[0023] The accompanying drawings are used to provide a further understanding of the present invention and constitute a part of the specification. Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation of the present invention. In the accompanying drawings:

[0027] In the accompanying drawings, the same reference numerals are used for the same components. In addition, the accompanying drawings are not drawn according to the actual scale. DETAILED DESCRIPTION

[0028] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0029] The prior art (CN104766522A) relates to an accident simulation method for drilling simulation equipment, which includes a simulation device for simulating a land drilling rig, the simulation device includes a drilling rig simulator, a front-end operating console, a teacher operating console, and a three-channel ring screen projection display system, wherein the front-end operating console includes a parameter computer, wherein the parameter computer serves as a distributed host computer to complete data acquisition and control of the entire system, including collecting the position of the drawworks clutch, the position of the turntable clutch, and the position of the pump stroke regulator; simulating the lifting and lowering control of the drawworks, the speed control of the mud pump, and the logic control of the top drive; monitoring the hanging weight, drilling pressure, and torque, the main control computer and the graphic computer complete the execution of the system main program and the processing and display of the ring screen graphics, and the accident and special situation simulations include adhesion drill jam simulation, sand sedimentation drill jam simulation, mud bag drill jam simulation, male cone salvage simulation, and fallen object grinding and milling simulation.

[0030] It can be seen that the prior art (CN104766522A) discloses a drilling rig simulator and mentions that the drilling rig model includes a derrick model and a base model, but there is no direct connection between the drilling rig winch and the digital twin in the prior art (CN104766522A). Therefore, the prior art (CN104766522A) does not disclose the digital twinning of the drilling rig winch used for drilling.

[0031] The prior art (CN104236874B) relates to a method for simulating drill pipe load of a top drive drilling rig: a bottom simulated torque, a resistance simulated torque and a simulated moment of inertia of a simulated drill pipe are given according to the working condition to be simulated; the bottom simulated speed is calculated according to the bottom simulated torque, the resistance simulated torque and the simulated moment of inertia; the speed of the driving device in rotation is measured and used as the top simulated speed; the simulated deformation angle is calculated according to the bottom simulated speed and the top simulated speed; the simulated elastic moment is calculated according to the simulated deformation angle; the top simulated torque is calculated according to the simulated elastic moment bottom simulated torque. The above method can simulate the output of the top torque of the drill pipe in the actual drilling process without installing the drill pipe, and can simulate the output of the top torque of the drill pipe under different working conditions, thereby formulating the output strategy of the top drive drilling rig.

[0032] It can be seen that the prior art (CN104236874B) simulates the drill pipe load of the top drive drilling rig. However, there is no direct connection between the drilling rig winch and the digital twin in the prior art (CN104236874B). Therefore, the prior art (CN104236874B) does not disclose the digital twin of the drilling rig winch used for drilling.

[0033] The prior art (CN104933946B) discloses a drilling rig model of a land drilling rig installation and operation simulation system with independent intellectual property rights. The system is based on computer simulation technology and refers to the actual operation process at the drilling operation site to realistically simulate the drilling process of the ZJ70D land drilling rig. It is used for technical skills training of operators at the drilling site, which enhances the visibility and immersion of teaching and training, shortens the training cycle, improves the training effect, and reduces the training cost.

[0034] It can be seen that the prior art (CN104933946B) proposed a drilling rig model for a land drilling rig installation and operation simulation system, and simulated the derrick and base of the drilling rig. However, there is no direct connection between the drilling rig winch and the digital twin in the prior art (CN104933946B). Therefore, the prior art (CN104933946B) does not disclose the digital twinning of the drilling rig winch used for drilling.

[0035] In view of the above-mentioned defects of the prior art, the present invention constructs a digital twin mapping model through the drilling rig winch entity, and the digital twin is connected to the device entity through the digital twin mapping model; the sensor is installed on the drilling rig winch, connected to the device through the data interface, and the relevant data is collected and the protocol is parsed through the digital twin mapping model. The present invention realizes the virtual-real interaction of the drilling rig winch equipment entity in the digital space, which helps to improve the inherent safety of the winch. The present invention realizes the digital twin of the drilling rig winch, which can diagnose and predict equipment faults, optimize the production process, and monitor the quality status of the product in real time.
