Description

Technical Field

[0001] This invention relates to the field of drilling fluid solid phase control technology, and in particular to a control method, device, equipment, medium and product for a drilling vibrating screen. Background Technology

[0002] Drilling vibrating screens are the first and most critical solids control device in the solids control system (drilling fluid purification system) of oil and gas drilling operations. Their main function is to use vibration and sieving principles to separate larger solid particles (such as drill cuttings and sand) from the drilling fluid (mud) returning from the bottom of the well, thereby purifying the drilling fluid, ensuring its stable performance, improving drilling efficiency, and protecting downstream equipment. Traditional drilling vibrating screen control technology is relatively outdated, requiring manual inspection for mud leakage and adjustment. This manual adjustment and inspection mode requires a significant investment of manpower. Furthermore, manual inspections sometimes fail to detect mud leakage in time, resulting in drilling fluid loss and causing economic losses to the drilling team.

[0003] Currently, the intelligent control systems for drilling vibrating screens based on machine vision images that have been announced mostly use cameras to capture images of the screen surface at the vibrating screen outlet. The signal processor then performs image recognition and determines whether slurry leakage has occurred. If slurry leakage occurs, the controller adjusts the screen box tilt angle using the screen box tilt adjustment device.

[0004] The intelligent control system for drilling vibrating screens based on machine vision images requires hardware modification of the drilling vibrating screens and on-site deployment of corresponding hardware equipment. Due to the harsh working environment of drilling vibrating screens, not only is it necessary to use expensive, highly reliable, and high-performance equipment, but it is also necessary to frequently replace hardware equipment damaged by the harsh environment, resulting in excessively high costs for intelligent transformation and making it difficult to widely adopt.

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0029] It should be noted that the terms "first," "second," etc., used in this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0030] Figure 1A This is a flowchart illustrating a control method for a drilling vibrating screen according to an embodiment of the present invention. This embodiment is applicable to situations where the hardware of a drilling vibrating screen is modified for intelligent control. The method can be executed by a control device for the drilling vibrating screen, which can be implemented in hardware and / or software. This device can be configured in an electronic device with corresponding data processing capabilities, such as a primary edge computing device in an intelligent control system. Figure 1A As shown, the method includes:

[0031] S110. Based on the images captured by the camera facing the local drilling vibrating screen, determine the local control strategy for the screen mesh of the local drilling vibrating screen.

[0032] S120: Receive remote control strategy for the screen of the remote drilling vibrating screen sent from the edge computing device.

[0033] S130. Generate a new control strategy array for the current control cycle based on the local control strategy and the remote control strategy, and send the new control strategy array to the execution device through the I / O module.

[0034] The new control strategy array instructs the executing equipment to uniformly control the screens of both the local and remote drilling vibrating screens according to the new control strategy array. The primary edge computing device is used for slurry leakage risk detection and screen control of the local drilling vibrating screen, while the secondary edge computing device is used for slurry leakage risk detection and screen control of the remote drilling vibrating screen. The control strategy array contains the control strategy for each drilling vibrating screen, including both the local and remote drilling vibrating screens.

[0035] Specifically, such as Figure 1B As shown, the intelligent control system consists of cameras, (master / slave) edge computing devices, I / O modules, and execution devices. The local drilling vibratory screen is controlled by the master edge computing device, while the remote drilling vibratory screen is controlled by slave edge computing devices. Compared to traditional centralized servers, edge computing devices have limited computing power and cannot control all drilling vibratory screens on-site by a single device. Therefore, multiple edge computing devices (e.g., two) are deployed on-site, with each device controlling only a portion (e.g., three) of the drilling vibratory screens. One edge computing device is designated as the master, and the others as slaves. This type of edge computing device, with its limited computing power, is significantly cheaper than traditional centralized servers, greatly reducing initial deployment and subsequent maintenance costs.

