Description

Technical Field

[0001] The present invention relates to the technical field of load testing of riser tensioners and guide wheels, and in particular to a load testing method for riser tensioners and guide wheels. Background Art

[0002] In offshore drilling operations, the structural design and equipment layout of the drilling platform are crucial for ensuring operational safety and efficiency. The ship's rig, a key operating area, has a lower surface approximately 10.7 meters from the main deck and 26.3 meters from the baseline, offering a high degree of spatial layout. Twelve guide wheels are installed on the rig's lower surface to guide the riser system. Six riser tensioners, totaling 12, are installed on each side of the rig to maintain stable tension in the riser system.

[0003] During load tests, it is often necessary to apply simulated loads to these guide wheels and riser tensioners to verify their load-bearing capacity and performance. However, due to the large moonpool area below the guide wheels, it is difficult to place the load-bearing tooling directly below the wellbore on the rig, which poses a significant layout challenge for the loading test. Furthermore, the test procedure requires multiple sets of different load tests on the 12 guide wheels and riser tensioners. This heavy workload and complex operation make traditional testing methods not only inefficient but also pose significant safety risks. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the traditional load test method is not only inefficient but also has great potential safety hazards.

[0005] In order to solve the above technical problems, the present invention provides a riser tensioner and guide wheel load test method, comprising the following steps:

[0006] Obtaining load test procedure requirements for the riser tensioner and the guide wheel, configuring a corresponding test load assembly according to the load test procedure requirements, and transporting the test load assembly to the bottom of the wellbore on the drilling platform by means of a transport device to perform a corresponding load test; wherein the gravity of the test load assembly is greater than the test load of the riser tensioner and the guide wheel in the corresponding load test;

[0007] Connecting both sides of the test load assembly to the riser tensioner and the guide wheel on different sides through force transmission links, so as to form a staggered force-applying structure with the riser tensioner and the guide wheel on both sides;

[0008] Determine the test load through the force transmission link, and perform all load tests in sequence starting from the minimum test load according to the load test procedure requirements;

[0009] Complete the load tests of the remaining watertight pipe tensioners and the guide wheels in sequence.

[0010] Furthermore, the gravity of the test load assembly is 1.2 times the test load of the riser tensioner and the corresponding guide wheel in the load test.

[0011] Furthermore, connecting both sides of the test load assembly to the riser tensioner and the guide wheel on different sides through force transmission links to form a staggered force-applying structure with the riser tensioner and the guide wheel on both sides includes:

[0012] A first steel wire rope is arranged on a first side of the test load assembly, and a first shackle, a first dynamometer, and a second shackle are sequentially connected in series. The first steel wire rope is obliquely extended and connected to the installation nodes of the riser tensioner and the guide wheel on the side to form a first force transmission link;

[0013] A second steel wire rope is symmetrically arranged on the second side of the test load assembly, and a third shackle, a second dynamometer, and a fourth shackle are sequentially connected in series. The second steel wire rope is obliquely extended and connected to the installation nodes of the riser tensioner and the guide wheel on this side to form a second force transmission link;

[0014] A staggered force-applying structure is formed by the first force transmission link and the second force transmission link.

[0015] Furthermore, the first dynamometer and the second dynamometer both have a telemetry function, so as to be connected to an external remote control center via Bluetooth, WiFi or infrared.

[0016] Furthermore, the two sides of the test load assembly are connected to the riser tensioner and the guide wheel on different sides through force transmission links to form a staggered force application structure with the riser tensioner and the guide wheel on both sides, which includes:

[0017] The test load assembly includes a load test tool and a counterweight. The weight of the corresponding counterweight is adjusted according to the requirements of the load test procedure to apply a corresponding load to the watertight pipe tensioner and the guide wheel.

[0018] Furthermore, determining the test load through the force transmission link and sequentially executing all load tests starting from the minimum test load according to the load test procedure requirements include:

[0019] Determining the load value applied by the test load assembly to the riser tensioner and the guide wheel by the first dynamometer and the second dynamometer;

[0020] Starting from the minimum test load value, the test load is increased in sequence according to the predetermined loading gradient until all load requirements are completed. Each loading stage is maintained for the set duration and response data is collected.

[0021] Furthermore, starting from the minimum test load value, the test load is increased in sequence according to the predetermined loading gradient until all load requirements are completed. Each loading stage is maintained for a set duration and response data is collected, including:

[0022] The loading gradient is 10%, 50%, 80% and 100% of the maximum load of the riser tensioner and the guide wheel, and the test load assembly applies the corresponding load to each group of the riser tensioner and the guide wheel in the order of the gradient;

[0023] Each loading phase is maintained for a set duration and response data is collected.

[0024] Furthermore, after completing the load test of the maximum load value of the watertight pipe tensioner and the guide wheel, a verification step of unloading to zero load is also included.

