Description

Technical Field

[0001] This application relates to the field of engineering machinery technology, specifically to drill pipe unhooking control methods, systems, devices, electronic equipment, and storage media. Background Technology

[0002] In one-click continuous drilling operations, when the automated equipment's iron driller uncouples at the wellhead, the unscrewing of the thread drives the drill rod upward.

[0003] If the number of shackle turns is insufficient, the drill pipe will not be unshackled, and the upper and lower drill pipes cannot be separated. If there are too many uncoupling turns, the drill rod will fall downwards due to its own weight, causing the threads at the end of the drill rod to re-engage, and the upper and lower drill rods will not be able to separate. In addition, if the force used to lift the upper drill pipe (male thread) and the axial deviation angle of the lower drill pipe (female thread) are too large after the drill pipe is disassembled, the male thread will be obliquely hung on the female thread, making it impossible to separate the drill pipe.

[0004] After the drill pipe is uncoupled, various reasons may cause the upper and lower drill pipes to be unable to separate. Therefore, the difficulty in separating the uncoupled upper and lower drill pipes has become a technical problem that urgently needs to be solved. Summary of the Invention

This method is applied to the driller control system and includes: The first distance the drill rod moves upward during the uncoupling process, sent by the iron driller at a preset cycle; Based on the first moving distance, a first control command is sent to the top drive winch system to control the hoist to be lifted in accordance with the lifting of the first drill pipe; The system receives the lifting height of the hoist from the top drive winch system and calculates the height difference between the cumulative moving distance of the first drill pipe and the overall lifting height of the hoist. If the height difference is less than a preset height threshold, the system sends a target instruction to the driller to unload the first drill pipe from the second drill pipe. The cumulative moving distance indicates the sum of the first moving distance during the uncoupling process, and the overall lifting height indicates the sum of the lifting height during the uncoupling process.

[0007] In one possible implementation, before receiving the first distance the first drill rod, sent by the driller at a preset cycle, has traveled during the uncoupling process, the method further includes: Send a descent command to the top drive winch system. The descent command is used to lower the first drill pipe a preset distance. Send the start unhooking command to the iron driller.

The cumulative travel distance indicates the sum of the first travel distance during the untying process, and the overall lifting height indicates the sum of the lifting height during the untying process. The driller receives the target command and, in response to the target command, releases the main clamp to complete the untying.

[0017] The drill pipe uncoupling control method proposed in this application has the following advantages over related technologies: The drill pipe uncoupling device includes a drill pipe, a steel driller, a top drive winch system, and a driller control system. The steel driller's main tongs are equipped with a displacement sensor to facilitate the acquisition of the drill pipe's lifting distance. The top drive winch system is equipped with an encoder and a lifting clamp to facilitate the acquisition of the drill pipe's lifting height. The drill pipe includes a first drill pipe and a second drill pipe, which are connected by threads. The method is applied to the driller control system and includes: receiving the first movement distance of the first drill pipe during the uncoupling process sent by the steel driller at a preset period, thus obtaining the movement distance of the drill pipe during the uncoupling process; and, based on the first movement distance, transmitting the data to the top drive winch system... The system sends a first control command to control the lifting chuck to rise in sync with the lifting of the first drill pipe, allowing the chuck to move synchronously with the rising distance of the first drill pipe. It receives the lifting height of the chuck from the top drive winch system and calculates the height difference between the cumulative moving distance of the first drill pipe and the overall lifting height of the chuck. If the height difference is less than a preset height threshold, it sends a target command to the driller to unload the first drill pipe from the second drill pipe, ensuring the chuck stably contacts the coupling of the first drill pipe, thereby lifting and supporting the first drill pipe. After unloading the first drill pipe from the second drill pipe, it maintains the current height of the first drill pipe, preventing it from falling into the female coupling of the second drill pipe, thus solving the coupling problem and achieving smooth uncoupling of the upper and lower drill pipes, improving the operational efficiency of oil drilling.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] The current leading technology for automation in oil drilling is one-button linkage technology. Its main function is to integrate various equipment on the drilling platform (iron driller, drilling platform robot, second-floor robot, hydraulic station, traveling block, winch, chuck, slips, catwalk, etc.) into an integrated control center through an integrated control system. This consolidates the commands of each device into a single command button or simple operating procedure, enabling advanced technology for automated collaborative operation of multiple devices. Its core objectives are to improve operational efficiency, ensure operational safety, and reduce reliance on manual labor, making it a core component of modern intelligent drilling. In the one-key linkage operation mode, there are important modes such as continuous tripping, continuous running down, one-key drill feeding, and one-key drill string ejection. Continuous tripping is the process of continuously raising the drill string to the surface. It includes several stages: drill string lifting, drill string uncoupling, drill string storage, and working intervals. The drilling components involved include the integrated control system, traveling block, winch, iron drill bit, chuck, slips, drilling platform robot, and second-level platform robot.

