[0002] With the continuous growth of global energy demand, the development and utilization of marine energy have gradually become the focus of attention of various countries. As an important field for developing and utilizing marine resources, the technological progress and innovation in ocean engineering are of great significance for promoting the development of the marine economy. As a key equipment in ocean engineering, the expansion and innovation of rig technology play an important role in improving the exploitation efficiency and safety of marine resources.

[0003] In ocean engineering, a rig needs to face more complex environments and conditions, such as the corrosion of seawater, the impact of ocean currents, and the complex geology of the seabed. Therefore, stricter requirements are imposed on the performance and technology of the rig. The rig needs to have higher stability and reliability to cope with the uncertainty and complexity of the marine environment. During the drilling process, problems such as wear and fracture of the drill bit will affect the drilling speed and the stability of the rig operation.

The setting of the initial state monitoring duration can be used to optimize data collection and provide a basis for subsequent state judgment. The drill bit state judgment unit judges whether there is an abnormality in the drill bit state according to the operation data obtained by the drill bit state monitoring unit. Early detection of abnormal drill bit operation improves the reliability and safety of the drill, and reduces possible damage and downtime. When the drill bit state warning unit determines that there is an abnormality in the drill bit state, it determines the abnormal risk warning level according to the operation data and issues a corresponding warning, improving the intelligence of the system, enabling the operation and maintenance personnel to make a quicker response, and reducing the risk of losses. The drill start-stop control unit determines whether to stop the operation of the drill according to the abnormal risk warning level. In case of serious abnormal situations, it stops the operation of the drill in time to prevent possible equipment damage or accidents and improve work safety. The monitoring duration adjustment unit adjusts the initial state monitoring duration according to the operation data when the drill bit state judgment unit determines that the drill bit state is normal to obtain the final state monitoring duration, realizing the dynamic adjustment of the monitoring duration, optimizing the monitoring strategy according to the actual operation situation, and improving the flexibility and efficiency of the system. Through the collaborative work of multiple units, it can play a role in real-time monitoring, abnormal judgment, and intelligent control, improve the work efficiency, safety, and reliability of the drill, reduce the possible risk of losses, and provide an advanced monitoring and control solution for related industries.

The drawings are only for the purpose of illustrating the preferred embodiments and are not considered to be a limitation of the present invention. In the drawings:

[0063] Figure 1 It is a functional block diagram of an adaptive monitoring and control system for a drilling rig provided by an embodiment of the present invention. Specific Embodiments

[0064] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art. It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0065] In the process of deep - sea oil and gas resource development in our country, the role of the drilling rig is crucial. Due to the particularity of the marine environment, the drilling rig needs to face many challenges during actual operation, such as seawater corrosion, ocean current impact, and complex seabed geology. These factors make the requirements for the performance and technology of the marine drilling rig more stringent, and put forward higher requirements for the stability and reliability of the drilling rig.

[0066] In order to cope with the uncertainty and complexity of the marine environment, it is necessary to fully consider the particularity of the marine environment to ensure high stability and reliability. At the same time, by continuously increasing the drilling speed and efficiency, reducing the risk of wear and fracture, and realizing real - time monitoring and intelligent control, the smooth completion of the drilling task can be ensured.

[0067] Refer to Figure 1 As shown, this embodiment provides an adaptive monitoring and control system for a drilling rig, including:

[0068] A monitoring and judgment unit, configured to obtain the start - stop state of the drilling rig and determine whether to monitor the bit state according to the start - stop state;

[0069] A bit state monitoring unit, configured to preset an initial state monitoring duration when the monitoring and judgment unit determines to monitor the bit state, and obtain bit operation data within the initial state monitoring duration;

[0070] A bit state judgment unit, configured to determine whether there is an abnormality in the bit state according to the bit operation data obtained by the bit state monitoring unit;

[0071] The drill bit status warning unit is used to determine the abnormal risk warning level of the drill bit according to the drill bit operation data when the drill bit status judgment unit determines that the drill bit status is abnormal, and issue a warning according to the abnormal risk warning level;

[0072] The drill rig start-stop control unit is used to determine whether to stop the operation of the drill rig according to the abnormal risk warning level;

[0073] The monitoring duration adjustment unit is used to adjust the initial status monitoring duration according to the drill bit operation data to obtain the final status monitoring duration when the drill bit status judgment unit determines that the drill bit status is normal.

