Description

Technical Field

[0001] This invention belongs to the field of petroleum equipment, and specifically relates to a test device for the rotary joint of a coiled pipe working machine. Background Technology

[0002] In recent years, with the promotion and application of coiled tubing technology, the operational fields of coiled tubing equipment have become increasingly broad, the operational processes increasingly complex, and the requirements for the overall performance of coiled tubing equipment have gradually increased. Specifically, the operating well depth has expanded from over 1,000 meters in Daqing Oilfield to over 8,000 meters in Xinjiang Oilfield, and the operating pressure has expanded from below 10 MPa in Qinghai Oilfield to around 50 MPa in shale gas. Whether it's the increase in the length and diameter of the coiled tubing or the increase in operating pressure, it all places a great challenge on the performance of the drum. The stable performance of the rotary joint inside the drum plays a crucial role in the promotion and application of coiled tubing equipment in emerging fields.

[0003] Currently, rotary joint testing methods first require a fully functional roller and a power system for the roller. After assembling the rotary joint to be tested onto the roller, the roller is rotated using the external power system to test the flexibility and stability of the rotary joint's rotation. Then, the roller assembly with the rotary joint and internal / external manifold installed is subjected to a pressure test on the entire manifold in a static state to check the sealing performance of the rotary joint. Traditional rotary joint testing methods are demanding in terms of equipment, cumbersome in process, labor-intensive, lack clear fault diagnosis, are costly, and cannot test the sealing performance of the rotary joint while it is rotating, leading to significant uncertainty in the performance assessment of the rotary joint. Summary of the Invention

[0032] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0033] Example: Figure 1 and 2 As shown, the rotary joint testing device for a continuous tube machine in this embodiment includes a frame 1, a rotating shaft 2, a rotary joint movable end fixing assembly 3, a rotary joint fixed end fixing assembly, a rotation power system, and a pressure testing system 6. The rotating shaft 2 is horizontally rotatably mounted on the frame 1. The rotary joint movable end fixing assembly 3 is connected to one end of the rotating shaft 2. The rotary joint fixed end fixing assembly is mounted on the frame 1 and close to the rotary joint movable end fixing assembly 3. The rotation power system is mounted on the frame 1 and is connected to the other end of the rotating shaft 2 for driving the rotating shaft 2 to rotate. The pressure testing system 6 has a pressure testing pipeline, which is detachably connected to the liquid inlet of the rotary joint fixed end for injecting liquid into the rotary joint whose outlet is blocked.

[0034] The usage process is as follows:

[0035] The fixed end (i.e., the main body) of the rotary joint of the continuous tube machine is fixed by the rotary joint fixed end fixing assembly. At the same time, the movable end of the rotary joint is positioned and connected by the rotary joint movable end fixing assembly 3. Next, the rotary power system is started to drive the rotating shaft 2 to rotate, thereby driving the movable end of the rotary joint to rotate relative to the fixed end through the rotary joint movable end fixing assembly 3. During this process, observe whether there is any jamming or unsmooth rotation of the rotary joint. Combined with the current output speed of the rotary power system, the rotational performance of the rotary joint under dynamic testing can be obtained. In addition, before the test, the pressure testing system 6 is connected to the liquid inlet of the fixed end of the rotary joint through the pressure testing pipeline (the liquid outlet of the rotary joint is pre-sealed) so that the sealing performance inside the rotary joint under dynamic rotation can be measured.

[0036] The entire device has a simple structure and lightweight design, making it easy to learn and use. It can be operated after simple training. It is convenient to operate, which can effectively reduce the intensity of manual labor and improve the practicality of testing.

[0037] In this embodiment, in order to facilitate the movement of the entire device, casters can be installed at a suitable position at the bottom of the frame 1 to enable the movement of the entire device.

