Efficiency tester for rod-pumped well system

Abstract

The utility model discloses an efficiency tester for a rod-pumped well system. A host CPU and a wireless indicator diagram sensor are communicated through a host wireless communication module. The host USB socket is connected with the host CPU through the USB conversion module. The current transformer is connected with a filter circuit in the electrical parameter measurement module. The test clampis connected with a filter circuit in the electrical parameter measurement module through an electrical parameter internal overcurrent and overvoltage protection and step-down transformer, and then is connected with the electrical parameter CPU through an electric energy metering chip and a signal isolation circuit. The electric parameter USB socket is connected with the host USB socket and the electric parameter CPU. The electric parameter USB socket is also connected with the electric energy metering chip through an isolation power supply. The host is further connected with a pressure sensor and a wellhead connector. The host USB socket can also be connected with a computer and an external USB flash disk. The efficiency tester is a multifunctional comprehensive testing instrument for testing multiple electrical parameters, indicator diagrams, working fluid levels and the like of the oil field rod-pumped well, the system efficiency of the rod-pumped well can be calculated, and accurate data are provided for working condition diagnosis and balance analysis of the rod-pumped well.

AI Technical Summary

Problems solved by technology

At present, the dynamometer is used to test the dynamometer diagram, dynamic fluid level and electrical parameters in the oil field, and then the power meter is used to test the electrical parameters. A system efficiency tester with parameters integrated, but it cannot perform synchronous testing of dynamometer diagrams and electrical parameters

Such test data will inevitably bring misjudgment to system efficiency diagnosis and analysis

In addition, when testing electrical parameters, the voltage of the front-end three-phase motor test voltage line and the test terminal line can reach 1140V high voltage. At present, the voltage test line of the system efficiency tester in the market directly enters the operation host through the interface. If the test line is worn or exposed or the interface If the operator is not careful, it will cause casualties, which is a great safety hazard.

What's more, the communication between the system efficiency tester and the upper computer in the current market needs to install the driver. Disadvantages of heavy and inconvenient to carry and operate