[0025] Furthermore, each set of riser tensioners and guide wheels includes at least one complete load test.

[0026] Furthermore, the test load assembly is located directly below the well center of the drilling platform.

[0027] Compared with the prior art, the load test method for a riser tensioner and a guide wheel according to the embodiment of the present invention has the following advantages:

DETAILED DESCRIPTION

[0034] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0035] like Figures 1 to 4 As shown, the present invention provides a method for testing a riser tensioner and a guide wheel load, comprising the following steps:

[0036] S110. Obtain the load test procedure requirements of the watertight pipe tensioner 1 and the guide wheel 2, configure the corresponding test load assembly 3 according to the load test procedure requirements, and transport the test load assembly 3 to the bottom of the well center of the drilling platform through the transportation equipment 4 to perform the corresponding load test; wherein the gravity of the test load assembly 3 is greater than the test load of the watertight pipe tensioner 1 and the guide wheel 2 in the corresponding load test.

[0037] It should be noted that the gravity of the test load assembly 3 in this step will apply a corresponding load to the riser tensioner 1 and the guide wheel 2 during the test. The test load of the riser tensioner 1 and the guide wheel 2 in the corresponding load test refers to the load limit that the riser tensioner 1 and the guide wheel 2 can withstand in each load test of the same set of load tests, according to the design specifications or technical standards required by the load test procedure for the riser tensioner 1 and the guide wheel 2.

[0038] This step avoids instability during the test process by limiting the gravity of the test load assembly 3 to be greater than the test load of the watertight pipe tensioner 1 and the guide wheel 2 in the corresponding load test, thereby ensuring safety.

[0039] S120. Connect both sides of the test load assembly 3 to the riser tensioner 1 and the guide wheel 2 on different sides through the force transmission link 5 to form a staggered force-applying structure with the riser tensioner 1 and the guide wheel 2 on both sides.

[0040] In this step, the force transfer link 5 is used to connect and form a staggered force structure, which helps to evenly distribute the load applied by the test load assembly 3 to the corresponding watertight pipe tensioner 1 and guide wheel 2, ensuring that all relevant components can be fully tested. At the same time, it reduces the risk of single-point overload, optimizes load distribution, and enables each tested piece to be inspected under conditions closer to actual working conditions, thereby improving the authenticity and effectiveness of the test.

[0041] S130 , determining the test load through the force transmission link 5 , and executing all load tests in sequence starting from the minimum test load according to the load test procedure requirements.

[0042] In this step, the force transmission link 5 is used to determine the test load value applied to the watertight pipe tensioner 1 and the guide wheel 2, and the load is gradually increased in order from small to large to perform all predetermined load tests. The performance of the equipment under different loads can be gradually verified to ensure that the equipment is not damaged or a safety accident is not caused by the sudden application of excessive load. By conducting the test in a step-by-step manner, the effectiveness of the test is guaranteed and the risks caused by sudden load changes are reduced.

[0043] It can be understood that in this step, load tests with different load requirements are carried out by configuring corresponding test load assemblies 3, and test load assemblies 3 of different weights are replaced by transportation equipment 4, thereby avoiding the situation where traditional load-bearing tooling is difficult to place directly below the well center of the drilling platform.

[0044] S140. Complete the load tests of the remaining riser tensioners 1 and guide wheels 2 in sequence.

[0045] Using this method, test load assemblies 3 of varying weights can be replaced using transport equipment 4, allowing for complete load testing of a set of riser tensioners 1 and guide wheels 2 with a single connection. This process can be repeated repeatedly until all equipment is tested, improving work efficiency. This reduces the number of repetitive operations and the potential safety hazards associated with multiple installation and removal steps, simplifying the operational process, improving test efficiency, and enhancing safety, thereby addressing the inefficiencies and safety hazards associated with traditional testing methods.

[0046] It should be noted that the connection between the test load assembly 3 and the riser tensioner 1 and guide wheel 2 in this embodiment is detachable, so that after the load test of one set of riser tensioners 1 and guide wheels 2 is completed, the next set of riser tensioners 1 and guide wheels 2 can be directly replaced for testing. The transportation equipment 4 in this embodiment is a BOP trolley.

[0047] Furthermore, the weight of the test load assembly 3 is 1.2 times the test load of the riser tensioner 1 and guide wheel 2 in the corresponding load test. By limiting the weight of the test load assembly 3, this embodiment can avoid instability during the test process, thereby ensuring safety.

[0048] Furthermore, the force transmission link 5 of this embodiment includes a first force transmission link 51 and a second force transmission link 52. Specifically, the two sides of the test load assembly 3 are connected to the riser tensioner 1 and the guide wheel 2 on different sides through the force transmission link 5 to form a staggered force application structure with the riser tensioner 1 and the guide wheel 2 on both sides, including:

[0049] S121. Deploy a first steel wire rope 511 on the first side of the test load assembly 3, and sequentially connect a first shackle 512, a first dynamometer 513, and a second shackle 514 in series. The first steel wire rope 511 is obliquely extended and connected to the mounting nodes of the riser tensioner 1 and the guide wheel 2 on that side to form a first force transmission link 51.