[0022] The main process is as follows: After the traveling block descends, the chuck clamps the drill pipe. Then, the winch controls the traveling block and the chuck to lift the drill string upwards. After lifting a certain distance (usually around 28 meters), the drill pipe is secured by the slips. At this point, the upper chuck, driven by the winch, needs to descend a certain distance to prevent the rotating drill pipe from causing the slips to rotate along with it when the drill operator uncouples the drill string. The drill operator then moves to the wellhead to uncouple the drill string. After uncoupling, the upper chuck, driven by the winch, is lifted a certain distance to separate the male and female threads of the drill string. Then, the drilling platform robot, the second-level platform robot, and the winch work together to store the disassembled drill string in the root box. This completes the lifting of one drill string. The subsequent steps are repeated as described above.

[0023] In one-click continuous drilling operations, when the automated equipment's iron driller uncouples at the wellhead, the unscrewing of the thread drives the drill rod upward.

[0024] Whether the number of uncoupling turns is insufficient or excessive, the upper and lower drill pipes cannot be separated. Moreover, after the drill pipes are uncoupled, if the force used to lift the upper drill pipe (male thread) and the axial deviation angle of the lower drill pipe (female thread) are too large, the male thread will be obliquely hooked on the female thread, making it impossible for the drill pipes to be separated.

[0025] The phenomenon where the upper and lower drill pipes cannot be separated due to various reasons after the aforementioned drill pipe has been uncoupled is generally referred to as "drill pipe with buckle" or "drill pipe with buckle".

[0026] Drill pipe buckling issues have a significant impact on drilling efficiency, especially in automated operations. Once buckling occurs, the tripping-out process must be stopped, and manual intervention is required to resolve the issue.

[0027] In related technologies, common methods to avoid drill pipe buckling issues include: 1. Adjusting the top drive guide rail or derrick inclination angle to ensure the lifting force and drill pipe axis are as aligned as possible; 2. Setting a sufficiently high precision number of drill pipe uncoupling turns for the drill operator, ensuring the drill pipe is just uncoupled, with no more and no less turns (precision of 0.1 turns or higher). However, during dual-clamp operation and workover rig operations, the drill pipe axis position frequently changes, making it difficult to ensure the lifting force and drill pipe axis are completely coaxial. Moreover, the exact number of turns required for just uncoupling may differ for each type of drill pipe, and even for each individual drill pipe, making it impossible to know the precise value before uncoupling. For example, for the same type of drill pipe, some require exactly 5.21 turns to untangle. If the number of turns to untangle is 5.28, then the drill pipe may travel a little more upwards because of the extra turns. However, at this time, the male and female threads of the drill pipe are not securely connected. Furthermore, due to the weight of the drill pipe, it may fall downwards, causing the male thread to embed slightly into the female thread, resulting in a selvage and potentially damaging the drill pipe.

[0028] According to an embodiment of this application, a drill pipe uncoupling control method is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0029] This application provides a drill pipe uncoupling control method. The drill pipe uncoupling device includes drill pipe, a steel drill bit, a top drive winch system, and a driller control system. The main tongs of the steel drill bit are equipped with a displacement sensor, and the top drive winch system is equipped with an encoder and a lifting clamp. The drill pipe includes a first drill pipe and a second drill pipe, which are connected by threads. The method is applied to the electronic controller of the driller control system. Figure 1 This is a flowchart of a drill pipe uncoupling control method according to an embodiment of this application, such as... Figure 1 As shown, the process includes the following steps: Step S101: Receive the first movement distance of the first drill rod during the uncoupling process, sent by the driller at a preset cycle.

[0030] Specifically, drill pipe refers to a steel pipe with threads at the tail, used to connect the drilling rig's surface equipment to the drilling equipment or bottom hole assembly located at the bottom of the well. It is divided into the first drill pipe (upper drill pipe) and the second drill pipe (lower drill pipe). A drill tong refers to specialized equipment used for connecting and disconnecting drill pipes and drill strings, consisting of a main tong, a back tong, and a rotary tong. A top drive winch system refers to the power unit used in oil drilling operations, which drives the top drive to perform lifting and lowering actions via a winch, directly driving the drill string rotation. The driller's control system, also known as the driller's console, can send control commands to the drill tong and the top drive winch system. The main tong is the core rotating tool of the drill tong, mainly used for connecting or disconnecting the drill string threads. A displacement sensor is a sensor installed on the main tong used to measure the distance the drill pipe has risen and fallen. An encoder is an instrument installed in the top drive winch system used to measure the height data of the top drive. A sling is a specialized tool in the top drive winch system used to suspend the drill pipe. The first drill pipe refers to the upper drill pipe among the drill pipes to be disconnected. The second drill pipe refers to the lower drill pipe in the drill pipe to be uncoupled. The first travel distance refers to the distance the first drill pipe rises during the uncoupling process.

