In modern drilling operations, the performance of drilling equipment directly affects drilling efficiency and operation safety. During the drilling process, the operating status of key components such as the drill bit, rotary head, and drill pipe, as well as the stress conditions of the connection parts and drilling tower, and the geological characteristics of the rock formations, all have a significant impact on drilling efficiency, drilling safety, and drilling costs.

[0003] In traditional technologies, each link in the drilling operation (such as drill bit efficiency, rotary head torque, drill pipe bending, etc.) often adopts a single or intermittent data collection method, which cannot comprehensively reflect the operating status of each component in real time. This limits the comprehensive performance analysis of the drilling device and also affects the timely discovery of abnormal conditions or potential faults during the operation.

[0015] The present invention provides a drilling device operation performance test system based on data acquisition.

This separate monitoring strategy can detect the status of the drill bit, rotary head and drill pipe in real time.

Compared with the traditional single stress indicator, this multi-dimensional stress monitoring method can provide more detailed stress change data, which helps to accurately determine whether there is stress concentration or unevenness at the connection. This can more accurately predict the potential failure risk of the connection.

[0017] (3) During drilling operations, the stress state of the connection between the drill bit, rotary head and drill pipe, as well as the drilling tower, directly affects the safety and service life of the equipment. The present invention effectively compensates for the problem of insufficient monitoring of these parts in traditional technologies by using the stress distribution acquisition module to monitor stress at key connection points and the base and top of the drilling tower. Real-time collection and analysis of stress changes can provide early warning of potential equipment failures and avoid equipment failures or safety accidents caused by excessive stress.

[0018] (4) By dynamically optimizing key parameters such as drill bit rotation speed, drilling fluid flow rate, and drilling speed, the present invention can effectively reduce excessive wear of drilling equipment and reduce the need for frequent replacement or maintenance of equipment, thereby extending the service life of the equipment. In addition, the system avoids premature damage to the equipment and reduces long-term maintenance costs by specifically adjusting the operating status of each device. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 1 The present invention is a flowchart of a drilling device operation performance testing system based on data acquisition. DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in 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.

[0021] Example 1 The drill bit is the component that comes into direct contact with the formation during drilling, and its operating status directly affects drilling efficiency. The wear degree, axial load and rotation speed of the drill bit will affect the service life and working effect of the drill bit. If the drill bit is excessively worn or used improperly, it may lead to a decrease in drilling speed, an increase in production costs, and even failures such as drill breakage or drill jamming, resulting in interruption of operations.

[0022] See also Figure 1 The present invention provides a drilling device operation performance test system based on data acquisition, comprising: The data acquisition module is used to determine the geological conditions and key construction areas in the construction drilling area and its surroundings, and arrange exploration points and data acquisition points according to the drilling depth, rock layer distribution and construction requirements, and collect the operating parameters of the drill bit, rotary head and drill pipe of the drilling device in real time during the drilling operation to form a multi-dimensional operation data group; The stress distribution acquisition module is used to install stress sensors at the connection between the drill bit, rotary head and drill rod to collect stress data of the connection points in real time and form a stress distribution data set of the connection points; and to install stress sensors at the base and top of the drilling tower to collect stress data of the drilling tower base. and the stress on the top of the derrick , forming a tower body bearing data group; The drilling environment collection module is used to collect the volume of broken rock per unit time in real time during the drilling operation. , rock type coefficient , rock density , drilling depth H and formation temperature , forming an environmental parameter group; The performance prediction and analysis module is used to establish a drilling device operation performance correlation analysis model based on the collected multi-dimensional operation data group, connection point stress distribution data group, tower body load data group and environmental parameter group using machine learning algorithms. After training the drilling device operation performance correlation analysis model, the following calculations are performed to obtain the drill bit efficiency coefficient: , Rotating head torque stability coefficient , drill pipe bending resistance coefficient , stress distribution coefficient of the connection part and the drilling tower stress variation coefficient ; Evaluation module for drilling efficiency factor , Rotating head torque stability coefficient , drill pipe bending resistance coefficient , stress distribution coefficient of the connection part and the drilling tower stress variation coefficient Evaluate them separately to obtain corresponding test results, and generate corresponding strategies based on the corresponding test results.

[0023] In this embodiment, by monitoring the wear rate, temperature rise change and other parameters of the drill bit, an early warning can be issued before the drill bit fails, avoiding downtime and equipment loss caused by drill bit damage. The rotating head is responsible for providing rotational motion, which directly affects the rotation speed and footage of the drill bit. The instantaneous torque value and average torque value of the rotating head reflect its working state. If the torque of the rotating head is unstable, it may cause discontinuity in drilling operations and even equipment damage. The drill pipe is subjected to large axial loads and bending forces during drilling, and it will vibrate when working. The bending radius, vibration amplitude and maximum stress of the drill pipe are key indicators for judging whether the drill pipe is in normal working condition. If the drill pipe is excessively bent or vibrated, it may cause breakage or stuck drill, and in severe cases, it may even cause the entire drilling operation to stagnate. By real-time monitoring of the stress and vibration of the drill pipe, possible fatigue damage of the drill pipe can be discovered in advance, and the operation mode or parts can be adjusted in time to avoid drilling accidents caused by damage to the drill pipe.

[0024] During drilling operations, the stress state of the connection between the drill bit, rotary head and drill pipe, and the derrick directly affects the safety and service life of the equipment. The present invention effectively compensates for the problem of insufficient monitoring of these parts in traditional technologies by using the stress distribution acquisition module at key connection points and the derrick base and top.
