[0026] Application Overview

[0027] At present, the improvement of the working efficiency of rotary drilling rigs is mainly concentrated in the piling process, which is usually divided into the following two categories. One is to propose a reasonable construction process based on specific working conditions, optimize the piling process, and improve the working efficiency of rotary drilling rigs; the other is to improve the piezoelectric hydraulic control system and improve the efficiency of compound motion.

[0028] The above-mentioned improvement methods are either targeted at specific working conditions or not very targeted, and cannot achieve a better efficiency improvement. In fact, the drilling stage of the piling process plays a key role in improving the construction efficiency of the rotary drilling rig. How to effectively improve the drilling efficiency is a problem that needs to be solved urgently.

[0029] In order to solve or improve the technical problem in the prior art that the drilling efficiency of a rotary drilling rig operation process cannot be effectively improved, the present application provides a drilling control method and device for a rotary drilling rig and a rotary drilling rig.

[0030] The drilling control method of the rotary drilling rig provided in the present application specifically includes the following steps: obtaining the operating data of the rotary drilling rig; determining the features to be optimized of the drilling efficiency based on the operating data and the drilling efficiency model of the rotary drilling rig; and controlling the drilling parameters of the rotary drilling rig based on the features to be optimized and the working condition information. This drilling control method of the rotary drilling rig optimizes the drilling stage of the rotary drilling rig, combines the operating data of the rotary drilling rig client under various working conditions, inputs the operating data into the drilling efficiency model, obtains the features to be optimized with a high correlation with the drilling efficiency optimization, controls the relevant drilling parameters of the rotary drilling rig operation process according to the features to be optimized, so as to achieve the purpose of improving the drilling efficiency, so as to effectively improve the drilling efficiency and operating efficiency of the rotary drilling rig under various working conditions, and has a wide range of application and high reliability.

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] Exemplary Methods

[0033] Figure 1 FIG. 1 is a flow chart of a method for controlling the drilling of a rotary drilling rig according to an embodiment of the present application. Figure 1 As shown, the drilling control method of the rotary drilling rig provided by the present application may specifically include the following steps:

[0034] Step 100: Acquire the operating data of the rotary drilling rig.

[0035] A rotary drilling rig is a comprehensive drilling rig that is often used in various construction projects. It can be applied to a variety of strata and has the characteristics of fast hole-making speed, less pollution, and strong mobility. It is suitable for foundation (pile foundation) construction in urban construction scenarios. Operation data refers to the relevant data recorded by the client during and after the operation of the rotary drilling rig, including but not limited to parameter data such as the power head speed and the power head torque. It is not difficult to understand that the operation process of the rotary drilling rig will generate a large amount of operation data on the client. These operation data include the operating parameters of the rotary drilling rig under different working conditions. Mining, collecting and analyzing such data can provide an effective data basis for improving the operating efficiency of the subsequent operation process of the rotary drilling rig. In addition, mining the drilling efficiency optimization strategy of the rotary drilling rig based on the client's operation data can make the optimization strategy more customized and more in line with the user's usage habits.

[0036] Step 200: Determine the features to be optimized for drilling efficiency based on the operation data and the drilling efficiency model of the rotary drilling rig.

[0037] The drilling efficiency model is obtained after training the initial digital model based on the operating data of the rotary drilling rig, and is used to predict the drilling efficiency of the rotary drilling rig. After the operating data is input into this drilling efficiency model, the drilling efficiency model corresponds to the output drilling efficiency range. More importantly, the feature importance of this drilling efficiency model is combined to screen the features with a high correlation with the drilling efficiency. The above features are the type features of the input operating data. For example, if the pressurization method and / or the power head speed are features with a high correlation with the drilling efficiency, it means that adaptive improvements to these two features can effectively improve the drilling efficiency. The features to be optimized refer to one or more features with a high correlation with the drilling efficiency. After the features to be optimized are determined, the drilling parameters related to the features to be optimized can be optimized and improved in a targeted manner, which can effectively improve the drilling efficiency of the rotary drilling rig.

[0038] Step 300: Control the drilling parameters of the rotary drilling rig based on the features to be optimized and the working condition information.

[0039] Working condition information refers to the operating conditions of the rotary drilling rig, such as the type of formation, the size and model of the drill bucket, etc. It is not difficult to understand that the features to be optimized under different working conditions may be the same or different. Controlling and adjusting the drilling parameters of the rotary drilling rig for the current working conditions and the features to be optimized under the current working conditions can greatly improve the drilling efficiency. In addition, when the working conditions of the rotary drilling rig change, the corresponding features to be optimized also change accordingly. At this time, it is sufficient to control and adjust the drilling parameters related to the current features to be optimized, which improves the drilling efficiency while expanding the scope of application scenarios of this control method.

