In complex geological environments, such as areas with variable stratum structures and large differences in rock hardness, it is necessary to frequently adjust the parameters of the drilling rig, including drilling speed, pressure, etc. In traditional methods, it is difficult for operators to make timely and accurate adjustments, which may lead to problems such as excessive wear of the drill bit, low drilling efficiency, and even stuck drill.

DETAILED DESCRIPTION

[0021] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0022] Example: This embodiment provides a remote operation control method for a drilling rig, comprising the following steps:

[0023] S1. Obtain the current first status information of the drilling rig.

[0024] S2. Based on the remote operation instruction, obtain second status information of completing the remote operation instruction.

[0025] The first state information and the second state information both include position coordinate information, three-dimensional posture angle information, pressure sensing information, temperature sensing information and gas collection information.

[0026] In this embodiment, it should be noted that by acquiring position coordinate information, three-dimensional attitude angle information, pressure sensing information, temperature sensing information and gas collection information, multi-dimensional status information is obtained, so that the working status of the drilling rig can be described more comprehensively. By acquiring the second status information after completing the remote operation instruction, the association between the operation instruction and the actual execution result can be established, and the execution effect of each operation instruction can be dynamically evaluated. As an implementation method, when the remote instruction to lift the drill rod is issued, by comparing the first status information and the second status information, it can be accurately determined whether the drill rod is lifted to the expected position and whether abnormal pressure changes or attitude changes occur during the lifting process. In a complex geological environment, gas collection information can help determine whether there is a harmful gas leak underground, and temperature sensing information can detect in advance whether the equipment is at risk of failure due to overheating, providing more adequate protection for the safe operation of the drilling rig.

[0027] S3. Analyze the movement state of the drilling rig according to the first state information, the second state information and the remote operation instruction.

[0028] Among them, the process of analyzing the motion state of the drilling rig is as follows: Compare the position coordinate information and the three-dimensional attitude angle information under the first state information with the position coordinate information and the three-dimensional attitude angle information under the second state information, respectively, and compare the obtained comparison error value with the corresponding control error threshold to determine a first comparison result; Compare the pressure sensing information, temperature sensing information and gas collection information under the first state information with the pressure sensing information, temperature sensing information and gas collection information under the second state information, respectively, and compare the obtained comparison error value with the corresponding control error threshold to determine a second comparison result; The pressure sensing information, the temperature sensing information and the gas collection information under the second state information are respectively compared with the corresponding safety thresholds to determine a third comparison result.

[0029] In this embodiment, it should be noted that by comparing and analyzing the position coordinate information, three-dimensional attitude angle information, pressure sensor information, temperature sensor information and gas collection information respectively, the movement state changes of the drilling rig are evaluated from multiple angles, and the error value obtained by comparison is compared with the control error threshold and the safety threshold, thereby achieving refined control.

[0030] S4. Based on the movement state of the drilling rig, adjust the remote operation command to control the drilling rig to move to a specified state.

[0031] The process of adjusting the remote operation instructions is as follows: If the comparison error value of the position coordinates in the first comparison result is greater than the corresponding control error threshold, or the comparison error value of the three-dimensional posture angle is greater than the corresponding control error threshold, the remote operation instruction is adjusted to control the drilling rig to move to the specified state set by the remote operation instruction; If one of the pressure sensor information, temperature sensor information and gas collection information under the second state information in the third comparison result exceeds the corresponding safety threshold, the remote operation instruction is suspended, and the pressure sensor information, temperature sensor information and gas collection information in the third comparison result are adjusted to be within the corresponding safety threshold; When the third comparison result is within the safety threshold corresponding to the third comparison result, if any comparison error value in the second comparison result exceeds the corresponding control error threshold, the remote operation instruction is suspended, the comparison error value in the second comparison result is adjusted to be within the corresponding control error threshold, the remote operation instruction is restarted, and the drilling rig is controlled to move to the specified state set by the remote operation instruction.

[0032] In addition, it also includes repeatedly obtaining the status information of the drilling rig and controlling the drilling rig to move forward based on remote operation instructions.

[0033] In this embodiment, it should be noted that the remote operation instructions are adjusted according to different comparison results. The dynamic adjustment mechanism can adapt to different working scenarios and drilling rig states. As an implementation method, when the comparison error value of the position coordinates is too large, the instructions will be adjusted in a targeted manner to move the drilling rig to the correct position. When the temperature exceeds the safety threshold, the instructions are suspended and cooling measures are taken. The flexible instruction adjustment method can effectively improve the working efficiency and safety of the drilling rig. When the third comparison result shows that the safety threshold is exceeded, the remote operation instructions are suspended first to ensure safety. The mechanism of restarting the remote operation instructions after the error value is adjusted in the second comparison result can ensure that after the error problem of non-safety critical parameters is solved, the drilling rig can continue to complete the work task according to the instructions, which improves the continuity of the entire operation process. In addition, the status information of the drilling rig is repeatedly obtained, and the drilling rig is continuously controlled to move forward based on the remote operation instructions, forming a cyclic control process, thereby ensuring that the drilling rig always maintains the expected working state during the entire operation process.