[0031] In one possible implementation, during the uncoupling process, a displacement sensor installed on the driller's main tongs measures the rising distance of the first drill rod as the first moving distance, and sends the first moving distance to the driller's control system at preset intervals, and the driller's control system receives the first moving distance.

[0032] Step S102: Based on the first moving distance, send a first control command to the top drive winch system to control the hoist to be lifted along with the first drill pipe.

[0033] Specifically, the first control command refers to the command to control the top drive winch system to raise the height of the jack. The driller's control system uses the first movement distance of the first drill pipe during the uncoupling process to send the first control command to the top drive winch system to raise the height of the jack, so that the jack rises synchronously with the height of the first drill pipe.

[0034] It should be noted that the lifting clamp is part of the top drive in the top drive winch system and is used to lift the drill pipe. There is a gap between the drill pipe coupling and the lifting clamp, that is, there is a gap between the bottom of the female thread end of the upper drill pipe and the lifting clamp, and the female thread end of the upper drill pipe does not bear any force.

[0035] Step S103: Receive the lifting height of the hoist sent by the top drive winch system, and calculate the height difference between the cumulative moving distance of the first drill rod and the overall lifting height of the hoist. If the height difference is less than a preset height threshold, send a target instruction to the iron driller to unload the first drill rod from the second drill rod. The cumulative moving distance indicates the sum of the first moving distance during the uncoupling process, and the overall lifting height indicates the sum of the lifting height during the uncoupling process.

[0036] Specifically, the target instruction refers to the instruction to detach the first drill pipe from the second drill pipe. The cumulative travel distance refers to the sum of the first travel distances generated by the first drill pipe in all cycles during the uncoupling process. The overall lifting height refers to the sum of the lifting heights generated in all cycles during the uncoupling process. The driller's control system receives the lifting height of the chuck from the top drive winch system, calculates the height difference between the cumulative travel distance of the first drill pipe and the overall lifting height of the chuck, and performs further processing based on this height difference. If this height difference is less than a preset threshold, it indicates that the actual lifting height of the chuck is close to the first travel distance of the first drill pipe, meaning the chuck has provided a safe uncoupling height for the first drill pipe, thus triggering the target instruction, i.e., sending the instruction to the driller to detach the first drill pipe from the second drill pipe. The first and second drill pipes are then uncoupled.

[0037] The drill pipe uncoupling control method provided in this embodiment includes a drill pipe, a driller, a top drive winch system, and a driller control system. The driller's main tongs are equipped with a displacement sensor to facilitate the acquisition of the drill pipe's lifting distance. The top drive winch system is equipped with an encoder and a lifting clamp to facilitate the acquisition of the drill pipe's lifting height. The drill pipe includes a first drill pipe and a second drill pipe, which are connected by threads. The method is applied to the driller control system and includes: receiving a first movement distance of the first drill pipe during the uncoupling process sent by the driller at a preset period, thus obtaining the movement distance of the drill pipe during the uncoupling process; and sending a first control command to the top drive winch system based on the first movement distance to control the drill pipe. The lifting chuck rises in sync with the first drill pipe, maintaining its position and moving in sync with the drill pipe's ascent. It receives the lifting height from the top drive winch system and calculates the height difference between the cumulative movement distance of the first drill pipe and the overall lifting height of the chuck. If this difference is less than a preset height threshold, it sends a target instruction to the driller to detach the first drill pipe from the second drill pipe, ensuring stable contact between the chuck and the first drill pipe coupling. This lifts and supports the first drill pipe, maintaining its current height after detachment and preventing it from falling into the second drill pipe's coupling, thus resolving the coupling issue and enabling smooth uncoupling of drill pipes, improving the efficiency of oil drilling operations.

[0038] In one possible implementation, before receiving the first distance the first drill rod, sent by the driller at a preset cycle, has traveled during the uncoupling process, the method further includes: Step a1: Send a descent command to the top drive winch system. The descent command is used to lower the first drill pipe by a preset distance.