[0036] For each drilling vibrating screen at the work site, a separate camera is deployed, facing the screen and capturing images of its interior. The main edge computing device and the slave edge computing devices have essentially the same functionality. The difference lies in that slave edge devices cannot communicate directly with the I / O module and must first send the generated remote control strategy to the main edge computing device via UDP communication. This is because the I / O module has limited bandwidth. If each slave edge computing device communicates directly with the I / O module, it would put significant pressure on the I / O module's bandwidth, making it impossible to use low-cost, low-bandwidth I / O modules and forcing the use of high-cost, high-bandwidth I / O modules.

[0037] Using a preset time length (e.g., 500ms) as a control cycle, at the end of each control cycle, the main edge computing device summarizes the local control policies it generated in the current control cycle and the remote control policies sent by each slave edge computing device in the current control cycle, and generates a one-dimensional new control policy array.

[0038] For example, at the end of the current control cycle, the local control strategies for the three local drilling vibrating screens controlled by the main edge computing device are up, up, and hold still; the remote control strategies for the three remote drilling vibrating screens controlled by the slave edge computing device are down, down, and up. The resulting new control strategy array is [up, up, hold still, down, down, up].

[0039] The main edge computing device sends the new control strategy array thread to the I / O module in digital signal form via the Modbus RTU communication thread. The I / O module then forwards the new control strategy array to the execution device. The execution device controls each drilling vibrating screen to raise, lower, or keep its screen stationary according to the control strategy of each drilling vibrating screen in the new control strategy array.

[0040] This invention achieves intelligent control of the drilling vibrating screen through multiple distributed edge computing devices, which can significantly reduce the hardware costs of initial modification and subsequent maintenance compared to traditional intelligent transformation schemes.

[0041] Based on the above embodiments, optionally, the execution device is a hydraulic station, which is connected to the hydraulic cylinders in each drilling vibrating screen through hydraulic pipelines, and controls the rise and fall of the hydraulic cylinders through the inlet and outlet of hydraulic oil in the hydraulic pipelines; when the hydraulic cylinders in the drilling vibrating screen rise, they drive the screen of the drilling vibrating screen to rise, and when they fall, they drive the screen of the drilling vibrating screen to fall.

[0042] Specifically, the hydraulic cylinders of traditional drilling vibrating screens lack network connectivity, requiring hardware modifications to enable remote control of their lifting and lowering. Existing modifications often involve installing corresponding network modules and execution modules on each drilling vibrating screen. When there are a large number of drilling vibrating screens, the modification cost remains high. Therefore, this invention eliminates the need for network modules in the drilling vibrating screens. Instead, the hydraulic cylinders in each drilling vibrating screen are connected to a hydraulic station via hydraulic pipelines. The hydraulic station can then control the lifting and lowering of the hydraulic cylinders through the inflow and outflow of hydraulic oil in the pipelines, further reducing modification costs. Simultaneously, the drilling vibrating screen mesh is located above the hydraulic cylinders; the lifting of the hydraulic cylinders causes the drilling vibrating screen mesh to rise, and the lowering of the hydraulic cylinders causes the drilling vibrating screen mesh to fall.

[0043] A screen is typically equipped with two hydraulic cylinders, one on each side of the screen. These cylinders drive the screen to rise / fall, thereby indirectly adjusting the screen's front-to-back angle.

[0044] Based on the above embodiments, optionally, determining the local control strategy for the screen mesh of the local drilling vibrating screen based on the image captured by the camera facing the local drilling vibrating screen includes:

[0045] For each local drilling vibrating screen, image recognition is performed on the image captured by the camera facing the local drilling vibrating screen to obtain the mud line in the image;

[0046] Based on the relative positions of the mud line and the reference line in the image, a local control strategy is determined for the local drilling vibrating screen.

[0047] Specifically, refer to Figure 1C For images captured by the camera, the edge computing device sends the images to the AI ​​algorithm thread for image recognition, obtaining the mud lines in the images. The mud lines are then displayed in red on the corresponding images via the UI thread, and the reference lines are displayed in yellow. The relative positions of the mud lines and reference lines in the images are compared to determine the local control strategy for the local drilling vibrating screen.

