Abstract

The invention relates to a method for monitoring the efficiency of a rod oil pumping system in real time and belongs to the technical field of computer oil field digitalization construction. The method comprises the steps of data collection and the step of data analysis. The step of data collection comprises the following steps that an oil pumping machine indicator diagram method oil well automatic metering and monitoring system is established, the operation states of oil wells in a supervision section are monitored in real time in all weather without interruption, indicator diagram data are collected every ten minutes, and the liquid production capacity is calculated; an electrical parameter data collecting system is established, the parameters such as three-phase current, voltage, active power, reactive power and power factors are collected in real time, and the mass data collected in real time are stored in a special database. The step of data analysis comprises the following steps that system real-time efficiency monitoring software is developed, dynamic parameters reflecting the operation states of the system are obtained by calculating and analyzing the real-time collected data in the special database, and a tendency chart of changes of all technical indexes along time is drawn by comparing stage state operation changing tendencies and is used for guiding production.

Description

technical field [0001] The invention relates to a method for real-time monitoring of the efficiency of a rod pumping system, and belongs to the technical field of digital construction of computerized oil fields. Background technique [0002] All oilfields use portable testers to test the power diagram and input electrical parameters of the pumping system regularly or irregularly, and then use the efficiency calculation, simulation and optimization design software of the pumping system to analyze and calculate the test data. With the development of digital construction in oilfields, an oilfield in the west has established a metering device and a real-time electrical parameter acquisition device for oil wells using the gong diagram method, which can measure gong diagram data and electrical parameters around the clock. At present, there is no method to use the measured real-time data to monitor the oil pumping system. Efficiency calculation, so as to realize real-time monitorin...
