Embodiment Construction

[0041] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0042] Such as figure 1 The intelligent identification method of the operating condition of the rod pumping unit includes the following steps:

[0043] Step 1: Collect the above-hole dynamometer diagram and convert it into an underground dynamometer diagram. The specific steps are as follows:

[0044] Step 1.1, in order to ensure the integrity of the input signal data information and fully characterize the working condition characteristics of the automatic control system of the rod pumping unit, that is, the collected input signal fully represents the change trend of the dynamometer curve, and the dynamometer curve The resolution is relatively delicate, the shape of the dynamometer diagram in the four areas is clear, and the information of the original signal is restored by means of discrete sampling points; the sampling frequency of the ana...

Abstract

The invention discloses an intelligent identification method for the operation condition of a sucker rod type oil pumping unit. The intelligent identification method comprises the steps that firstly, on-well indicator diagrams are collected and converted into underground indicator diagrams; qualitative analysis and quantitative calculation are conducted on the underground indicator diagrams, so that the feature values of the indicator diagrams of various working conditions are obtained; finally, the working state of the sucker rod type oil pumping unit is analyzed through the feature values of the indicator diagrams of various working conditions. By the adoption of the intelligent identification method for the operation condition of the sucker rod type oil pumping unit, the operation state of a current system can be accurately and rapidly judged when the operation condition of the sucker rod type oil pumping unit is identified in real time, the actual operation condition is provided, implementation is easy, operation is stable, the purpose that the working condition of the sucker rod type oil pumping unit is automatically identified, and the operation state of the system is adjusted in real time can be achieved easily , the overall efficiency is improved, and manpower and material resources are saved greatly.

Description

technical field [0001] The invention belongs to the technical field of oil field production automation and information management, and in particular relates to an intelligent identification method for operating conditions of a rod pumping unit. Background technique [0002] The existing methods for identifying the operating conditions of rod pumping units are all manually, that is, technicians or experts observe the dynamometer diagram measured by the polished rod dynamometer, and then analyze and interpret the dynamometer diagram to judge the oil well. The working status of the device. The observation is often subjective. Due to the different experience and perception ability of different personnel, there are certain errors in the accuracy of working condition identification, and the identification of the working condition of the rod pumping unit requires a lot of manpower and material resources. Contents of the invention [0003] The purpose of the present invention is ...
