Description

Technical Field

[0001] The invention relates to the technical field of oil and gas drilling, and in particular to a second-layer platform emergency pipe processing device and an operating method thereof. Background Art

[0002] At present, in the process of oil and gas drilling operations, the second-floor platform is an important working area for pipe discharge and processing. Under normal working conditions, the main pipe arranger undertakes the key task of arranging and transferring drill pipes, casings and other pipes in order, which plays a vital role in ensuring the efficient and orderly development of drilling work.

[0003] As oil and gas exploration and development continue to move towards deeper and more complex geological conditions, the environment and working conditions of drilling operations are becoming increasingly complex, and the reliability requirements for equipment are becoming higher and higher. However, in actual operations, the main pipe laying machine is in a high-load operation state for a long time, affected by the harsh field environment (such as wind, sand, humidity, high temperature, low temperature and other factors), as well as the wear and aging of the equipment's own parts, it is inevitable that failures will occur. Once the main pipe laying machine fails to work properly, it will seriously affect the continuity of drilling operations and may even cause a series of safety hazards, such as the pipes cannot be discharged and fixed in a timely and proper manner, which may easily cause accidents such as pipes falling and injuring workers or damaging other downhole equipment.

[0004] The traditional way to deal with the failure of the main pipe laying machine mainly relies on manual emergency operations, that is, manually operating various tools to complete the grabbing, moving and laying of pipes. However, this manual emergency treatment method has many obvious disadvantages:

[0005] First, from the perspective of work efficiency, manual operation is relatively slow and cannot meet the needs of drilling operations for fast and accurate handling of pipes. Especially when it is necessary to resume the drilling process as soon as possible and avoid long-term downtime, manual emergency operations often lead to significant delays in the progress of the operation, increasing the time and economic costs of the entire drilling project.

[0006] Second, manual operation poses a great safety risk. The second-floor platform is at a certain height, and workers need to face the risk of working at height when manually handling pipes and fixtures on it. At the same time, they also have to deal with unfavorable factors such as heavy pipes and fixtures and limited operating space. If they are not careful, casualties may occur, posing a serious threat to the life safety of on-site workers.

[0007] Third, the accuracy and stability of manual operation are poor. It is difficult to ensure that the pipes can be accurately grasped, moved and placed in the appropriate position every time by relying on manpower, which may further affect the arrangement of subsequent pipes and the convenience of reuse, and may even cause other potential safety and quality problems due to improper placement of pipes.

DETAILED DESCRIPTION

[0041] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0042] Embodiment 1:

[0043] like Figure 1-Figure 5 As shown, a specific embodiment of the present invention provides a second-layer platform emergency pipe handling device, including a main beam assembly 1, a cantilever beam assembly 2, a first traveling trolley 3, a second traveling trolley 4, a column assembly 5 and a clamp assembly 6; the main beam assembly 1 is installed on the derrick, and is located on the rear side of the second-layer platform main pipe laying machine on the derrick, the cantilever beam assembly 2 is rotatably installed on the bottom of the first traveling trolley 3, and the first traveling trolley 3 is movably installed on the main beam assembly 1; the second traveling trolley 4 is movably installed on the cantilever beam assembly 2, and the clamp assembly 6 is rotatably installed on the bottom of the second traveling trolley 4 through the column assembly 5; the first traveling trolley 3 can drive the cantilever beam assembly 2 to move along the main beam assembly 1, and the moving trolley can drive the cantilever beam assembly 2 to rotate in a horizontal plane, the second traveling trolley 4 can drive the column assembly 5 to move along the cantilever beam assembly 2, and the second traveling trolley 4 can drive the column assembly 5 to rotate in a horizontal plane.