[0040] In one possible implementation, Figure 2FIG. 2 is a flow chart of a drilling control method for a rotary drilling rig provided by another embodiment of the present application. Figure 2 As shown, step 200 (determining the features to be optimized for drilling efficiency based on the operating data and the drilling efficiency model of the rotary drilling rig) may further include the following steps:

[0041] Step 210: Based on the operation data, drilling-related data of the drilling status of the rotary drilling rig is obtained.

[0042] Drilling related data refers to the data related to the drilling stage in the operation data. It is not difficult to understand that the operation process of the rotary drilling rig includes multiple stages, such as hole opening, drilling, slag removal and hole formation. Therefore, it is necessary to filter out the operation data related to the drilling stage from the numerous operation data as drilling related data. Analyzing and processing the drilling related data obtained after screening can effectively improve the drilling efficiency, thereby reducing the amount of data processing and improving the efficiency of data processing.

[0043] Step 220: Based on the drilling-related data and the drilling efficiency model, feature importance screening of the drilling efficiency model is performed to generate feature screening results.

[0044] Feature importance is also called feature importance. Feature importance is a method of scoring the input features of a prediction model. This method reveals the relative importance of each feature when making a prediction. Feature importance scores can be calculated for problems involving predicting numerical values ​​(called regression) and problems involving predicting class labels (called classification). Relative scores can highlight which features may be most relevant to the target, and vice versa. The feature screening result refers to the relative score of the above features. Features with higher relative scores indicate a higher correlation with drilling efficiency. Conversely, features with lower relative scores indicate a higher possibility of being irrelevant or weakly correlated with drilling efficiency. Input features include drilling-related data in the above steps, such as pressurization method and power head speed.

[0045] Step 230: Based on the feature screening results, determine the features to be optimized for drilling efficiency.

[0046] Through the feature screening results, we can know the degree of correlation between each feature in the input model and the improvement of drilling efficiency. Features with higher scores indicate that they are more correlated with drilling efficiency and can be used as features to be optimized for drilling efficiency. Optimizing such features accordingly can effectively improve drilling efficiency. On the contrary, features with lower scores indicate that they are weakly correlated with drilling efficiency or are irrelevant to drilling efficiency. Optimizing such features will have little effect on improving drilling efficiency. In other words, accurately determining the features to be optimized can make the improvement of drilling efficiency more obvious and effective, and make the process of finding the optimization point faster, reducing time waste. It is not difficult to understand that there can be one or more features to be optimized, and the specific judgment should be based on the score of the feature screening results.

[0047] Specifically, in one embodiment, Figure 3 FIG. 2 is a flow chart of a method for determining features to be optimized in a drilling control method for a rotary drilling rig provided by another embodiment of the present application. Figure 3 As shown, step 230 (determining the features to be optimized for drilling efficiency based on the feature screening results) may further include the following steps:

[0048] Step 2301: Based on the feature screening results, determine the key features that affect the drilling efficiency.

[0049] The key feature refers to the feature with the highest score in the feature importance screening process, which can also be understood as the feature with the highest correlation with drilling efficiency optimization. When the optimization conditions are limited, determining the key features can save optimization steps and simplify the optimization strategy without causing too much impact on the optimization effect.

[0050] Step 2302: Use key features as features to be optimized.

[0051] Taking the features most relevant to drilling efficiency as the features to be optimized can make the optimization process of drilling efficiency more effective and targeted.

[0052] In another possible implementation, Figure 2 As shown, step 300 (controlling the drilling parameters of the rotary drilling rig based on the characteristics to be optimized and the working condition information) may further include the following steps:

[0053] Step 310: Acquire operating condition data, where the operating condition data includes formation type data and / or drill bucket parameters and / or power head rotation speed.

[0054] The operating condition data is used to reflect the operating condition of the rotary drilling rig, including but not limited to formation type data, drill bucket parameters and power head speed. Obtaining such data is helpful for analyzing and judging the operating condition of the rotary drilling rig, and then specifying a reasonable drilling strategy.

[0055] Step 320: Determine operating condition information based on the operating condition data.

[0056] Working condition information refers to the working condition type of the rotary drilling rig. According to the working condition data of the rotary drilling rig, such as the formation type is one of silt, clay, granite and limestone, the specific values ​​of the drill bucket parameters include the model and size of the drill bucket, such as the drill bucket is a 1.8m sand bucket or a 1.4m barrel drill. Different working conditions correspond to different or the same formation types, drill bucket parameters, and power head speeds. It is not difficult to understand that under different working conditions, the same feature to be optimized may also have different optimization methods, so it is necessary to confirm the working condition information first in order to achieve the purpose of accurately and effectively improving and optimizing the drilling efficiency.

