Description

Technical Field

[0001] This application relates to the field of drilling process control technology, and in particular to a drilling rig power linkage control system adapted to multiple drilling processes. Background Technology

[0002] In the field of power control technology for drilling rigs used in water well and coalbed methane development, the continuous development of the industry has placed higher demands on the performance and applicability of drilling rigs. The emergence of multiple drilling processes necessitates that drilling rigs be capable of adapting to different processes to meet diverse operational needs. This not only helps improve drilling efficiency but also expands the application range of drilling rigs, bringing new opportunities and challenges to the development of related fields. Before this technical solution, for drilling rigs adaptable to multiple drilling processes, such as the SPS2000, when switching between different processes was required, the usual method was to manually adjust the parameters of each working component individually. Specifically, for parameters such as rotary table speed, winch lifting speed, and water brake damping, which have different requirements for different processes, operators needed to manually set and adjust them one by one. This method was widely used in practice and was the conventional means of solving the problem of adjusting process switching parameters at that time. However, this conventional method of existing technology has obvious drawbacks. Because it requires manual adjustment of the parameters of each component, the operation process is very cumbersome, and the parameter matching accuracy is low. This leads to poor process switching efficiency when switching between multiple drilling processes and also increases equipment wear and tear.

[0003] Therefore, in view of the above situation, there is an urgent need to develop a drilling rig power linkage control system that is compatible with multiple drilling processes, so as to overcome the shortcomings in current practical applications. Summary of the Invention

[0027] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. 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.

[0028] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0030] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0031] The present invention provides the following embodiments: Example 1

[0032] like Figure 1 As shown in the embodiment of this application, the drilling rig power linkage control system adapted to multiple drilling processes includes a process selection unit, a linkage control module, and a parameter pre-storage unit. The process selection unit is used to receive the selection command of the target drilling process. The parameter pre-storage unit stores the rotary table speed, winch lifting speed, and water brake damping parameters corresponding to at least two drilling processes. The linkage control module is connected to the process selection unit, the parameter pre-storage unit, and the drilling rig's power unit, rotary table drive unit, winch, and water brake. The linkage control module responds to the selection command, retrieves the corresponding process parameters, and synchronously outputs them to each execution component. This achieves one-click parameter matching for multiple drilling processes, simplifies the operation process, ensures accurate adaptation of parameters for each component, reduces equipment wear, and improves drilling stability. This is because after the target process is selected through the process selection unit, the linkage control module can quickly call up the accurate pre-stored parameters and simultaneously control each execution component, avoiding the tediousness and errors of manual parameter adjustment.

[0033] Specifically, the process selection unit includes a touchscreen display, which can be a common LCD screen with a dustproof sealing layer, such as a silicone sealant, to effectively prevent dust from entering and affecting operation. The touchscreen interface features independent process selection buttons and a parameter display area. The independent process selection buttons can be virtual touch buttons, with different icons or text labels corresponding to processes such as air down-the-hole hammer, roller cone, and conventional drilling. The parameter display area can display parameters such as the turntable speed, winch lifting speed, and water brake damping corresponding to the currently selected process in real time. Alternatively, the process selection unit can use physical selection switches, such as rotary switches or DIP switches, which can also receive target drilling process selection commands.

[0034] Specifically, the linkage control module includes a programmable logic controller (PLC), a commonly used industrial control device characterized by high reliability and flexible programming. The PLC forms a closed-loop control circuit with the power unit, rotary table drive unit, winch, and water brake via an electrical interface, such as a common serial port or Ethernet interface. Within this closed-loop control circuit, the PLC can acquire real-time operating status information of each actuator and adjust accordingly based on pre-stored parameters, ensuring that each component operates according to the target process requirements. The connection between the linkage control module and the power unit uses a fiber optic communication bus. Fiber optic communication buses offer advantages such as high transmission speed and strong anti-interference capabilities, and support dual redundant signal transmission. When one signal transmission line fails, the other line can continue to operate, ensuring system stability. The linkage control module incorporates a speed-pressure co-calculation module. This module, implemented using software algorithms, correlates the output ratio of rotary table speed and water brake damping parameters in real time. Based on different drilling processes and actual working conditions, it dynamically adjusts the ratio to improve drilling efficiency and stability.

[0035] Specifically, the parameter pre-storage unit uses a database structure to store process parameters. The database can be a relational database, such as MySQL, or a non-relational database, such as MongoDB. The database contains independent parameter sets for the air down-the-hole hammer process group, the roller cone process group, and the conventional drilling process group. Each parameter set stores parameters such as the rotary table speed, winch lifting speed, and water brake damping for the corresponding process. The parameter pre-storage unit is equipped with a remote update interface, which can be a wireless communication module, such as a Wi-Fi module or a 4G / 5G module. This interface supports receiving process parameter packets sent by external terminals via a wireless network and replacing the original stored parameters, facilitating parameter updates and maintenance of the system.

[0036] This embodiment also includes a parameter correction unit, which connects the linkage control module to the sensing elements of each actuator. These sensing elements can be speed sensors, pressure sensors, etc., used to collect the actual operating parameters of the actuators in real time. The correction unit feeds back the collected actual parameters to the linkage control module for compensation and correction, ensuring that the operating parameters of each actuator accurately match the requirements of the target process. The water brake is connected to the linkage control module via an electronic regulating valve. The electronic regulating valve includes an electromagnetic proportional valve and a mechanical limit mechanism. The electromagnetic proportional valve can precisely adjust the damping of the water brake according to the signal from the linkage control module, and the mechanical limit mechanism sets the physical adjustment range of the damping parameter to prevent damage to the equipment caused by excessive or insufficient damping. A transmission ratio converter is installed between the linkage control module and the winch. The converter can be a mechanical transmission structure or an electronic speed control device, adjusting the drum rotation diameter according to the target process parameters to change the lifting speed and meet the requirements of different drilling processes for the winch's lifting speed.

[0037] The implementation principle of this embodiment is as follows: Through the coordinated operation of the process selection unit, the linkage control module, and the parameter pre-storage unit, one-click parameter matching for multiple drilling processes is achieved. Operators only need to select the target process in the process selection unit, and the linkage control module automatically calls the pre-stored parameters to synchronously regulate the operating status of each execution component. The parameter correction unit further improves the accuracy of parameter matching, reduces equipment wear, and enhances drilling stability. Compared with existing technologies, this embodiment simplifies the operation process, improves process switching efficiency, and provides a more efficient and reliable solution for multi-process operations of drilling rigs.

[0038] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