[0044] Specifically, it constructs a flexible and efficient pipe handling system through the coordination of the main beam assembly 1, the cantilever beam assembly 2, the first walking trolley 3, the second walking trolley 4 and other components; and the main beam assembly 1 is installed on the rear side of the main pipe laying machine of the second-layer platform, and with the design of the cantilever beam assembly 2, the cantilever beam assembly 2 and the main beam assembly 1 are parallel when on standby, which can make full use of the limited space of the second-layer platform without affecting the normal use of the main pipe laying machine of the second-layer platform. When the main pipe laying machine of the second-layer platform fails, the first walking trolley 3 can drive the cantilever beam assembly 2 to move quickly along the main beam assembly 1, and can also drive the cantilever beam assembly 2 to rotate in the horizontal plane, and the second walking trolley 4 also has the function of driving the column assembly 5 to move along the cantilever beam assembly 2 and driving it to rotate in the horizontal plane. This multi-dimensional flexible movement mode enables the lifting clamp assembly 6 to quickly and accurately reach the position of the pipes that need to be processed, and realize the rapid grasping, moving and discharge operations of the pipes. Compared with the existing technology, it completely replaces manual operations, avoids safety accidents such as injuries and falls caused by pipe slippage and misoperation, and fundamentally eliminates major safety hazards in manual emergency operations; greatly improves the speed of pipe handling in emergency situations, effectively reduces the operation downtime caused by failure of the main pipe laying machine, ensures the continuity of drilling operations, and reduces time and economic costs.

[0045] Furthermore, if Figure 1 , Figure 6 and Figure 7 As shown, the main beam assembly 1 is provided with an installation opening extending along its length direction, and the inner side of the installation opening is provided with a first track 11 extending along its length direction; the first walking trolley 3 is movably installed on the first track 11. The installation opening extending along its length direction and the first track 11 on the inner side are provided on the main beam assembly 1, providing a precise and stable moving guide structure for the first walking trolley 3. The existence of the installation opening not only helps the installation and positioning of the track, but also guarantees the stability of the overall structure to a certain extent. The first track 11 enables the first walking trolley 3 to move smoothly along the length direction of the main beam assembly 1. This directional movement method ensures that the subsequent cantilever beam assembly 2 and other connected components can be adjusted on a predetermined route, laying the foundation for the entire device to accurately reach the pipes at different positions on the second-floor platform, thereby effectively improving the positioning accuracy and operation accuracy of the emergency pipe handling device, and enhancing the adaptability of the device under different pipe handling requirements. Specifically, the first traveling trolley 3 includes a first vehicle body 31, a first driving assembly, a first traveling roller 32 and a first rotating mechanism 33; the first vehicle body 31 is movably supported on the first track 11 by the first traveling roller 32, the first rotating mechanism 33 is installed at the bottom of the first vehicle body 31, the cantilever beam assembly 2 is installed on the first rotating mechanism 33, the first driving assembly is installed on the main beam assembly 1, and the first driving assembly is connected to the first vehicle body 31 to drive the first vehicle body 31 to move along the first track 11.

[0046] Furthermore, if Figure 6 and Figure 7 As shown, in this embodiment, the first drive assembly includes a first driver 34, a driving sprocket 35, a driven sprocket 36 and a chain 37; the first driver 34 is installed at one end of the main beam assembly 1, the driven sprocket 36 is installed at the other end of the main beam assembly 1, and both ends of the chain 37 are fixed on the first car body 31. The first car body 31 is connected to the driven sprocket 36 through the chain 37. The first driver 34 is connected to the chain 37 through the driving sprocket 35 to drive the driving sprocket 35 to rotate. The driving sprocket 35 rotates and drives the first car body 31 to move along the first track 11 through the chain 37. The chain 37 transmission has the advantages of long transmission distance, adaptability to complex spatial layout, and relatively large carrying capacity. In a specific environment such as a two-story platform, the layout of the various components of the device is relatively scattered and a certain amount of power needs to be transmitted to drive the trolley to move. The chain 37 transmission can well meet this demand, ensure stable power transmission, and thus ensure that the first car body 31 can move stably and reliably along the first track 11.

