Description

Technical Field

[0001] This invention belongs to the field of oil drilling equipment technology, specifically relating to an automated processing system for parallel high-position connection and disconnection of drilling rig tubing, and also to an automated processing method for parallel high-position connection and disconnection of drilling rig tubing. Background Technology

[0002] Conventional oilfield single-lift drilling rigs are equipped with automated tubing systems that include a complex array of equipment such as a power catwalk, drilling robot, iron drill, drilling winch, secondary platform, and pusher robot. During drilling, the top drive plays a crucial role, actively participating in the drilling operation by transmitting torque and axial force to the drill string, driving the drill bit to rotate and break rock. However, this operating mode has significant limitations. Due to the working characteristics of the top drive and the coordination mechanism of the entire automated tubing system, it is impossible to simultaneously perform stand-up rod ejection or secondary platform stand-up rod placement while the top drive is running. This is because the core function of the top drive is rotating the drill pipe during operation. Simultaneously, its large structure occupies critical space on the drilling rig, and the related power transmission lines and control systems are under heavy load. Simultaneously performing stand-up rod ejection or placement operations not only carries the risk of collisions and interference between equipment but could also lead to serious safety accidents, such as stand-up rod falls or equipment damage.

[0003] During non-drilling operations, the drilling rig needs to complete various string handling tasks, including connecting standpipes, transferring standpipes from the wellhead to the second-level platform finger beam area, and swinging standpipes or single standpipes within the wellhead area to the catwalk. These seemingly routine string handling tasks actually consume a significant amount of time. First, connecting standpipes requires precise alignment and reliable connection operations, involving the coordination of multiple pieces of equipment such as the drilling rig's robotic arm and the steel driller; any problem in any link can lead to operation delays. For transferring standpipes to the second-level platform finger beam area, the second-level platform and the pusher robotic arm need to work precisely together to accurately place the standpipes within the finger beams, overcoming factors such as the weight, length, and space limitations of the standpipes. The swinging operation ensures that standpipes or single standpipes can be safely and stably transferred from the wellhead to the catwalk, with equipment such as pneumatic winches playing a role, but the entire process also faces challenges such as equipment stability and operational precision. Because these string handling operations take too long, the actual effective drilling time is severely limited, making it impossible to achieve the efficient mode of drilling and unloading the drilling rig simultaneously. This results in low overall drilling efficiency and affects the progress and economic benefits of oil extraction. Summary of the Invention

[0004] The purpose of this invention is to provide an automated processing system for the drilling rig tubing of parallel high-position stand-up drilling rigs, which realizes an efficient mode of drilling and stand-up drilling operations simultaneously.

[0005] Another objective of this invention is to provide an automated method for handling the drilling rig tubing of parallel high-position drilling rigs with vertical shafts.

[0006] The technical solution adopted in this invention is an automated processing system for parallel high-position connection and disconnection of drilling rig tubing, including a power catwalk located directly in front of the drilling rig base, which is connected to the drilling platform located on the drilling rig base; a derrick is installed on the drilling platform, a top drive is installed on the derrick, and a clamping drilling platform manipulator is installed on the drilling platform; a second-level platform is installed on the derrick, the front end of the second-level platform has an open structure, and a push-type second-level platform manipulator is installed on the second-level platform of the derrick; a drilling platform winch is installed on the drilling platform on the drilling rig base, and the drilling platform winch is connected to the standpipe via a steel wire rope.

[0007] The invention is further characterized in that, The hydraulic lifting clamp is located above the wellhead and is connected to the top drive.

[0008] The wellhead is equipped with a driller's cabin and a driller's cabin, respectively, and the driller's control system is connected to the driller's cabin.

[0009] Finger beams are installed on the second-level platform for storing the support posts.

[0010] A monkey platform is also installed on the upper part of the derrick.

[0011] The height of the monkey platform is higher than that of the second-floor platform.