[0038] As a preferred implementation method, such as Figure 1 As shown, the upper end of the frame 1 is provided with a rotating mounting plate 11, and the two sides of the rotating mounting plate 11 are respectively provided with a power mounting plate 12 and a fixing plate 13. The rotating shaft 2 is horizontally rotatably mounted on the upper end of the rotating mounting plate 11, and its two ends extend upward toward the power mounting plate 12 and the fixing plate 13 respectively. The rotating power system is mounted on the upper end of the power mounting plate 12, and the rotating joint fixing end fixing assembly is mounted on the upper end of the fixing plate 13.

[0039] In this implementation scheme, the frame 1 is equipped with corresponding rotating mounting plates 11, power mounting plates 12 and fixed plates 13 according to the distribution of each major component, so that the layout of each component in the whole equipment is more reasonable, the initial assembly and subsequent maintenance are more convenient, thereby improving the efficiency of testing.

[0040] In this embodiment, the rotating mounting plate 11, the power mounting plate 12, and the fixed plate 13 are arranged in a stepped structure. Specifically, the power mounting plate 12 has the lowest height, the rotating mounting plate 11 has the highest height, and the fixed plate 13 has a height that is slightly lower than the rotating mounting plate 11 and higher than the power mounting plate 12.

[0041] In this embodiment, the assembly of the rotating shaft 2 on the rotating mounting plate 11 includes at least the following two structural methods:

[0042] A bushing is horizontally fixed on the rotating mounting plate 11 by fasteners (bolts or clamps, etc.), and the rotating shaft 2 passes through the bushing and rotates with the bushing.

[0043] A bearing is installed on the upper end of the aforementioned rotating mounting plate 11, and the rotating shaft 2 passes through the inner ring of the bearing and is connected and assembled to achieve relative rotation.

[0044] In a preferred embodiment, the rotary joint movable end fixing assembly 3 includes a rotary positioning plate 31 and a positioning component. The rotary positioning plate 31 is vertically arranged and is vertically connected and fixed to one end of the rotary shaft 2. The positioning component is disposed on the side of the rotary positioning plate 31 opposite to the rotary shaft 2. The positioning component is used to connect with the movable end of the rotary joint so as to drive the movable end of the rotary joint to rotate relative to the fixed end.

[0045] In this implementation scheme, the structure of the rotating joint movable end fixing component 3 is relatively simple. The positioning component and the end of the rotating shaft 2 are connected by rotating positioning plate 31. The movable end of the rotating joint is positioned by the positioning component. During the rotation of the rotating shaft 2, the positioning component and the movable end of the rotating joint are rotated. However, it should be noted that the rotation center of the movable end of the rotating joint relative to the fixed end is on the same axis as the rotation center of the rotating shaft 2.

[0046] More specifically, the positioning assembly includes two parallel and spaced support rods 32, which are respectively vertically fixed to the side of the rotary positioning plate 31 opposite to the rotating shaft 2. The two support rods 32 are eccentrically positioned with respect to the rotating shaft 2, and the movable end of the rotary joint passes through the gap between the two support rods 32.

[0047] In this scheme, since the rotary joint of the continuous tube machine is L-shaped, that is, the movable end and the fixed end are perpendicular to each other, after the fixed end is fixed on the fixed plate 13, the movable end can be driven to rotate during the rotation of the rotating shaft 2 by inserting the movable end between the two support rods 32. The structural design of the positioning component is relatively simple and can effectively position the movable end of the rotary joint so that it can rotate well relative to the fixed end, thereby effectively testing its rotation performance.

[0048] Of course, the assembly position of the two support rods 32 on the rotary positioning plate 31 can be adjusted during the assembly process. The position that matches the movable end of the rotary joint can be reasonably selected.

[0049] Of course, for easier operation, the two support rods 32 can be assembled with sliding seats. The sliding seats can be slidably mounted on the rotating positioning plate 31 and, in conjunction with the corresponding sliding power device, realize automated operation to adjust the spacing.