[0074] It can be understood that in this embodiment, by monitoring the status of the drill rig, the system can determine whether drill bit status monitoring is required, which helps to avoid unnecessary monitoring and save resources and time. When the monitoring judgment unit determines that drill bit status monitoring is required, the drill bit status monitoring unit sets an initial monitoring duration and collects the operation data of the drill bit within the set duration, ensuring real-time and accurate monitoring of the drill bit status. The drill bit status judgment unit determines whether the drill bit status is abnormal based on the data collected by the drill bit status monitoring unit, which helps to promptly discover potential problems and prevent further damage or accidents. The drill bit status warning unit determines the warning level and issues a corresponding warning, enabling the operator to respond quickly and take necessary measures. The drill rig start-stop control unit decides whether to stop the operation of the drill rig according to the warning level, which helps to prevent further equipment damage or accidents and protect personnel safety. The monitoring duration adjustment unit adjusts the initial monitoring duration according to the operation data of the drill bit to obtain a more accurate monitoring result, enabling the system to adapt to different working conditions and requirements. This embodiment improves efficiency and accuracy by performing real-time and accurate drill bit status monitoring, promptly discovering and warning of potential problems, and adjusting the monitoring duration according to the actual situation.

[0075] In some embodiments of the present application, when the monitoring judgment unit is used to obtain the start-stop status of the drill rig and determine whether to perform drill bit status monitoring according to the start-stop status, it includes:

[0076] The start-stop status includes: start operation status and stop operation status;

[0077] When the start-stop status of the drill rig is the start operation status, the monitoring judgment unit determines to perform drill bit status monitoring;

[0078] When the start-stop status of the drill rig is the stop operation status, the monitoring judgment unit determines not to perform drill bit status monitoring.

[0079] It can be understood that in this embodiment, by judging whether it is necessary to monitor the state of the drill bit according to the start-stop state of the drill rig, the monitoring time can be reasonably arranged according to the actual situation, avoiding monitoring at unnecessary times, and improving the monitoring efficiency and the service life of the drill bit.

[0080] In some embodiments of the present application, the drill bit operation data includes: the real-time vibration frequency of the drill bit, the real-time vibration amplitude of the drill bit, and the real-time temperature of the drill bit surface.

[0081] In some embodiments of the present application, when the start-stop state of the drill rig is the start-up operation state and the monitoring and judging unit determines to perform drill bit state monitoring, it includes:

[0082] The monitoring and judging unit obtains the real-time vibration frequency of the drill bit, denoted as A;

[0083] The monitoring and judging unit preset a first preset drill bit vibration frequency value A1 and a second preset drill bit vibration frequency value A2, and A1 > A2;

[0084] The monitoring and judging unit determines the drill bit vibration frequency state score value Aa according to the real-time vibration frequency A of the drill bit, the first preset drill bit vibration frequency value A1, and the second preset drill bit vibration frequency value A2;

[0085] When A2 < A ≤ A1, the monitoring and judging unit determines that the drill bit vibration frequency state score value Aa is 100;

[0086] When A ≤ A2 or A > A1, the calculation formula for the drill bit vibration frequency state score value Aa determined by the monitoring and judging unit is as follows:

[0087]

[0088] Where K is a constant coefficient.

