[0055] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0056] In the existing technology, top drive control systems are generally only targeted at certain specific working conditions. Due to the constraints of monitoring hardware conditions, the comprehensiveness of their control and mechanism analysis mapping is low, and they often cannot take into account the control of drill jumping and stick-slip vibration.

[0057] In order to overcome the above technical problems, the present application discloses a drilling top drive abnormality suppression method, device, equipment and storage medium, which can realize comprehensive monitoring and control of drill jumping phenomenon and stick-slip vibration phenomenon in the drilling top drive control system.

[0058] See also Figure 1 As shown, an embodiment of the present invention discloses a method for suppressing abnormalities in a top drive of a well, which is applied to a top drive control system of a well, comprising:

[0059] Step S11: determining the drilling trip condition data corresponding to the downhole drilling tool through the data collected by the local first system sensor, and determining the stick-slip vibration condition data corresponding to the top drill pipe of the drilling through the data collected by the second sensor.

[0060] In this embodiment, it is necessary to collect operating condition data through sensors of the drilling top drive control system. Specifically, it is necessary to collect operating condition data through sensors of the data acquisition module. It is necessary to collect the mechanical penetration rate of the downhole drill tool at multiple time periods through the local first system sensor. Then, the average axial speed, maximum axial speed, and minimum axial speed of the drill tool are determined based on the mechanical penetration rate of the drill tool. Furthermore, it is necessary to collect the maximum drill speed, minimum drill speed, and average drill speed corresponding to the top drill pipe of the drilling through the second system sensor. Then, based on the maximum drill speed, minimum drill speed, average drill speed, system parameters, and drill pipe parameters, the top drive drill string coupling mechanism system calculates the comprehensive maximum drill speed, comprehensive minimum drill speed, and comprehensive average drill speed corresponding to the downhole drill tool. It should be noted that the mechanical penetration rate of the downhole drill tool at multiple time periods is used to calculate the degree of the drilling condition, and the maximum drill speed, minimum drill speed, and average drill speed corresponding to the top drill pipe are used to calculate the stick-slip vibration condition data.

[0061] Step S12: Calculate the drilling top drive's drilling jump condition degree value based on the drill tool axial velocity data in the drilling jump condition data, and determine whether drilling jump abnormality occurs by judging whether the drilling jump condition degree value is within a preset drilling jump condition normal range.

[0062] In this embodiment, the jump drill condition degree value needs to be calculated based on the collected jump drill condition data. First, the drill tool mechanical drilling speed, drill tool axial average speed, drill tool axial maximum speed and drill tool axial minimum speed in the jump drill condition data need to be input into the system database module through the industrial communication protocol, and then passed to the mechanism model by the database module as input parameters. It should be noted that the mechanism model is used to calculate the data, and the mechanism model contains a preset jump drill condition degree calculation formula for calculating the jump drill condition degree value of the drilling top drive, and a preset stick-slip vibration condition degree calculation formula for calculating the stick-slip vibration condition degree value.

[0063] First, the drilling top drive's drilling jump condition degree value needs to be calculated based on the drill tool mechanical penetration rate, drill tool axial average speed, drill tool axial maximum speed, and drill tool axial minimum speed using the preset drilling jump condition degree calculation formula. The preset drilling jump condition degree calculation formula is:

[0064] ;

[0065] Among them, T1 is the degree of drilling jump condition, V max is the maximum axial speed of the drill bit, V min is the minimum axial speed of the drill bit, V ave is the average axial speed of the drill tool, and V0 is the mechanical penetration speed of the drill tool.

[0066] After obtaining the current drilling jump condition level value T1, it is necessary to determine whether the drilling jump condition level value T1 is within a preset normal range for the drilling jump condition. If the drilling jump condition level value T1 is within the preset normal range for the drilling jump condition, no adjustment is required. If the drilling jump condition level value T1 has exceeded the preset normal range for the drilling jump condition, it indicates that the top drive motor input speed needs to be adjusted and the input speed needs to be set. It should be noted that the preset normal range for the drilling jump condition can be set according to actual working conditions.

[0067] Step S13: Calculating a stick-slip vibration condition degree value of the drilling top drive based on the drill pipe speed data and the drill tool speed data in the stick-slip vibration condition data, and determining whether stick-slip vibration abnormality occurs based on whether the stick-slip vibration condition degree value is within a preset stick-slip vibration condition normal range.