[0050] In a preferred embodiment, the aforementioned rotary joint fixing end fixing assembly includes at least two fixing devices 4, which are respectively mounted on the fixing plate 13 and spaced apart along the long axis of the rotation shaft 2. Each fixing device 4 includes a support plate 41 and a clamping member 42. The support plate 41 is vertically mounted on the fixing plate 13, and the support plates 41 of the at least two fixing devices 4 are distributed in parallel. The upper end of the support plate 41 is provided with a "V"-shaped support groove. The clamping member 42 is installed on the upper end of the support plate 41 and is located above the support groove. The fixing end of the rotary joint rests on the support grooves of the at least two support plates 41 and is clamped to the upper end of the support plate 41 by the clamping member 42.

[0051] In this embodiment, both support plates 41 are perpendicular to the axis of the rotating shaft 2, and the spacing between them is distributed according to the length of the main body of the rotary joint. During assembly, the clamp 42 is pre-opened, and the main body of the rotary joint is placed on multiple support plates 41 and falls into the "V"-shaped support groove. Next, the main body of the rotary joint is clamped to the upper end of the corresponding support plate 41 by the clamp 42. Then, the movable end of the rotary joint is connected to the positioning component. The whole structure is simple in design, easy to operate, and the main body of the rotary joint is fixed firmly.

[0052] In the above embodiments, the clamp 42 can be any product model available on the market. When in use, the clamp 42 can flexibly select the appropriate size model according to the size of the main body of the rotary joint, thereby realizing the detection of different models of rotary joints and improving the practicality of the detection.

[0053] In a preferred embodiment, the rotary power system includes a motor 5 and a belt drive pair. The motor 5 is mounted on the power mounting plate 12, and its motor shaft is connected to the other end of the rotating shaft 2 via the belt drive pair.

[0054] In this implementation scheme, the rotary power system adopts a structural design of motor 5 and belt drive pair, which improves the shortcomings of the traditional test structure that achieves power output through the cooperation of roller motor and reducer, eliminates the interference of roller motor and reducer in the detection process in the traditional technology, and improves the accuracy of detection.

[0055] The above-mentioned belt drive pair is existing technology. Specifically, pulleys are respectively set at the other end of the drive shaft of motor 5 and the rotating shaft 2 (the size and specifications of the two pulleys are selected and assembled according to actual needs), and then the belt ring is put on the two pulleys.

[0056] Of course, the above-mentioned belt drive pair can be replaced by a combination of chain and sprocket drive pair (which is existing technology and will not be elaborated here).

[0057] In a preferred embodiment, a controller is also included, which is electrically connected to the motor 5 and connected to an external power source.

[0058] In this implementation scheme, the controller can control the operation and operating parameters of the motor 5. Furthermore, the controller can also be connected to the element on the motor 5 that tests the speed (such as an encoder) to realize real-time monitoring of the speed of the motor 5, which means that the rotational speed parameters of the rotating shaft 2 and the movable end of the rotary joint can be indirectly obtained.

[0059] In a preferred embodiment, the outer cover of the belt drive pair is provided with a safety guard 51, which is fixed to the frame 1.

[0060] In this implementation plan, the safety guard 51 is designed to protect workers from accidents caused by the exposed belt drive pair, and also to protect the belt drive pair itself from damage caused by foreign objects.

[0061] As a preferred implementation method, such as Figure 3 As shown, the pressure testing system 6 includes a loading frame 61 and a pressure pump 62 and a water tank 63 respectively installed on the loading frame 61. The inlet end of the pressure pump 62 is connected to the inside of the water tank 63 through a pipeline, and the outlet end of the pressure pump 62 is connected to the pressure pipeline.

[0062] In this implementation scheme, before testing, the outlet of the pressure pump 62 is connected to the inlet on the fixed end of the rotary joint through the pressure pipeline. During the test, liquid is pumped into the inner cavity of the rotary joint simultaneously during its rotation to test its internal pressure and sealing performance, thereby achieving dynamic sealing performance testing, also known as dynamic pressure testing, which improves the comprehensiveness of the test.

[0063] The aforementioned loading rack 61 can be mounted on the frame 1 or placed externally.