[0012] Another technical solution adopted in this invention is an automated processing method for parallel high-position connection and disconnection of drilling rig tubing, specifically as follows: During non-drilling periods: with the participation of the top drive, the standpipe is connected and the standpipe is discharged from the wellhead to the second platform finger beam area, and the standpipe or single standpipe is ejected from the wellhead area to the catwalk. At this time, the upper end of the standpipe is tilted out from below the second platform under the lifting of the top drive. During drilling: the drilling rig can simultaneously drill a well and receive the stand-up pole arrangement sent from the power catwalk ramp offline, or perform a two-way operation of throwing the stand-up pole directly from the second platform to the ramp. The method for lowering the stand-up pole directly from the second-level platform to the power catwalk ramp is as follows: the stand-up pole placed on the finger beam is lifted by the steel cable of the pneumatic winch. With the support of the drilling rig robot and the push of the second-level platform robot, the stand-up pole is sent from inside the derrick through the opening at the front end of the second-level platform to the power catwalk ramp, thus completing the stand-up pole lowering operation. The working method for discharging the standoff from the power catwalk ramp to the finger beam is as follows: the standoff delivered from the power catwalk ramp is lifted by a steel cable, supported by the drilling rig robot, and pushed by the second-level platform robot. The standoff is discharged from the outside of the derrick through the front opening of the second-level platform into the inside of the finger beam of the second-level platform.

[0013] The beneficial effects of this invention are as follows: The automated tubing handling system of this invention effectively improves the working efficiency of oil drilling rigs. Firstly, during drilling and non-drilling periods, the drilling rig can lift the standpipes using the rig winch, push and support them with the second-level rig manipulator, and assist them with the rig manipulator on the drilling surface, enabling the standpipes to be directly dropped from the front opening of the second-level rig to the ramp at a high position on the second-level rig. Secondly, during drilling and non-drilling periods, the drilling rig can discharge the standpipes from the catwalk ramp to the finger beam section of the second-level rig without using the top drive, allowing for simultaneous drilling and receiving of standpipes from the catwalk ramp. Through these two methods, the discharge of second-level rig standpipes and the dropping of the standpipes on the ramp can be completed during drilling, saving a significant amount of time previously spent on standpipe discharge and dropping of the standpipes on the ramp during non-drilling periods, thus effectively improving drilling efficiency.

[0016] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0017] Example 1 In existing drilling rig string operations, such as Figure 1 As shown, during non-drilling periods, the drilling rig performs string operations such as connecting the standpipe 2 and discharging the standpipe from the wellhead to the second-level platform finger beam 10 area (from the wellhead to the left and right finger beam areas in the figure), as well as ejecting the drill string from the standpipe 2 within the wellhead range or to the power catwalk 1 (from the wellhead to the power catwalk in the figure, at this time the movement of the standpipe 2 is under the lifting of the top drive 6, and the upper end of the standpipe is tilted out from below the second-level platform 11). The top drive 6 is required to participate in the lifting. The above string operations cannot be performed during drilling.

[0018] Example 2 This invention relates to an automated processing system for parallel high-position connection and disconnection of drilling rig tubing, such as... Figure 2 As shown, it includes a power catwalk 1 located directly in front of the drilling rig base, which is connected to the drilling platform located on the drilling rig base; a derrick is installed on the drilling platform, a top drive 6 is installed inside the derrick, and a clamping drilling platform robot 3 is installed on the drilling platform. The derrick is equipped with a second platform 11. The front end of the second platform 11 is an open structure. The second platform 11 is firmly connected to the main structure of the derrick and can withstand various loads during the operation of the derrick 2. The second-level platform of this invention has a front-opening structure. During drilling, the drilling rig can lift the support column using a pneumatic winch, and the second-level platform robot can push and support the support column. With the support of the drilling platform robot on the drilling platform surface, the operation of throwing the support column directly from the front opening of the second-level platform to the ramp can be realized at a high position on the second-level platform. It can also realize bidirectional operation of the support column sent from the catwalk ramp to the second-level platform.