[0089] In this embodiment, by setting the first preset drill bit vibration frequency value A1 and the second preset drill bit vibration frequency value A2, and determining the drill bit vibration frequency state score value Aa according to the comparison between the real-time vibration frequency A and these two preset values, the drill bit vibration frequency state score value Aa is calculated based on the deviation percentage of the real-time vibration frequency A of the drill bit relative to the preset threshold values, the first preset drill bit vibration frequency value A1 and the second preset drill bit vibration frequency value A2. The relationship between the score and the frequency deviation is balanced by the constant coefficient K, with a full score of 100. The greater the deviation, the lower the score. In this way, the state of the drill bit can be evaluated more accurately, potential problems can be discovered and processed in time, and the normal operation and safety of the drill rig can be ensured.

[0090] In some embodiments of the present application, when the start-stop state of the drill is the start-running state and the monitoring and judgment unit determines to monitor the bit state, it further includes:

[0091] The monitoring and judgment unit obtains the real-time vibration amplitude of the bit, denoted as B;

[0092] The monitoring and judgment unit preset a first preset bit vibration amplitude value B1 and a second preset bit vibration amplitude value B2 in advance, and B1 > B2;

[0093] The monitoring and judgment unit determines the bit vibration amplitude score value Ba according to the real-time vibration amplitude B of the bit, the first preset bit vibration amplitude value B1, and the second preset bit vibration amplitude value B2;

[0094] When B2 < B ≤ B1, the monitoring and judgment unit determines that the bit vibration amplitude state score value Ba is 100;

[0095] When B ≤ B2 or B > B1, the calculation formula for the bit vibration amplitude state score value Ba determined by the monitoring and judgment unit is as follows:

[0096]

[0097] where F is a constant coefficient.

[0098] In this embodiment, by presetting the first preset bit vibration amplitude value B1 and the second preset bit vibration amplitude value B2, different vibration amplitude thresholds can be flexibly set according to different drilling requirements and drill models, improving the adaptability and versatility of the monitoring system. By calculating the bit vibration amplitude score value Ba, the vibration amplitude state of the bit can be quantitatively evaluated, providing a scientific basis for the maintenance and replacement of the bit, reducing the maintenance cost and operation difficulty.

[0099] Among them, the bit vibration amplitude score value Ba is calculated based on the deviation percentage of the real-time vibration frequency A of the bit relative to the preset threshold values, the first preset bit vibration amplitude value B1 and the second preset bit vibration amplitude value B2. The relationship between the score and the frequency deviation is balanced by the constant coefficient F, with a full score of 100. The greater the deviation, the lower the score. In this way, the state of the bit can be evaluated more accurately, potential problems can be detected in time and processed, ensuring the normal operation and safety of the drill.

[0100] In some embodiments of the present application, when the start-stop state of the drill is the start-running state and the monitoring and judgment unit determines to monitor the bit state, it further includes:

[0101] The monitoring and judgment unit obtains the real-time temperature on the surface of the bit, denoted as C;

[0102] The monitoring and judging unit preset a first preset bit surface temperature value C1 and a second preset bit surface temperature value C2 in advance, and C1 > C2;

[0103] The monitoring and judging unit determines a bit surface temperature state score value Ca according to the real-time bit surface temperature C, the first preset bit surface temperature value C1, and the second preset bit surface temperature value C2;

[0104] When C2 < C ≤ C1, the monitoring and judging unit determines that the bit surface temperature state score value Ca is 100;

[0105] When C ≤ C2 or C > C1, the calculation formula for the bit surface temperature state score value Ca determined by the monitoring and judging unit is as follows:

[0106]

[0107] where H is a constant coefficient.

[0108] In this embodiment, by setting the first preset bit surface temperature value C1 and the second preset bit surface temperature value C2, the limitation on the bit surface temperature can be flexibly adjusted according to actual needs, improving the accuracy and adaptability of temperature monitoring. Determining the bit surface temperature state score value Ca according to the real-time bit surface temperature C, the first preset bit surface temperature value C1, and the second preset bit surface temperature value C2 can more accurately reflect the actual working state of the bit, providing a reliable basis for further fault diagnosis or optimization control.