[0057] Step 330: Based on the features to be optimized and the working condition information, the drilling parameters under each working condition in the working condition information are obtained one by one.

[0058] Combined with the working condition information, select the optimization method of the feature to be optimized under the working condition. For example, if the feature to be optimized is the power head speed, the working condition information includes that the formation type is granite and the drill bucket is a 1.4m barrel drill. Under this restriction, the optimal power head speed is calculated and used as the power head speed under this working condition, thereby effectively improving the drilling efficiency. In addition, after the optimal power head speed for a certain working condition is determined, the power head speeds for other working conditions are determined separately for other working conditions, that is, the optimal power head speeds for all working conditions are calculated and the data is saved for subsequent use.

[0059] Step 340: Based on the drilling parameters, control the drilling process of the rotary drilling rig.

[0060] Based on the optimal parameters under different working conditions determined in the above steps, such as the power head speed, the operator of the rotary drilling rig can manually or the control system can automatically select the optimal power head speed according to the working conditions, so that the rotary drilling rig can drill efficiently under different working conditions, thereby improving the overall operating efficiency of the rotary drilling rig.

[0061] It is worth mentioning that after the characteristics to be optimized and the optimal drilling parameters are determined, the control device can automatically control the drilling process of the rotary drilling rig, or output the optimal drilling parameters to the operator of the rotary drilling rig for manual control by the operator. That is, the specific control method should depend on the specific application scenario, and this application does not make further limitations on this.

[0062] Optionally, in one embodiment, Figure 4 FIG. 2 is a flow chart of a method for controlling drilling parameters in a method for controlling drilling parameters of a rotary drilling rig provided by another embodiment of the present application. Figure 4As shown, when the feature to be optimized is the pressurization mode, the above step 330 (obtaining the drilling parameters under each working condition in the working condition information one by one based on the feature to be optimized and the working condition information) may specifically include the following steps:

[0063] Step 3301: Analyze the relationship between the pressurization method and the drilling speed, and generate analysis results.

[0064] The pressurization methods include the large chamber pressure of the pressurized oil cylinder and the small chamber pressure of the pressurized oil cylinder. The size of the drilling speed and the upward or downward trend under different pressurization methods are analyzed to obtain the relationship between the pressurization method and the drilling speed, and the analysis results are obtained, which include the optimal pressurization method.

[0065] Step 3302: Based on the analysis results, determine the optimal pressurization method that meets the current working conditions.

[0066] Only by determining the optimal pressurization method can a strategy for improving drilling efficiency be formulated based on this method.

[0067] Step 3303: Use the pressurization parameters in the optimal pressurization method as the drilling parameters under the current working conditions.

[0068] Using the pressurization parameters in the optimal pressurization method as the drilling parameters under the current working conditions can maximize the drilling speed, thereby effectively improving the drilling efficiency.

[0069] Through the above steps, the calculation and output of the optimal pressurization method under any of the multiple working conditions are completed. After that, the optimal pressurization method should be calculated for other working conditions, such as whether the working conditions are fully covered. If they are fully covered, the relevant drilling parameters are controlled or the drilling parameters are output. If they are not fully covered, the calculation of other working conditions is continued. It is not difficult to understand that the calculation process is the same as step 3301 to step 3303 until all working conditions are fully covered. This can facilitate the operator or control system in the actual application process to select the optimal pressurization method according to the working conditions, thereby improving the wide application of this control method.

[0070] In one possible implementation, Figure 2 As shown, step 100 may specifically include the following steps:

[0071] Step 110: Obtaining the power head rotation speed and / or power head torque and / or pressurized cylinder pressure of the rotary drilling rig during operation of the same amount.

[0072] The power head speed and / or power head torque and / or pressurized cylinder pressure during the operation of the rotary drilling rig are the operating data of the rotary drilling rig under multiple working conditions. It is not difficult to understand that the frequency of different operating data appearing with the operating time of the rotary drilling rig is not necessarily the same. Therefore, the collection frequency of different data is also different when collecting operating data. For example, some data can be collected once every 0.1 milliseconds, while some data can be collected once every 0.3 milliseconds. In order to improve the reliability of the operating data analysis process, it is more reliable and effective to analyze under the premise that the number of different types of operating data is consistent. Therefore, when obtaining operating data, the number of different operating data, such as power head speed, power head torque, and pressurized cylinder pressure, is unified, which is helpful for the subsequent data input model and data analysis process.