[0050] This embodiment deploys a first force transmission link 51 on the first side of the test load assembly 3, ensuring that the load applied by the test load assembly 3 is effectively transmitted to the riser tensioner 1 and guide wheel 2 via the first wire rope 511. A first dynamometer 513 monitors the applied load in real time, ensuring the accuracy of the load applied by the test load assembly 3 during testing. Furthermore, the use of a first shackle 512 and a second shackle 514 as connectors facilitates adjustment and maintenance, while also improving the safety of the entire system.

[0051] S122. A second steel wire rope 521 is symmetrically arranged on the second side of the test load assembly 3. The third shackle, the second dynamometer, and the fourth shackle are sequentially connected in series. The second steel wire rope 521 is obliquely extended to connect to the mounting nodes of the riser tensioner 1 and the guide wheel 2 on this side to form a second force transmission link 52.

[0052] By symmetrically placing a second force transmission link 52 on the second side of the test load assembly 3, the riser tensioner 1 and guide wheel 2 on both sides can evenly share the load applied by the test load assembly 3, preventing overloading on one side. Simultaneously, the second force gauge can independently monitor the load on the other side, providing more comprehensive data support and facilitating analysis of the overall performance of the equipment. This embodiment, through its symmetrical arrangement, enhances the stability of the overall structure and reduces the risk of system deflection or tilt due to asymmetric loading.

[0053] S123 , forming a staggered force-applying structure through the first force transmission link 51 and the second force transmission link 52 .

[0054] The staggered arrangement better simulates the complex stress state that the riser tensioner 1 and guide wheel 2 may encounter under real operating conditions, improving the authenticity and reliability of the test results. It also helps to optimize the distribution of load in the entire structure, reduce local stress concentration, and protect key components from excessive wear or damage.

[0055] Furthermore, both the first dynamometer 513 and the second dynamometer have a telemetry function, and can be connected to an external remote control center via Bluetooth, WiFi, or infrared.

[0056] The telemetry function of the first and second dynamometers 513 of this embodiment allows operators to monitor the load on each dynamometer in real time from a remote control center. This allows operators to promptly detect any abnormalities (such as overload) and take immediate corrective measures to avoid potential risks. Furthermore, since operators do not need to be physically present near the dynamometers during testing, they can remotely control and monitor the testing process from the remote control center, increasing operational safety and flexibility.

[0057] Specifically, the first dynamometer 513 and the second dynamometer of this embodiment support multiple wireless communication methods, such as Bluetooth, WiFi, or infrared. The most appropriate connection method can be selected based on actual conditions, thereby enhancing the adaptability and compatibility of the system and ensuring stable and reliable data transmission in various environments. For example, Bluetooth or infrared may be preferred in environments with significant electromagnetic interference, while WiFi may be preferred when a wider coverage area is required.

[0058] Furthermore, the two sides of the test load assembly 3 are connected to the riser tensioner 1 and the guide wheel 2 on different sides through the force transmission link 5 to form a staggered force application structure with the riser tensioner 1 and the guide wheel 2 on both sides, including:

[0059] The test load assembly 3 includes a load test fixture 31 and a counterweight 32. The weight of the corresponding counterweight 32 is adjusted according to the requirements of the load test procedure to apply a corresponding load to the watertight pipe tensioner 1 and the guide wheel 2.

[0060] The load test fixture 31 of this embodiment is a device used to simulate the force applied to the watertight pipe tensioner 1 and the guide wheel 2 in an actual working environment, and the counterweight 32 is a component used to adjust the total weight of the test load assembly 3. By changing the counterweight according to specific test requirements, different load conditions can be simulated to apply specific and controllable loads to the watertight pipe tensioner 1 and the guide wheel 2, ensuring that the test can be carried out under a series of preset conditions and collecting response data of the watertight pipe tensioner 1 and the guide wheel 2 under different working intensities to test their performance and reliability under different load conditions.

[0061] Furthermore, the test load requirement is determined through the force transmission link 5, and all load tests are performed sequentially starting from the minimum test load according to the load test procedure requirements, including:

[0062] S131, determining the load value applied by the test load assembly 3 to the riser tensioner 1 and the guide wheel 2 by the first dynamometer 513 and the second dynamometer;

[0063] This step uses the first dynamometer 513 and the second dynamometer to monitor and record in real time the load values ​​borne by the watertight pipe tensioner 1 under different operating conditions, ensuring that the test load component 3 operates according to the predetermined program requirements, thereby simulating the load conditions under actual working conditions.

