[0027] As shown in Figs. 1-2 The present application provides a simulation operation and maintenance detection device for oil production digital equipment based on Internet of Things, comprising: a simulation well operation device, a digital equipment detection device, and a plurality of Zigbee wireless pressure transmitters 9. The simulation well operation device comprises: a simulation pumping unit 1, an operation control cabinet 2, a pumping unit motor 3, a produced injection medium circulating tank 4, a compressed air pump 6, a simulation water injection well 10, and a simulation well base 11. The operation control cabinet 2 is arranged on one side of the simulation well base 11, and its main function is to control and monitor the running state of the entire simulation system. The operation control cabinet 2 is equipped with a PLC inside, which adjusts and controls various operating parameters of the simulation pumping unit 1, such as stroke and stroke frequency, through a pre-set program, to simulate the working condition of the pumping unit in the actual oil field. The pumping unit motor 3 is arranged on the upper end of the simulation well base 11, as well as the simulation pumping unit 1 and the simulation water injection well 10. The simulation well base 11 is also provided with a wellhead oil pressure pipeline 23 and a simulation wellhead. The Zigbee wireless pressure transmitter 9 is arranged on the wellhead oil pressure pipeline 23. The pumping unit motor 3 serves as a power source and drives the simulation pumping unit 1 to move reciprocally through a mechanical transmission device, simulating the actual pumping process. The simulation pumping unit 1 is composed of a simulation pumping unit support, a simulation pumping unit horse head, a simulation pumping unit polished rod, and a rope hanger. The simulation pumping unit polished rod is inserted into the simulation wellhead. The simulation pumping unit polished rod moves up and down with the simulation pumping unit horse head to simulate the pumping action.

The Zigbee wireless working condition sensor 5 is connected to the rope hanger, and the Zigbee wireless working condition sensor 5 is used to monitor the working condition of the pumping unit in real time. The simulation pumping unit 1 is connected to the simulation wellhead through the wellhead oil pressure pipeline 23. The medium flowing in the wellhead oil pressure pipeline 23 represents crude oil or water in the actual oil field. In order to realize the recycling of the medium, the simulation well base 11 is provided with the produced injection medium circulating tank 4 at the lower end, which is connected to the simulation pumping unit 1 through a pipeline.

The Rs485 flow controller 8 is connected to the simulated injection well 10 through a pipeline, and its main function is to adjust the water injection amount of the injection well according to the set flow value. The controller uses the RS485 communication protocol. The Zigbee wireless pressure transmitter 9 is installed on the pipeline of the simulated injection well 10 and is used to monitor the pressure change of the simulated injection well 10 in real time. The Zigbee wireless pressure transmitter 9 transmits pressure data through Zigbee wireless communication technology, so that the operator can monitor the pressure condition of the simulated injection well 10 in real time, ensuring the safe and stable operation of the system.

The voice alarm module 22 gives a voice prompt when the device fails, reminding the operator to take timely measures to avoid accidents. In order to realize comprehensive detection of digital equipment, the unit module to be detected needs to be installed in the corresponding fault module detection port and connected to the operation control cabinet 2 through the standardized fault module detection port. The operation control cabinet 2 sends simulation data signals to the unit to be detected. If an abnormality is found, a warning signal is sent. The operation control cabinet 2 simulates the running state of the digital equipment according to the received data and processes and analyzes the operation condition data of the oil and water wells.

The Zigbee wireless oil pressure gauge monitors the change of oil pressure in real time and transmits the data to the first fault module detection port 12 of the digital equipment detection device; In terms of the simulated injection well 10, the Rs485 vortex flowmeter 7 detects the vortex frequency generated when the fluid flows in the pipeline to calculate the flow, and transmits the data to the operation control cabinet 2 through the RS485 communication protocol. The Rs485 flow controller 8 adjusts the water injection amount of the injection well according to the set flow value, and the Zigbee wireless pressure transmitter 9 monitors the pressure change of the simulated injection well 10 in real time and transmits the pressure data to the second fault module detection port 15 of the digital equipment detection device through Zigbee wireless communication technology.

[0033] The operator can perform fault diagnosis and elimination on the simulated pumping unit 1 through the first fault module detection port 12, the first power switch 13 and the first remote start-stop relay 14 to ensure the normal operation of the simulated pumping unit 1. Similarly, in the water well equipment detection area, the second fault module detection port 15, the second power switch 16 and the second remote start-stop relay 17 are used to detect and control the running state of the simulated injection well 10; During the whole process, the detection switch 18 is used to start or stop the detection process, and the emergency stop button 19 is used to quickly stop the system operation in an emergency. The three-phase current sensor 20 monitors the three-phase current in the system in real time to ensure the stability of the current.
