting section, and a sleeve is fitted outside the connecting section. The connecting section has an annular groove, and a sealing ring is installed inside the annular groove.

[0011] Furthermore, a thrust bearing is fitted onto the suspension mandrel, and a limiting boss is formed at the connection between the suspension mandrel and the connecting section. A limiting boss is provided on the sleeve, and the thrust bearing is located between the limiting boss and the limiting boss.

[0012] Furthermore, it also includes a power mechanism, which is connected to the suspension spindle. The power mechanism is used to provide power to drive the suspension spindle to rotate. The power mechanism is connected to a speed sensor, which is connected to a remote sensing data acquisition unit.

[0013] Furthermore, the power mechanism includes a drive motor, a first worm, a first turbine, a second worm, and a second turbine. The second turbine is sleeved on the suspension spindle, the second worm meshes with the second turbine, the first turbine is installed at one end of the second worm, the first worm meshes with the first turbine, and the drive motor is connected to the first worm.

By integrating multiple types of sensors and remote sensing data acquisition devices, real-time monitoring of downhole pressure, water cut, and rotation speed was achieved, providing a data foundation for optimizing oil production processes and significantly improving production efficiency and equipment reliability.

Relying on remote sensing data transmission and precise control of the power mechanism, remote monitoring and intelligent adjustment of the tubing rotator have been realized, reducing manual intervention and promoting the development of oil production operations towards automation and intelligence.

Detailed Implementation

[0019] like Figures 1 to 10 As shown, this utility model is a tubing rotator with pressure sensing function, including a main body 1, a sleeve 3, a suspension mandrel 4 and a power mechanism. The main body 1 has a through-hole 2. The sleeve 3 is installed in the installation cavity 2 and connected to the main body 1. The suspension mandrel 4 is installed in the sleeve 3. The power mechanism is connected to the suspension mandrel 4 and is used to provide power to drive the suspension mandrel 4 to rotate.

[0020] The main body 1 has two assembly holes 5 on its side, which are connected to the mounting cavity 2. A pressure sensor 6 and a moisture content sensor 7 are installed in the two assembly holes 5 respectively. Both the pressure sensor 6 and the moisture content sensor 7 are connected to the mounting cavity 2. The pressure sensor 6 and the moisture content sensor 7 are connected to a remote sensing data acquisition device 8. The power mechanism is connected to a speed sensor 19, which is connected to the remote sensing data acquisition device 8. The remote sensing data acquisition device 8 is used to collect data from the pressure sensor 6, the moisture content sensor 7, and the speed sensor 19, realizing real-time monitoring of the internal pressure and moisture content of the oil pipe. This avoids equipment wear or failure due to unclear operating conditions. At the same time, the addition of the speed sensor 19 enables the equipment to monitor the rotation speed in real time and adjust the power output in a timely manner, avoiding equipment failure or efficiency reduction due to abnormal speed.

[0021] Both the pressure sensor 6 and the moisture content sensor 7 are provided with a first threaded connection part 9, and a corresponding second threaded connection part 10 is provided in the assembly hole 5. The pressure sensor 6 and the moisture content sensor 7 are connected to the assembly hole 5 by threads. The threaded connection method not only makes installation simple, but also enhances the stability and sealing of the sensor, and can effectively prevent the sensor from loosening or falling off under high pressure.

[0022] Both the pressure sensor 6 and the moisture content sensor 7 are provided with a groove 11, which is used to install a sealing ring to prevent leakage.

[0023] The moisture content sensor 7 is equipped with multiple flow holes 12. The design of the flow holes 12 allows the fluid to fully contact the sensor probe, which improves the accuracy and response speed of moisture content measurement and avoids data deviation caused by fluid stagnation.

[0024] The moisture content sensor 7 has a detection head inside, and a temperature sensor is separately installed at the end of the detection head. After the oil is extracted, it passes through the moisture content sensor 7 and comes into contact with the detection head. The detection head emits electrodes to obtain the temperature and moisture content.

[0025] The main body 1 has an assembly box 13, which is used to integrate components such as remote sensing data acquisition unit 8, drive motor 20 and speed sensor 19.

[0026] The remote sensing data acquisition unit 8 is equipped with a patch antenna, which enables wireless remote data transmission, reduces wiring complexity, and enhances the adaptability and communication stability of the equipment under complex well conditions.

[0027] In this utility model, the pressure sensor 6 is model WCPS400-FP51-063BG, the moisture content sensor 7 is model IFW-2B, and the remote sensing data acquisition device 8 is model PZ-3657D-S002.

[0028] The suspension mandrel 4 is provided with a connecting section 14, which is located at the top of the suspension mandrel 4. The sleeve 3 is sleeved on the outside of the connecting section 14. The suspension mandrel 4 is driven to rotate by a power mechanism, so that the suspension mandrel 4 and the sleeve 3 rotate relative to each other. The connecting section 14 is provided with an annular groove 15. Multiple annular grooves 15 can be provided according to actual conditions. A sealing ring is installed in the annular groove 15. A thrust bearing 2616 is sleeved on the suspension mandrel 4. A limiting boss 17 is formed at the connection between the suspension mandrel 4 and the connecting section 14. A limiting boss 28 is provided at the bottom end of the sleeve 3. The thrust bearing 2616 is located between the limiting boss 17 and the limiting boss 28. One side of the thrust bearing 2616 abuts against the limiting boss 17, and the other side abuts against the limiting boss 28. The combined design of the thrust bearing 2616 and the limiting boss effectively distributes the axial load, reduces the wear of the suspension mandrel 4, and ensures the smoothness and reliability of the rotation process.

[0029] The power mechanism includes a drive motor 20, a first worm 21, a first turbine 22, a second worm 23, and a second turbine 24. The second turbine 24 is keyed onto the hanger spindle 4 and located below the limiting boss 18. The second worm 23 meshes with the second turbine 24. The first turbine 22 is installed at one end of the second worm 23. The first worm 21 meshes with the first turbine 22. The drive motor 20 is connected to the first worm 21 and drives the first worm 21 to rotate. The first worm 21 drives the first turbine 22 to rotate, which in turn drives the second worm 23 to rotate. The second worm 23 then drives the second turbine 24 to rotate. Since the second turbine 24 is mounted on the hanger spindle 4, it causes relative rotation between the hanger spindle 4 and the sleeve 3. Bearings 26 are installed at both ends of the first worm 21. The bearings 26 reduce the rolling friction between the first worm 21 and the rollers during rolling, thereby reducing friction loss and energy loss in the transmission system, improving transmission efficiency, and extending service life.

[0030] A sealing ring 25 is fitted on the suspension spindle 4. The sealing ring 25 is located below the second turbine 24 and limits the second turbine 24.

[0031] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