[0068] In this embodiment, the stick-slip vibration condition degree value can be calculated based on the mechanism model. Specifically, the maximum drill pipe speed, the minimum drill pipe speed, the average drilling speed of the drill pipe, the comprehensive maximum drill tool speed, the comprehensive minimum drill tool speed, and the comprehensive average drill tool speed can be brought into a preset stick-slip vibration condition degree calculation formula through a database module to calculate the stick-slip vibration condition degree value. The preset stick-slip vibration condition degree calculation formula is:

[0069] ;

[0070] Among them, T2 is the stick-slip vibration condition value, ω r_max is the maximum rotation speed of the drill pipe, ω r_min is the minimum speed of the drill pipe, ω r_ave is the average drilling speed of the drill pipe, ω b_max is the maximum integrated speed of the drilling tool, ω b_min is the minimum integrated speed of the drilling tool, ω b_ave is the comprehensive average rotation speed of the drilling tool.

[0071] After obtaining the current stick-slip vibration condition level value T2, it is necessary to determine whether the stick-slip vibration condition level value T2 is within a preset normal stick-slip vibration condition range. If the stick-slip vibration condition level value T2 is within the preset normal stick-slip vibration condition range, no adjustment is required. If the stick-slip vibration condition level value T2 exceeds the preset normal stick-slip vibration condition range, it indicates that the top drive motor input speed needs to be adjusted and the input speed is set. It should be noted that the preset normal stick-slip vibration condition range can also be set according to actual operating conditions.

[0072] Step S14: If a drill jump anomaly occurs, the top drive motor input speed and the hook load are adjusted; if a stick-slip vibration anomaly occurs, the top drill rod torque is adjusted by a preset PID controller.

[0073] In this embodiment, if a drill jump anomaly occurs, the top drive motor input speed needs to be adjusted. Specifically, the top drive motor input speed of the drilling top drive control system needs to be adjusted according to a preset drilling speed range to adjust the top drive motor input speed to the drilling speed corresponding to the preset drilling speed range. Furthermore, if stick-slip vibration anomalies occur, the top drill rod torque needs to be adjusted using a preset PID (Proportion Integration Differentiation) controller. Specifically, if the stick-slip vibration condition level value is not within the preset normal stick-slip vibration condition range, the preset PID controller calculates the target top drill rod torque value and adjusts the top drill rod torque to the target top drill rod torque value. It should be noted that the first and second top drill rod torque values need to be determined using the preset PID controller; it should be noted that the preset PID controller is a PID controller combined with a sliding film adaptive algorithm.

[0074] The first top drill rod torque value is determined by a first torque value calculation formula, and the first torque value calculation formula is:

[0075] ;

[0076] Among them, u PID is the first top drill pipe torque value, K p is the preset proportional gain, K i is the preset integral gain, K d is the preset differential gain; e(t) is the system error of the drilling top drive control system; it should be noted that the system error is the expected speed ω of the drilling tool in the drilling top drive control system R Calculation of rotational speed ω by coupling mechanism system with top drive drill string b The difference between them, that is, e(t)=ω R -ω b .

[0077] The second top drill rod torque value is determined by a second torque value calculation formula, and the second torque value calculation formula is:

[0078] ;

[0079] Among them, u HM is the torque value of the second top drill pipe, fx is the preset motion state function, d c is the preset parameter, slaw is the preset approach rate function. It should be noted that d c For uncertain parameters, the upper and lower limits are designed based on the Lyapunov stability criterion.

[0080] In this embodiment, after sensors collect data on the downhole drill bit's bouncing condition and the stick-slip vibration condition of the top drill rod, the drilling top drive's bouncing condition severity value can be calculated based on the drill rod axial velocity data in the bouncing condition data. This can then be used to determine if a bouncing condition is abnormal. Furthermore, the drilling top drive's stick-slip vibration severity value can be calculated based on the drill rod velocity data and the drill tool velocity data in the stick-slip vibration condition data. This can then be used to determine if a stick-slip vibration abnormality is present. Ultimately, if a bouncing condition occurs, the top drive motor input speed is adjusted. If a stick-slip vibration abnormality occurs, the top drill rod torque is adjusted using a preset PID controller to suppress the abnormal drilling top drive condition. In this way, the state parameters of the drilling top drive control system can be used to identify and process operating conditions, thereby achieving comprehensive online monitoring and control of bouncing and stick-slip vibration phenomena in the drilling top drive control system.