[0109] Among them, the bit surface temperature state score value Ca is calculated based on the deviation percentage of the real-time bit vibration frequency A relative to the preset threshold values, i.e., the first preset bit surface temperature value C1 and the second preset bit surface temperature value C2. The constant coefficient H is used to balance the relationship between the score and the frequency deviation. With a full score of 100, the greater the deviation, the lower the score. This can more accurately evaluate the state of the bit, so as to timely discover potential problems and handle them, ensuring the normal operation and safety of the drilling rig.

[0110] Specifically, K, F, and H are constants that balance the relationship between the score and the frequency deviation, and can be set according to specific circumstances. This embodiment does not make specific limitations.

[0111] It can be understood that in this embodiment, when the start-stop state of the drilling rig is the start-up operation state, the monitoring and judgment unit determines to monitor the bit state, obtains the real-time vibration frequency, real-time vibration amplitude and surface real-time temperature of the bit, and calculates the vibration frequency state score value, vibration amplitude score value and surface temperature state score value of the bit according to the preset vibration frequency value, vibration amplitude value and surface temperature value. The state of the bit is monitored in real time, abnormal situations are detected in time, and bit damage and the impact on drilling efficiency are avoided. At the same time, multi-dimensional indicators are used for monitoring, which can more comprehensively reflect the state of the bit and improve the accuracy and reliability of monitoring. The system has a simple structure and is easy to operate, and can be widely applied to various types of drilling rigs.

[0112] In some embodiments of the present application, after the monitoring and judgment unit obtains the surface temperature state score value Ca of the bit, the vibration amplitude state score value Ba of the bit and the vibration frequency state score value Aa of the bit, it includes:

[0113] The monitoring and judgment unit performs summation operation according to the surface temperature state score value Ca of the bit, the vibration amplitude state score value Ba of the bit and the vibration frequency state score value Aa of the bit, and obtains the comprehensive state score value D of the bit, D = Aa + Ba + Ca;

[0114] The bit state judgment unit preset a first preset bit state score value D1, a second preset bit state score value D2, a third preset bit state score value D3 and a fourth preset bit state score value D4 in advance, and D1 > D2 > D3 > D4;

[0115] When D ≤ D4, the bit state judgment unit determines that the bit state is normal;

[0116] When D > D4, the bit state judgment unit determines that the bit state is abnormal.

[0117] It can be understood that the monitoring and judgment unit and the bit state judgment unit in this embodiment can comprehensively judge the state of the bit according to the surface temperature state score value Ca of the bit, the vibration amplitude state score value Ba of the bit and the vibration frequency state score value Aa of the bit, detect the abnormalities existing in the bit in time, and improve the service life and safety of the bit.

[0118] In some embodiments of the present application, after the bit state judgment unit determines that the bit state is abnormal, it includes:

[0119] The bit state warning unit preset a first preset warning level E1, a second preset warning level E2, a third preset warning level E3, a fourth preset warning level E4 in advance, and E1 > E2 > E3 > E4;

[0120] When D > D1, the drill bit status warning unit determines that the fourth preset warning level E4 is the abnormal risk warning level of the drill bit;

[0121] When D1 ≥ D > D2, the drill bit status warning unit determines that the third preset warning level E3 is the abnormal risk warning level of the drill bit;

[0122] When D2 ≥ D > D3, the drill bit status warning unit determines that the second preset warning level E2 is the abnormal risk warning level of the drill bit;

[0123] When D3 ≥ D > D4, the drill bit status warning unit determines that the first preset warning level E1 is the abnormal risk warning level of the drill bit.