[0064] S132. Starting from the minimum test load value, the test load is increased in sequence according to the predetermined loading gradient until all load requirements are completed. Each loading stage is maintained for a set duration and response data is collected.

[0065] This step gradually tests the performance of the riser tensioner 1 at different stress levels by increasing the load from small to large, helping to identify potential problems or weaknesses. Each loading stage is set for a specific duration to ensure the device can operate stably at each load level for a sufficient period of time, further verifying its reliability and durability. Response data (such as deformation and temperature changes) are systematically collected throughout the test process to provide a basis for subsequent analysis and help evaluate the device's true performance and safety.

[0066] The combination of the two steps in this embodiment not only ensures the comprehensiveness and accuracy of the load test, but also effectively avoids the safety hazards caused by the sudden application of high load by gradually increasing the load.

[0067] Furthermore, starting from the minimum test load value, the test load is increased in sequence according to the predetermined loading gradient until all load requirements are completed. Each loading stage is maintained for a set duration and response data is collected, including:

[0068] S1321, the loading gradient is 10%, 50%, 80% and 100% of the maximum load of the riser tensioner 1 and the guide wheel 2, and the test load assembly 3 applies the corresponding load to each set of riser tensioner 1 and guide wheel 2 in this gradient order;

[0069] This step can effectively evaluate the performance of the watertight pipe tensioner 1 and the guide wheel 2 under different stress levels by gradually increasing the load gradient from small to large, ensuring that they can operate stably under various working conditions. The lower load stage can help identify whether there are design or manufacturing defects in the equipment, while the high load stage is used to verify whether the equipment can withstand extreme conditions. The gradual increase in load helps avoid safety hazards caused by the sudden application of high loads.

[0070] S1322. Each loading phase maintains a set duration and collects response data.

[0071] Maintaining this step for a certain period of time allows the riser tensioner 1 to be fully stable at each load level, ensuring the accuracy of the test results. By collecting response data at each stage, the specific performance of the riser tensioner 1 and the guide wheel 2 under different load conditions can be understood in detail, providing a scientific basis for subsequent performance evaluation and possible improvements.

[0072] The combination of the two steps of this embodiment not only ensures a comprehensive and accurate load test of the riser tensioner 1 and the guide wheel 2, but also improves the safety and effectiveness of the test by gradually increasing the load.

[0073] Furthermore, after completing the load test of the maximum load value of the watertight pipe tensioner 1 and the guide wheel 2, a verification step of unloading to zero load is also included.

[0074] In this embodiment, after applying the maximum load value that the watertight pipe tensioner 1 and the guide wheel 2 can withstand and ensuring that they can work normally under extreme conditions and maintain it for a period of time, the load is gradually reduced until it is completely unloaded (i.e., zero load), and the state changes of the watertight pipe tensioner 1 and the guide wheel 2 after unloading from the maximum load to zero load are observed and recorded to determine whether they can be restored to the initial state or close to the initial state, so as to evaluate the elastic recovery ability of their materials and structural designs. If it has good rebound performance, it means that it can maintain stable performance during repeated loading and unloading. If permanent deformation or other abnormal conditions are found in the equipment during the unloading process, it may indicate the existence of design defects, material damage or manufacturing problems, so as to help operators take corrective measures to avoid more serious failures or accidents in the future.

[0075] Furthermore, each set of riser tensioner 1 and guide wheel 2 includes at least one complete load test.

[0076] By performing a complete load test, this embodiment can comprehensively evaluate the performance of each set of watertight pipe tensioners 1 and guide wheels 2 within the entire working range, ensuring that the watertight pipe tensioners 1 and guide wheels 2 can not only work normally under the designed maximum load, but also operate stably under various intermediate load conditions, thereby verifying their reliability and durability. If multiple complete load tests are carried out, a rough analysis of the service life can be made based on the experimental data.

[0077] In actual operation, the load borne by the watertight pipe tensioner 1 and the guide wheel 2 is usually applied along the centerline of the wellbore. The test load assembly 3 of this embodiment is located directly below the well center of the drilling platform, which can more realistically simulate the load conditions under the actual working environment, making the evaluation results closer to the actual situation and providing a reliable basis for accurate evaluation of equipment performance.

[0078] In summary, the present invention provides a method for load testing a riser tensioner and guide wheel. By using a transport device 4 to replace test load assemblies 3 of varying weights, a single connection is required to complete all load tests on a set of riser tensioners 1 and guide wheels 2. This process is repeated repeatedly until all equipment is tested, improving work efficiency. This reduces the number of repetitive operations and the potential safety hazards associated with multiple installation and disassembly, simplifies the operational process, improves test efficiency, and enhances safety, thus addressing the inefficiencies and safety hazards associated with traditional testing methods.

[0079] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