[0047] Furthermore, if Figure 1 , Figure 8 and Fig. 9 As shown, the cantilever beam assembly 2 has a second track 21 extending along its length direction; the second trolley 4 is movably mounted on the second track 21. The cantilever beam assembly 2 is provided with a second track 21 extending along its length direction, which provides a specific moving path for the second trolley 4, ensuring that the second trolley 4 can move smoothly along the length direction of the cantilever beam assembly 2. The setting of this track cooperates with the first track 11 on the main beam assembly 1, so that the device has a two-dimensional movement capability on the horizontal plane, further expands the spatial range that the lifting clamp assembly 6 can reach, improves the device's coverage of pipes at different positions on the second-floor platform, and enhances the flexibility and adaptability of the entire emergency pipe handling device to deal with various pipe placement situations, making it easier to approach and handle pipes more accurately, thereby improving the efficiency of emergency operations. Specifically, the second walking trolley 4 includes a second car body 41, a second driving assembly, a second walking roller 42 and a second rotating mechanism 43; the second car body 41 is supported on the second track 21 through the second walking roller 42, the second rotating mechanism 43 is installed at the bottom of the second car body 41, the column assembly 5 is installed on the second rotating mechanism 43, the second driving assembly is installed on the cantilever beam assembly 2, and the second driving assembly is connected to the second car body 41 to drive the second car body 41 to move along the second track 21.

[0048] Furthermore, if Figure 8 and Fig. 9As shown, in this embodiment, the cantilever beam assembly 2 is provided with a rack 22 extending along its length direction; the second driving assembly includes a second driver 44 and a second gear 45; the second driver 44 is connected to the rack 22 through the second gear 45 to drive the second gear 45 to rotate, and the rotation of the second gear 45 drives the second vehicle body 41 to move along the second track 21 through the rack 22. The use of the transmission mode of the second gear 45 and the rack 22 to drive the second vehicle body 41 to move has the advantages of high transmission accuracy, high efficiency, and compact structure. The power output by the second driver 44 can be accurately and efficiently converted into the moving power of the second vehicle body 41, so that the second vehicle body 41 can be accurately adjusted along the second track 21, further improving the accuracy of the movement of the device on the cantilever beam assembly 2, thereby improving the accuracy of the positioning of the pipe by the clamp assembly 6, which plays an important role in realizing refined emergency handling operations of pipes and avoiding problems such as improper handling of pipes due to positioning errors.

[0049] Furthermore, if Fig.10 As shown, the column assembly 5 includes an outer column 51, an inner column 52 and a telescopic driver 53; the outer column 51 is sleeved on the inner column 52, the tong assembly 6 is installed at the bottom of the inner column 52, and the two ends of the telescopic driver 53 are connected to the outer column 51 and the inner column 52 to drive the inner column 52 to drive the tong assembly 6 to rise and fall. Specifically, in this embodiment, the inner column 52 has guide grooves 54 on both sides, and the outer column 51 is provided with a composite roller 55 connected to the guide groove 54. The guide grooves 54 provided on both sides of the inner column 52 cooperate with the composite rollers 55 on the outer column 51 connected to the guide grooves 54, providing precise guidance and limiting for the lifting and lowering movement of the inner column 52. When the telescopic driver 53 drives the inner column 52 to lift the tongs assembly 6, the guide structure can ensure that the inner column 52 moves smoothly along the predetermined vertical direction, avoiding unstable conditions such as shaking and offset, and ensuring the vertical positioning accuracy of the tongs assembly 6, further improving the accuracy and stability of pipe grabbing and placing operations, so that the entire device can complete various tasks more reliably and accurately during emergency pipe handling, thereby ensuring the safety and efficiency of drilling operations.

[0050] Embodiment 2:

[0051] This embodiment provides an operation method of the second-floor emergency pipe handling device in Embodiment 1, comprising the following steps:

[0052] S1. The cantilever beam assembly 2 is driven to rotate in the horizontal plane to be perpendicular to the main beam assembly 1 through the first walking carriage, and the column assembly 5 is driven to rotate in the horizontal plane to the target angle through the second walking carriage 4. Specifically, the first rotating mechanism 33 of the first walking carriage 3 drives the cantilever beam assembly 2 connected thereto to rotate in the horizontal plane around the vertical axis, and the cantilever beam assembly 2 is rotated from a state parallel to the main beam assembly 1 until the cantilever beam assembly 2 and the main beam assembly 1 reach a vertical state. The second rotating mechanism 43 of the second walking carriage 4 drives the clamp assembly 6 to rotate to the target angle through the column assembly 5.

