Oil pumping unit indicator diagram diagnosis system and diagnosis method

Abstract

The invention provides an oil pumping unit indicator diagram diagnosis system and a diagnosis method. The diagnosis system comprises: a load sensor for collecting indicator diagram data; an indicator diagram data collecting module for acquiring indicator diagram data from the load sensor and pre-processing the indicator diagram data, and transmitting pre-processed indicator diagram data to a mobile terminal; a mobile terminal for formatting the pre-processed indicator diagram data; a cloud terminal indicator conversion service module for converting the formatted indicator diagram data into a pump indicator diagram data and transmitting the pump indicator diagram data to the mobile terminal; and a nerve network module for receiving the pump indicator diagram data from the mobile terminal, performing diagnosis on the pump indicator diagram data, obtaining a diagnosis result, transmitting the diagnosis result to the mobile terminal for display. The diagnosis system and the diagnosis method of the invention address the problem of low efficiency of prior art technology in performing diagnosis on oil-pumped well failure, and achieve the purpose of performing diagnosis on the oil-pumped well failure in a simple and efficient manner.

Description

technical field [0001] The invention relates to the technical field of geological exploration, in particular to a diagnostic system and a diagnostic method for an indicator diagram of a pumping unit. Background technique [0002] The fault diagnosis of pumping wells mainly depends on the dynamometer diagram, which is the relationship curve between the suspension point load and the suspension point displacement. The tool for measuring the dynamometer diagram is called: power meter, which is specially used to test oil well pumps In the case of working in the well, the maximum and minimum loads of the oil well pump during the lifting process, as well as the changes in loading and unloading can be measured through the dynamometer diagram, and the fracture of the sucker rod can be judged more accurately by the dynamometer diagram. Detachment, tubing leakage, fixed valve blockage or leakage, and can determine the faults of oil wells such as wax deposition, sand production, pump de...

AI Technical Summary

Problems solved by technology

[0003] However, the current analysis of the dynamometer diagram mainly relies on manual or automatic judgment using simple geometric analysis methods. Manual analysis requires on-site staff to have rich diagnostic experience, and the efficiency is low, while geometric analysis methods cannot analyze complex functions. Figure shape for accurate judgment

[0004] For the above problems, no effective solution has been proposed