[0048] Based on the above embodiments, optionally, the reference line includes a first reference line and a second reference line, wherein the height of the first reference line is greater than the height of the second reference line, and determining the local control strategy for the local drilling vibrating screen mesh based on the relative position of the mud line position and the reference line position in the image includes:

[0049] If the mud line is positioned below the second reference line in the image, then lifting the hydraulic cylinder is determined as the local control strategy for the local drilling vibrating screen.

[0050] If the mud line is positioned above the first reference line in the image, then lowering the hydraulic cylinder is determined as the local control strategy for the local drilling vibrating screen.

[0051] If the position of the mud line in the image is not lower than the second reference line and not higher than the first reference line, then keeping the hydraulic cylinder stationary is determined as the local control strategy for the local drilling vibrating screen.

[0052] For details, please refer to Figure 1C When the mud line is lower than the second reference line (i.e., the yellow line at the bottom of the image), it indicates that the screen height is too low and needs to be increased. Lifting the hydraulic cylinder is then determined as the appropriate control strategy.

[0053] When the mud line is higher than the first reference line (i.e., the yellow line at the top of the image), it indicates that the screen is too high and there is a risk of mud leakage. The screen needs to be lowered, and the hydraulic cylinder should be lowered as the appropriate control strategy.

[0054] When the mud line is positioned in the image at a level that is neither lower than the second reference line nor higher than the first reference line, it indicates that the height of the screen is just right and there is no need for adjustment. Keeping the hydraulic cylinder stationary is determined as the appropriate control strategy.

[0055] Figure 2This is a flowchart illustrating a control method for a drilling vibrating screen according to another embodiment of the present invention. This embodiment is an optimization and improvement based on the above embodiments. Figure 2 As shown, the method includes:

[0056] S210. Based on the images captured by the camera facing the local drilling vibrating screen, determine the local control strategy for the screen mesh of the local drilling vibrating screen.

[0057] S220: Receive remote control strategy for the screen of the remote drilling vibrating screen sent from the edge computing device.

[0058] S230. If there is an abnormal edge computing device that has not sent a remote control policy in the current control cycle, then the remote control policy sent by the abnormal edge computing device last time is reused as the remote control policy sent by the abnormal edge computing device in the current control cycle.

[0059] S240. Summarize the local control strategies and remote control strategies of the current control cycle to obtain the new control strategy array for the current control cycle.

[0060] Specifically, the working environment of drilling vibrating screens is harsh. Edge devices may malfunction due to network fluctuations, overheating, or other reasons, becoming abnormal edge computing devices that fail to send remote control policies at the end of the current control cycle. In this abnormal situation, the remote control policy issued by the abnormal edge computing device remains unchanged by default. The master edge computing device reads the previously sent remote control policy from the log and reuses it as the remote control policy sent by the abnormal edge computing device in the current control cycle. Based on this, a new control policy array for the current control cycle is generated.

[0061] S250. If the new control policy array is consistent with the previously sent historical control policy array, then the transmission of the new control policy array to the execution device via the I / O module is abandoned; if the new control policy array is inconsistent with the previously sent historical control policy array, then the new control policy array is transmitted to the execution device via the I / O module.

[0062] Specifically, the bandwidth of the I / O module is limited, and the main edge computing device cannot frequently send control policy arrays to it. Therefore, before sending a newly generated control policy array, the main edge computing device first compares the new control policy array with the previously sent historical control policy array to determine if they are completely identical. If they are completely identical, it means that continuing to send the new control policy array is meaningless, and the newly generated control policy array will not be sent, thus reducing the processing pressure on the I / O module. If they are not completely identical, it means that the control logic has changed; for example, a drilling vibrating screen has lowered to a suitable height and no longer needs to be lowered, requiring the I / O module to send a new control policy array to the execution device.

[0063] In this embodiment of the invention, a new control strategy array is only issued when the new control strategy array is inconsistent with the historical control strategy array, thereby reducing the processing pressure on the I / O module.