[0124] It can be understood that in this embodiment, after the drill bit status judgment unit determines that the drill bit status is abnormal, the drill bit status warning unit sets different warning levels and determines the abnormal risk warning level according to different D values. Hierarchical warning can better help users understand the severity of the risk, so as to make corresponding treatment decisions and prevent potential drilling accidents or equipment damage.

[0125] In practical applications, according to the different states and parameter changes of the drill bit, the warning unit can flexibly adjust the warning level and issue corresponding risk warnings in a timely manner, thereby effectively reducing the risk during the drilling process. The introduction of the warning mechanism can not only improve the safety of drilling operations, but also extend the service life of the drill bit to a certain extent and reduce the maintenance cost.

[0126] In some embodiments of the present application, after the drill bit status warning unit determines that the i-th preset warning level Ei is the abnormal risk warning level of the drill bit, i = 1, 2, 3, 4, it further includes:

[0127] The drilling rig start-stop control unit obtains the abnormal risk warning level Ei of the drill bit;

[0128] When Ei ≥ E3, the drilling rig start-stop control unit determines to stop the operation of the drilling rig;

[0129] When Ei < E3, the drilling rig start-stop control unit determines that the drilling rig continues to operate.

[0130] It can be understood that in this embodiment, when the abnormal risk warning level of the drill bit is the i-th preset warning level Ei, the drill bit status warning unit will determine this level. Among them, the value range of i is 1, 2, 3, 4. The rig start-stop control unit will obtain the abnormal risk warning level Ei of the drill bit. If Ei is greater than or equal to E3, the rig start-stop control unit will decide to stop the operation of the rig to prevent possible further damage or accidents. If Ei is less than E3, the rig start-stop control unit will decide to keep the rig running continuously because the risk at this time is relatively low and will not pose too much threat to the rig or the staff. This helps to ensure the safe operation of the rig and avoid various problems that may be caused by the abnormality of the drill bit. At the same time, taking different countermeasures according to different warning levels can also improve work efficiency and response speed.

[0131] In some embodiments of the present application, when D ≤ D4 and the drill bit status determination unit determines that the drill bit status is normal, it includes:

[0132] The monitoring duration adjustment unit obtains the initial status monitoring duration, denoted as G;

[0133] The monitoring duration adjustment unit preset a monitoring duration adjustment coefficient g, and 1.5 > g > 1;

[0134] The monitoring duration adjustment unit adjusts the initial status monitoring duration G according to the monitoring duration adjustment coefficient g to obtain the final status monitoring duration, denoted as Ga, and Ga = G * g.

[0135] It can be understood that in this embodiment, when the specific condition D ≤ D4 is met, the drill bit status determination unit determines that the drill bit status is normal and further adjusts the monitoring duration. First, the initial status monitoring duration G is obtained to preliminarily judge the status of the drill bit. A monitoring duration adjustment coefficient g is set, and g is used to adjust the initial monitoring duration to make the monitoring more accurate or adapt to different working conditions. Usually, the value of g will be between 1.5 and 1, which means that the monitoring duration may be shorter than the initial status monitoring duration, but not much shorter. Finally, according to the set monitoring duration adjustment coefficient g, the final monitoring duration Ga is calculated. The mechanism of judging the drill bit status under specific conditions and correspondingly adjusting the monitoring duration helps to more accurately monitor the real-time status of the drill bit and improve the use efficiency and safety of the equipment.

[0136] It can be understood that in this embodiment, by introducing the monitoring duration adjustment coefficient g, the monitoring duration can be flexibly adjusted according to different working conditions and requirements, enabling better adaptation to different working environments and requirements and improving its adaptability. By adjusting the monitoring duration, unnecessary monitoring time can be reduced while ensuring the monitoring effect, thereby improving work efficiency. Reducing unnecessary monitoring time can reduce energy consumption and equipment wear, thus extending the service life of the equipment and saving maintenance costs. By adjusting the monitoring duration, more accurate monitoring can be carried out at critical moments, thereby improving the accuracy of the monitoring results.