[0039] Specifically, the descent command refers to the instruction sent by the driller's control system to the top drive winch system to lower the first drill pipe a preset distance. Before the iron driller begins unhooking, the top drive winch system lowers the first drill pipe, thus reserving space for the iron driller to raise the first drill pipe during the unhooking process.

[0040] Step a2: Send the start unhooking command to the iron drill operator.

[0041] Specifically, the start uncoupling command is an instruction sent by the driller's control system to the iron driller to begin rotating the first drill pipe in order to initiate uncoupling.

[0042] In this implementation, after the first drill pipe is lowered by the top drive winch system, a command is sent to the drill operator to start uncoupling, providing a safe environment for uncoupling and preventing the first drill pipe from being blocked by the top drive during uncoupling, which would affect the normal uncoupling.

[0043] This application provides a drill pipe uncoupling control method. The drill pipe uncoupling device includes a drill pipe, a steel drill bit, a top drive winch system, and a driller control system. The main tongs of the steel drill bit are equipped with a displacement sensor, and the top drive winch system is equipped with an encoder and a lifting clamp. The drill pipe includes a first drill pipe and a second drill pipe, which are connected by threads. The method is applied to the controller of the steel drill bit. Figure 2 This is a flowchart of another drill pipe uncoupling control method according to an embodiment of this application, such as... Figure 2 As shown, the process includes the following steps: Step S201: Receive the start uncoupling command sent by the driller's control system.

[0044] Specifically, the driller receives the start uncoupling command from the driller's control system and begins uncoupling preparation.

[0045] In step S202, in response to the execution of the start unhooking command, the displacement sensor is controlled to monitor the first movement distance of the first drill pipe as it rises, and the first movement distance is sent to the driller's control system at a preset period.

[0046] Specifically, in response to the start uncoupling command, the driller uncouples the first and second drill pipes. The male thread at the lower end of the first drill pipe is gradually uncoupled from the female thread at the upper end of the second drill pipe until it has moved a first distance, indicating that it is about to be uncoupled. Simultaneously with uncoupling, the displacement sensor deployed in the driller's main tongs monitors the first distance the first drill pipe has moved and sends this first distance to the driller's control system.

[0047] In step S203, in response to the instruction to detach the first drill pipe from the second drill pipe, the main tong is released to complete the uncoupling.

[0048] Specifically, when the driller's control system detects that the first moving distance and the lifting height of the chuck are less than a preset threshold, or when they are equal, the control system recognizes that this is the opportune time to uncouple the first drill pipe from the second drill pipe. It then sends a uncoupling command to the drill operator, thereby uncoupling the first drill pipe from the second drill pipe. In response to this command, the drill operator releases the master tongs to complete the uncoupling of the first and second drill pipes. No hooking or buckling occurs.

[0049] Using the method in this embodiment, when a drill operator receives a start uncoupling command for a drill pipe uncoupling task, they perform the uncoupling operation and monitor the first distance the first drill pipe travels during the uncoupling process. When the driller's control system confirms that the uncoupling conditions have been met, it sends an uncoupling command, controlling the drill operator to release the master tongs to complete the uncoupling. This avoids the occurrence of hooking or tangling, thus improving the operational efficiency of oil drilling.

[0050] This application provides a drill pipe uncoupling control method. The drill pipe uncoupling device includes a drill pipe, a steel drill bit, a top drive winch system, and a driller control system. The main tongs of the steel drill bit are equipped with a displacement sensor, and the top drive winch system is equipped with an encoder and a lifting clamp. The drill pipe includes a first drill pipe and a second drill pipe, which are connected by threads. The method is applied to the controller of the top drive winch system. Figure 3 This is a flowchart of another drill pipe uncoupling control method according to an embodiment of this application, as shown below. Figure 3 As shown, the process includes the following steps: Step S301: Receive the descent command sent by the driller's control system.

[0051] Specifically, before controlling the iron driller to uncouple, the driller's control system first ensures the safety and reliability of the uncoupling environment, and therefore sends a descent command to the top drive winch system, which receives the descent command from the driller's control system.

[0052] In step S302, in response to the descent command, the first drill pipe is driven to descend a preset distance.

[0053] Specifically, after the top drive winch system receives the descent command sent by the driller's control system, it responds to the descent command by driving the first drill pipe down a preset distance through the top drive and the jack, in preparation for the start of uncoupling.

[0054] Step S303: Receive the first control command sent by the driller's control system to raise the height of the jack, record the lifting height of the jack through the encoder, and send the lifting height to the driller's control system.