[0019] A push-type second-level platform manipulator 4 is installed on the second-level platform 11 of the derrick; the second-level platform manipulator 4 is used to support and transfer the pipe string anchor between the wellhead, the rat hole, and the second-level platform 11.

[0020] Above the wellhead is a hydraulic clamp 5, which is connected to the top drive 6 inside the derrick. The hydraulic clamp 5 and the top drive work together. When lifting the tubing string, the hydraulic clamp can firmly clamp the tubing string, bear the weight of the tubing string, and move with the movement of the lifting system.

[0021] Example 3 The drilling platform winch 7 is installed on the drilling platform of the drilling rig. The drilling platform winch 7 is connected to the stand 2 via steel wire rope 13. The iron drill 8 and the driller's room 9 are installed on both sides of the wellhead. The iron drill 8 works closely with the hydraulic hoist 5, top drive 6 and other equipment to clamp the stand 2. In addition, the control system of the iron drill 8 is connected to the driller's room 9. The driller's cabin (9) serves as the control and communication center for the entire automated drilling rig string handling system. It is connected to various devices (such as the hydraulic hoist (5), pneumatic winch (7), and steel driller (8)) via cable or wireless communication. The driller can precisely control these devices from within the cabin using the control console, including adjusting parameters such as device start-up, stop, speed, and direction.

[0022] Finger beams 10 are installed on the second-tier platform 11 to store the uprights 2; A monkey platform 12 is also installed on the upper part of the derrick. The height of the monkey platform 12 is higher than that of the second-level platform 11, so that there is enough space for operation and observation in the upper part of the derrick.

[0023] The automated stand-up drilling rig tubing processing system of the present invention not only enables the connection of stand-up poles and the discharge of stand-up poles from the wellhead to the second-level platform finger beam area, as well as the discharge of stand-up poles or single poles from the wellhead area to the catwalk; but also enables bidirectional movement of stand-up poles between the second-level platform finger beam area and the catwalk ramp during the drilling process. This allows for simultaneous drilling and offline reception of stand-up pole arrangements from the catwalk ramp or the discharge of stand-up poles directly from the second-level platform to the ramp. This bidirectional stand-up operation effectively improves the working efficiency of oil drilling rigs.

[0024] Example 4 The present invention provides an automated processing method for parallel high-position connection and disconnection of drilling rig tubing, specifically comprising: During non-drilling periods: With the participation of the top drive 6, the vertical root 2 and the vertical root 2 in the area from the wellhead to the second platform finger beam 10 are discharged, and the vertical root 2 or single root in the wellhead range is ejected to the catwalk. At this time, the upper end of the vertical root 2 is tilted out from below the second platform 11 under the lifting of the top drive 6. During drilling: The following is a two-way operation method: drilling a well while simultaneously receiving the standpipe arrangement from the power catwalk ramp or directly dropping standpipes from the second-level platform to the ramp. like Figures 3-5 As shown, the work of dropping the stand 2 directly from the second-level platform 11 to the ramp of the power catwalk 1 is as follows: the stand 2 placed on the finger beam 10 is lifted by the wire rope 13 of the drilling platform winch, supported by the drilling platform manipulator 3 on the drilling platform surface and pushed by the second-level platform manipulator 4, and sent from inside the derrick through the front opening of the second-level platform 11 to the ramp of the power catwalk 1, thus completing the stand 2 lowering operation. Work from the ramp of the power catwalk 1 to the discharge of the stand beam 10: The stand beam 2, which is sent from the ramp of the power catwalk 1, is lifted by the wire rope 13 of the drilling platform winch, supported by the drilling platform manipulator 3 on the drilling platform surface, and pushed by the second-level platform manipulator 4. The stand beam 2 is discharged from the outside of the derrick through the front opening of the second-level platform 11 into the inside of the second-level platform finger beam 10 of the derrick.

