Example Embodiment
[0024] Example 1: Single well control method
[0025] The electrical parameter tester tests the voltage and current data of the main motor during operation, and the work diagram tester tests the suspended point load and displacement data; the data is transmitted to the data acquisition module inside the oil well controller through wired or wireless transmission, and the module is transmitted wirelessly Method, the data is transmitted to the upper computer system, and the upper computer system diagnoses and optimizes the oil well working conditions as follows through the test data analysis:
[0026] Stroke frequency optimization: When it is found that the oil well is insufficiently supplied with fluid, reduce the stroke frequency so that the volumetric efficiency of the pump is above the set lower limit. If the stroke frequency exceeds the allowable lower limit, the intermittent oil recovery prompt diagnosis result will be output, and the current Intermittent pumping system under wo...

[0030] Example 2: Multi-well control mode ( Figure 4 )
[0031] A host computer system can control energy-saving production of multiple oil wells at the same time. Its structure is as Figure 4 Shown. The host computer system is connected to multiple sets of oil well controllers at the same time, and each oil well controller controls the data collection, balance motor and main motor control of one oil well; the host computer system processes the data collection of each oil well controller in sequence according to the set sequence , Diagnose and optimize working conditions, and transmit the optimized results to the corresponding oil well controller at one time.
[0032] The multi-well control method can realize the centralized management of multiple oil wells in a block, save manpower and material resources, save resources, and reduce production costs.
[0033] The oil well energy-saving production control system of the present invention is mainly applied to the production field o...