[0073] Specifically, in one embodiment, Figure 5 FIG. 2 is a flow chart of a drilling efficiency model training method in a drilling control method of a rotary drilling rig provided by another embodiment of the present application. Figure 5 As shown, before step 200 (determining the characteristics to be optimized for drilling efficiency based on the operating data and the drilling efficiency model of the rotary drilling rig), the drilling control method of the rotary drilling rig may further include the following steps:

[0074] Step 101: Based on the running data, train the initial model and obtain the mean absolute percentage error of the test set of the initial model.

[0075] In order to improve the accuracy of the confirmation of the features to be optimized, before confirming the features to be optimized of the rotary drilling rig, the initial model is first trained based on the historical operation data, preferably using the drilling-related data in the operation data as the training data, and adding data label information to the drilling efficiency interval of the rotary drilling rig under the historical operation data. During the training process of the initial model, the mean absolute percentage error (MAPE) of the test set is constantly checked to determine whether the initial model meets the usage conditions in combination with the mean absolute percentage error.

[0076] Step 102: When the mean absolute percentage error is less than or equal to a preset target value, determine to use the initial model as the drilling efficiency model.

[0077] The preset target value is a value preset by the system. When the mean absolute percentage error of the initial model is less than or equal to the preset target value, it means that the initial model has been trained and can be used to determine the features to be optimized.

[0078] Optional, such as Figure 5As shown, with the continuous use of the rotary drilling rig and the continuous replacement of operators, the availability of key features and drilling efficiency models may change. In addition, this process will further generate a large amount of operating data. Therefore, after step 102 (when the mean absolute percentage error is less than or equal to the preset standard value, determine to use the initial model as the drilling efficiency model), the drilling control method of the rotary drilling rig may also include the following steps:

[0079] Step 103: When the amount of the operating data is greater than or equal to a preset quantity threshold, a drilling efficiency model is trained based on the operating data to obtain a mean absolute percentage error of a test set of the drilling efficiency model.

[0080] The preset quantity threshold is the data volume value set by the system according to historical usage, which may include, for example, the specific amount of data or the usage time of the rotary drilling rig. That is, when the collected operating data exceeds a certain amount, a new round of training can be carried out on the drilling efficiency model, thereby forming a drilling efficiency model that is more suitable for the current rotary drilling rig and the current operator, ensuring the accuracy of the drilling efficiency model in determining the features to be optimized, thereby ensuring the effective improvement of the drilling efficiency.

[0081] Step 104: When the mean absolute percentage error is less than or equal to the preset target value, the drilling efficiency model training is completed.

[0082] Similarly, when the average absolute percentage of the test set of the drilling efficiency model during the training process meets the preset standard value, the model training can be considered complete and can continue to be used to confirm the features to be optimized. In this way, the drilling efficiency model and its feature importance can be updated in real time based on the continuous accumulation of client operation data, which facilitates real-time mining of optimization strategies and ensures the timeliness of strategies.

[0083] Corresponding to the above-mentioned drilling control method of the rotary drilling rig, the embodiment of the present application further discloses a drilling control device of the rotary drilling rig, Figure 6 FIG. 1 is a structural block diagram of a drilling control device for a rotary drilling rig provided in an embodiment of the present application.

Since this control device includes the data acquisition module 101, the feature determination module 102 and the parameter control module 103, it can perform the following drilling control method of the rotary drilling rig: acquire the operating data of the rotary drilling rig; determine the features to be optimized of the drilling efficiency based on the operating data and the drilling efficiency model of the rotary drilling rig; and control the drilling parameters of the rotary drilling rig based on the features to be optimized and the working condition information. The drilling control device 100 of the rotary drilling rig is optimized for the drilling stage of the rotary drilling rig. The operating data of the rotary drilling rig client under various working conditions is combined, and the operating data is input into the drilling efficiency model to obtain features to be optimized that have a high correlation with the optimization of the drilling efficiency. Based on the features to be optimized, the relevant drilling parameters of the operating process of the rotary drilling rig are controlled to achieve the purpose of improving the drilling efficiency. In this way, the drilling efficiency and operating efficiency of the rotary drilling rig under various working conditions can be effectively improved, and the application range is wide and the reliability is high.

[0086] Specifically, in one embodiment, the data acquisition module 101 is also used to acquire drilling-related data of the drilling state of the rotary drilling rig based on the operation data.

[0087] Among them, the feature screening result generation module is used to perform feature importance screening based on drilling-related data and drilling efficiency models to generate feature screening results. The working condition information determination module is used to determine working condition information based on working condition data. The drilling parameter acquisition module is used to obtain the drilling parameters under each working condition in the working condition information one by one based on the features to be optimized and the working condition information.