[0025] Example 5 Operations of the drilling rig during non-drilling periods Equipment preparation and initial status confirmation: Ensure that the top drive 6, wellhead, second-level platform finger beam 10, power catwalk 1, drilling platform robot 3, second-level platform robot 4, drilling platform winch 7 and wire rope 13 are all in normal working condition, and that the communication and control systems between each piece of equipment are well connected.

[0026] Check the storage and preparation of Ligen 2 to ensure that Ligen 2 is ready near the wellhead or the corresponding delivery location.

[0027] With the assistance of top drive 6, the connection operation for stand 2 begins. Top drive 6 descends to the appropriate position at the wellhead and connects to stand 2 via its own clamping and lifting devices. Utilizing the precise control function of top drive 6, accurate docking of stand 2 with the wellhead equipment is ensured, completing the stand connection operation.

[0028] For the discharge operation of the standpost 2 in the area of ​​the finger beam 10 from the wellhead to the second-level platform, the top drive 6 slowly lifts the standpost 2, causing it to gradually move upwards. During the movement, the upper end of the standpost 2 tilts out from under the second-level platform 11. Through pre-set sensors and a control system, the lifting speed and direction of the top drive 6 are precisely controlled to avoid collisions between the standpost 2 and the second-level platform 11 or other derrick structures. When the standpost 2 reaches the designated position near the finger beam 10 of the second-level platform, the second-level platform manipulator 4 is used for assisted positioning and pushing to accurately discharge the standpost 2 into the corresponding position within the finger beam 10 of the second-level platform.

[0029] When it is necessary to move the standpipe 2 or a single standpipe within the wellhead area to the catwalk, the top drive 6 also lifts the standpipe 2, making it a certain height away from the wellhead. Then, the powered catwalk and related conveying device are started, and the direction and position of the standpipe 2 are adjusted so that it moves towards the catwalk. During the movement, the stable conveying of the standpipe 2 is ensured by the auxiliary control of the drilling rig winch and the wire rope 13 until the standpipe 2 safely reaches the designated position on the catwalk.

[0030] Example 6 Offline operation implementation of drilling rig during drilling When the drilling rig needs to perform the work of swinging the anchor directly from the second platform 11 to the power catwalk 1 ramp during drilling, the drilling platform winch 7 is started first. The drilling platform winch 7 is connected to the anchor 2 located on the finger beam 10 through the wire rope 13.

[0031] The derrick winch 7 begins lifting stand 2, while the derrick manipulator 3 moves to a suitable position to support stand 2. During the lifting process, the second-level derrick manipulator 4 also begins operation, pushing and supporting stand 2 from the side of the second-level derrick 11. Through the coordinated work of these three components, stand 2 moves from inside the derrick and passes through the front opening of the second-level derrick 1. When stand 2 reaches the top of the ramp of the power catwalk 1, it is slowly lowered, completing the lowering operation of stand 2 onto the ramp of the power catwalk 1.

[0032] When a standpipe 2 is delivered from the ramp of the power catwalk 1, the wire rope 13 of the derrick winch is connected to the standpipe 2. The pneumatic winch starts the lifting operation, raising the standpipe 2 upwards from the ramp. At this time, the derrick manipulator 3 moves to a suitable position below the standpipe 2 to provide stable support. As the standpipe 2 continues to rise, the second-level derrick manipulator 4 prepares to receive the standpipe 2 at the front opening of the second-level derrick 11. When the standpipe 2 approaches the front opening of the second-level derrick 11, the second-level derrick manipulator 4 assists in guiding the standpipe 2 into the opening and pushes the standpipe 2 into the interior of the second-level derrick finger beam 10.

[0033] Through the above embodiments, the automated processing method for parallel high-position connection and disconnection of drilling rig tubing of the present invention can be realized, improving the operating efficiency of the drilling rig, reducing non-drilling time, and achieving more efficient oil drilling operations. In practical applications, the equipment parameters and operating procedures can be appropriately adjusted according to the specific drilling rig model and well site conditions.