[0055] Specifically, after determining the lifting height of the jack, the driller's control system sends a first control command to the top drive winch system. Upon receiving this first control command, the top drive winch system controls the top drive to lift the jack to the required height. Simultaneously, an encoder records the lifting height of the jack in real time and synchronizes it to the driller's control system.

[0056] In this embodiment, the top drive winch system, upon receiving a descent command from the driller's control system for a drill pipe uncoupling task, lowers the first drill pipe a preset distance. This provides a safe space for the first drill pipe to rise during the uncoupling process, preventing the chuck or top drive from restricting its ascent and thus affecting the normal uncoupling process. Furthermore, upon receiving a first control command from the driller's control line system to raise the chuck, the encoder records the height of the chuck as feedback for the top drive winch system's movement, providing a reliable numerical reference for the rising height to the driller's control system, ensuring the chuck is raised to the height corresponding to the first moving distance. This provides stable fixation for the uncoupling of the first drill pipe, ensuring that the first drill pipe will not fall back into the female thread of the second drill pipe due to its own weight after uncoupling, causing entanglement or buckling. This contributes to improving the operational efficiency of oil drilling.

[0057] This application provides a drill pipe uncoupling control system, such as Figure 4 As shown, the drill pipe shackle control system includes a drill pipe, a steel driller, a top drive winch system, and a driller control system. The main tongs of the steel driller are equipped with a displacement sensor, the top drive winch system is equipped with an encoder and a lifting clamp, and the drill pipe includes a first drill pipe and a second drill pipe, which are connected by threads. The driller control system sends a descent command to the top drive winch system, which is used to lower the first drill pipe by a preset distance. The driller's control system sends a start unhooking command to the iron driller; The drill operator receives the instruction to begin unhooking; In response to the start uncoupling command, the driller controls the displacement sensor to monitor the first movement distance of the first drill pipe as it rises, and sends the first movement distance to the driller's control system at a preset cycle. The driller's control system receives the first travel distance; The driller control system sends a first control command to the top drive winch system based on the first travel distance to control the hoist to be lifted along with the first drill pipe; The top drive winch system receives and executes the first control command, and records the lifting height of the hoist via an encoder, sending the lifting height to the driller's control system; The driller control system receives the lifting height of the jack sent by the top drive winch system and calculates the height difference between the cumulative moving distance of the first drill pipe and the overall lifting height of the jack. If the height difference is less than the preset height threshold, it sends a target instruction to the driller to unload the first drill pipe from the second drill pipe. The cumulative moving distance indicates the sum of the first moving distance during the uncoupling process, and the overall lifting height indicates the sum of the lifting height during the uncoupling process. The drill rig receives the target instruction; The driller responds to the target instruction by releasing the main clamp to complete the uncoupling.

[0058] This drill pipe uncoupling control system organically coordinates the drill pipe, the iron drill operator, the top drive winch system, and the driller's control system. The driller's control system issues the uncoupling initiation command and determines the uncoupling conditions. When the uncoupling conditions are met, the iron drill operator begins uncoupling the first drill pipe, and the top drive winch system records the lifting height of the hoisting chuck to match the rising height of the first drill pipe during uncoupling. When this rising height and the hoisting height approach a preset threshold, the driller's control system sends a target command to the iron drill operator, who then uncouples the first and second drill pipes. This ensures smooth uncoupling of the drill pipe, avoiding anomalies such as tangling and slippage, thereby improving the operational efficiency of oil drilling.

[0059] Figure 5 This is a flowchart illustrating another drill pipe uncoupling method according to an embodiment of this application. Figure 5 As shown, during the uncoupling of the drill pipe by the drill operator, a safe clearance △X (controlled at approximately 5mm) should be maintained between the chuck and the drill pipe coupling; the height of the chuck is indirectly measured using a winch drum encoder; and the drill pipe is uncoupled through the following steps: 1. When the driller unties the first drill rod, the main tongs move upwards together. A displacement sensor is installed on the driller's main tongs to synchronously detect the upward distance. .

[0060] 2. The drill operator moved the first drill rod upwards. The data is transmitted to the driller's control system, which then synchronously controls the top drive winch system to move upwards. ; 3. After the driller unties the coupling, the first drill rod falls a small distance △X due to its own weight. At this time, the lifting clamp and the first drill rod coupling come into contact. The lifting clamp is subjected to force and lifts the first drill rod, preventing it from falling further.

[0061] 4. After the buckle is removed, the first drill pipe can only descend a small distance △X under the lifting of the hoist. The male buckle of the first drill pipe cannot fall back into the female buckle, thus solving the buckle problem.