[0053] S2. According to the pipe storage position, the cantilever beam assembly 2 is driven by the first walking trolley 3 to move the target distance along the main beam assembly 1; then the column assembly 5 is driven by the second walking trolley 4 to move along the cantilever beam assembly 2 to the target position; specifically, the first driver 34 transmits power to the chain 37 through the active sprocket 35, and the chain 37 drives the first body 31 of the first walking trolley 3, and the first walking roller 32 on the first body 31 rolls along the first track 11 extending along the length direction of the inner side of the main beam assembly 1, and accurately drives the cantilever beam assembly 2 to move on the main beam assembly 1 according to the set target distance, so that the entire The device is close to the area where the target pipe is located in one dimension in the horizontal direction, laying the foundation for further precise positioning; the second driver 44 drives the second gear 45 to engage with the rack 22 on the cantilever beam assembly 2, and drives the second body 41 of the second walking trolley 4 to move along the second track 21 on the cantilever beam assembly 2 by relying on the second walking roller 42 at its bottom, driving the column assembly 5 and the lifting clamp assembly 6 to move along the length direction of the cantilever beam assembly 2 toward the precise storage position of the target pipe until it reaches the optimal target position for accurately grasping the pipe, thereby realizing the position adjustment of the device in another dimension on the horizontal plane.

[0054] S3. After lowering the clamp assembly 6 to a specified height through the column assembly 5, the pipe is clamped by the clamp assembly 6; then the column assembly 5 drives the clamp assembly 6 to lift the target pipe out of the storage position; specifically, the inner column 52 is driven to move downward along the outer column 51 by the telescopic driver 53, and the guide grooves 54 on both sides of the inner column 52 cooperate with the composite rollers 55 on the outer column 51 connected to the guide grooves 54 to ensure that the inner column 52 slides down smoothly in the vertical direction, driving the clamp assembly installed at the bottom of the inner column 52. The clamp assembly 6 is lowered according to the set specified height, so that the lifting clamp assembly 6 reaches a suitable height position, which is convenient for clamping the pipe; after the clamp assembly 6 completes the clamping, the telescopic driver 53 of the column assembly 5 runs in the reverse direction, and the inner column 52 is pulled upward along the outer column 51 by the telescopic driver 53. Relying on the guiding effect of the guide groove 54 and the composite roller 55, the inner column 52 rises steadily, driving the target pipe clamped by the lifting clamp assembly 6 to be lifted synchronously, so that the pipe gradually moves away from its original storage position.

[0055] S4, transport the pipe to the handover position through the first trolley 3 and the second trolley 4, and hand over the target pipe to the traveling lifting system on the derrick through the clamp assembly 6. Specifically, the first driver 34 of the first trolley 3 is started again, and the first driver 34 drives the first car body 31 to move along the first track 11 on the main beam assembly 1 through the active sprocket 35 and the chain 37; at the same time, the second driver 44 of the second trolley 4 is also started accordingly, and the second car body 41 is driven to move along the second track 21 on the cantilever beam assembly 2 through the transmission of the second gear 45 and the second rack 22. The two trolleys cooperate with each other, and rely on their respective walking rollers to roll on the track, driving the column assembly 5 and the pipe clamped by the clamp assembly 6 to move to the handover position in the horizontal direction, and then the target pipe is handed over to the traveling lifting system on the derrick through the clamp assembly 6 to complete the pipe grabbing operation.

[0056] The pipe laying operation is the process in which the traveling crane system delivers the pipes to the lifting clamp assembly 6 at the communication position and then transports the pipes to the storage position for storage. It is the reverse of the pipe grabbing operation and will not be described in detail here.
