Method and system for obtaining online real-time data of pumping well fluid level

Abstract

The invention discloses a method and system for obtaining online real-time data of the dynamic liquid level of a pumping unit. The method includes: obtaining the data of the dynamometer diagram and analyzing and processing the data of the dynamometer diagram; calling the dynamic fluid level according to the data of the dynamometer diagram The calculation module calculates the dynamic fluid level data; the method and system provided by the application can calculate the dynamic fluid level data of the pumping well by monitoring the real-time data of the dynamometer diagram, and obtain the real-time data of the dynamic fluid level. The acquisition of real-time data on the dynamic liquid level provides timely data support for improving the lifting efficiency of the oil well and strengthens the management of the wellbore.

Description

technical field [0001] The invention relates to the technical field of automatic collection of production parameters of oil wells, in particular to a method and a system for obtaining online real-time data of the moving liquid level of a pumping well. Background technique [0002] At present, the construction of "digital oilfields" is being vigorously carried out in various domestic oilfields, and one of the important contents of "digital oilfields" is the automatic collection and management of oil well production parameters. At present, the automatic monitoring technology carried out in pumping wells realizes the power display through real-time monitoring of parameters such as wellhead back pressure of pumping wells, pumping unit load, stroke, stroke times, current and voltage during motor operation. Real-time testing of graphs, online metering of oil well dynamometer graphs and other functions. [0003] However, before the appearance of this technology, the dynamic liquid...

Problems solved by technology

[0003] However, before the emergence of this technology, the dynamic liquid level of the oil well has not yet been collected in real time.

At present, the method of measuring the dynamic liquid level by using an echometer is commonly used in oil production plants to collect the data of the dynamic liquid level. This method is characterized by relatively low cost and relatively accurate data. Real-time monitoring of online data. In addition, under normal circumstances, an oil well can only obtain dynamic fluid level data once or several times a month, and managers cannot timely understand the continuous fluctuation of dynamic fluid level.
